Executive Summary
Pre-K 4 SA served more than 2,000 children during its fourth year of implementation. The Year 4
evaluation of Pre-K 4 SA sought to address research questions regarding attendance, quality, and
kindergarten readiness.
Pre-K 4 SA served slightly more boys (50.6%) than girls (49.4%) during Year 4. The majority of Pre-
K 4 SA children were Hispanic (76.3%), with the remaining children identified as Black (9.2%),
White (8.0%), and other ethnicities (6.5%). Seventy percent of children attended Pre-K 4 SA free;
9.6 percent on scholarship; and 20.4 percent were tuition-paying children. Of those children who
attended Pre-K 4 SA free, 89.8 percent did so based on income eligibility.
Average attendance for Pre-K 4 SA children was 92.4 percent, which increased slightly to 93.6
percent when children who withdrew were excluded. Attendance rates have been stable over the
first 4 years of implementation.
Westat conducted classroom observations using the Classroom Assessment Scoring System
(CLASS) to assess the quality of teacher-child interactions in Pre-K 4 SA classrooms. Overall,
teachers were observed displaying high levels of emotional support and relatively high levels of
classroom organization. Instructional support was, on average, nearing the middle of the mid-range
and improved the most of the three quality domains since the inception of the program. The level of
quality across all three domains was above the most recent available average quality scores of the
state’s and nation’s Head Start grantees in Emotional and Instructional Support while similar in
Classroom Organization. Additionally, average scores across all three CLASS domains were above a
cited “research threshold” for quality. No significant differences were found for any CLASS domain
across centers suggesting similar quality experiences for all Pre-K 4 SA children.
New in Year 4, results from a directly assessed measure of executive function showed scores slightly
higher than those found during the spring in a recent evaluation of another large city pre-K initiative
for a sample of more than 450 Pre-K 4 SA children.
Finally, Pre-K 4 SA children’s kindergarten readiness outcomes (measured by the Teaching
Strategies’ GOLD) were compared to a nationally representative sample of children for six
outcomes: cognitive, literacy, mathematics, oral language, physical, and social-emotional. Results
indicated that although Pre-K 4 SA children started the school year significantly below the normed
Pre-K 4 SA Evaluation Report: Year 4
vi
sample on five of the six outcomes, they surpassed the normed sample in three outcomes (cognitive,
literacy, and mathematics) by the end of the year, and eliminated the initial gap in oral language,
physical, and social-emotional.
Limitations of the evaluation include the lack of a control group of children for a comparison to a
more similar group of children, as well as lack of direct child assessment measures collected both in
the fall and spring to measure growth. Classroom observation data were also based on one
observation of each classroom during the spring. Therefore, no inferences can be made about
changes in classroom quality over time.

Introduction
Improving children’s kindergarten readiness and narrowing the achievement gap are twin education
goals receiving considerable attention throughout the United States (Barnett, 2011). Public
investments in preschool education programs have been promoted on the grounds that they can
accomplish these twin goals and produce benefits that lead to a high rate of return over time
(Campbell, Ramey, Pungello, Sparling, & Miller-Johnson, 2002; Heckman, Moon, Pinto, Savelyev, &
Yavitz, 2010; Reynolds, Temple, White, Ou, & Robertson, 2011; Rolnick & Grunewald, 2003).
As a result of the evidence for high-quality early education and the recent loss of state-funded seats
and slow growth of state programs, new initiatives are emerging. This includes programs at the city
level to increase school readiness, decrease achievement gaps, and align early care and education
programs with K–12 education systems. San Antonio, Texas, is among several cities that have opted
for investing in preschool education, in addition to state mandates, much like the Boston pre-K
program (National League of Cities, 2012). San Antonio is unique because the city has funded the
program through a voter-approved 1/8 cent increase in local sales tax rates starting April 1, 2013.
The program, called Pre-K 4 SA, serves many children who are at risk for falling behind their peers
and for lacking in kindergarten readiness, with the goal of increasing early childhood quality and
school readiness across the city of San Antonio. Pre-K 4 SA completed a fourth year of
implementation as of the completion of the 2016–17 school year.
The purpose of the current report is to present Year 4 evaluation findings of the Pre-K 4 SA
program. Investigations included (1) information concerning child attendance, classroom quality
information, executive function, and (2) outcome analysis results of the Teaching Strategies GOLD
assessment, which is the primary outcome of interest at the end of the pre-K year.
Research Questions
The Year 4 (2016–17) evaluation of Pre-K 4 SA sought to address the following four main research
questions:
1. What were the reported levels of child attendance during the pre-K year?
a. Are attendance rates stable over implementation years?
Pre-K 4 SA Evaluation Report: Year 4
2
2. What was the overall observed teacher-child interaction quality in Pre-K 4 SA
classrooms in Year 4?
b. Did the Year 4 interaction quality vary by center?
c. Has improvement been observed in interaction quality since the inception of the
program?
3. How do Pre-K 4 SA children preform on a direct assessment of executive function
skills?
4. How do Pre-K 4 SA children compare to a nationally representative normed sample of
children on GOLD outcomes?
a. Do differences in gains in GOLD outcomes vary significantly by center or
amount/level of teacher-child interaction quality?
Evaluation Sample and Methods
In this section, demographics characteristics for the sample are provided for children served during
the 2016-17 school year (Year 4) as well as a brief discussion of methods used.
Sample
Data were provided for 2,060 children in Year 4. Pre-K 4 SA served slightly more boys (50.6%) than
girls (49.4%). Of those more than 2,000 children, the majority represented three districts: Northside
Independent School District (ISD), San Antonio ISD, and North East ISD.1 In addition,
20.4 percent of children paid tuition, and 9.6 percent received scholarships (all other children
attended at no cost). Table 1 includes the percentage of children per represented school district.
1 These same three districts were also the majority representation in Years 1, 2, and 3 (2013-14 to 2015-16).

The average age of attending children on the first day of school (August 22, 2016) was 4.46 years.2
The majority of Pre-K 4 SA children were Hispanic (76.3%) with the remaining children reported as
Black (9.2%), White (8.0%), and other ethnicities (6.5%). Out of all children enrolled (both tuition
and free attending), 85.3 percent were considered economically disadvantaged. Of the children who
attended free, this number rose to 89.8 percent. It is important to note, 189 scholarship children
may have also met income eligibility criteria (noted as economically advantaged); however, they were
not in an attendance zone of a partner school district. Table 2 includes the percentage of children,
by eligibility, who attended Pre-K 4 SA at no cost.

Methods
The first two research questions were addressed through analysis of existing Pre-K 4 SA databases
and results from classroom observations. To address the descriptive question pertaining to
attendance, data collected by Pre-K 4 SA were submitted to Westat and descriptively analyzed. To
address the descriptive and inferential questions, pertaining to classroom quality, data were collected
and analyzed from the Classroom Assessment Scoring System (CLASS) (Pianta, La Paro & Hamre,
2008). CLASS is an observational system that assesses classroom practices in preschool by
measuring the interactions between children and adults. Observations in the Year 4 evaluation
consisted of five 20-minute cycles, followed by 10-minute coding periods.
To address the third research question concerning children’s executive function abilities, data were
collected and analyzed for a randomly selected group of 471 children, using the Pencil Tap direct
assessment (Diamond & Taylor, 1996). Executive function skills, in general, have been identified as
an important focus for targeting school readiness and success (Razza & Raymond, 2015).
Percentages correct were calculated and used for analyses after summing all correct and incorrect
responses, with possible scores ranging from 0 to 16. Once percentages were calculated, these data
were descriptively analyzed. Regression analyses were also conducted to explore the relationship
between executive function scores and child demographic information. Two-level, multilevel
analyses were conducted to examine the relationship between Pencil Tap spring scores and
classroom CLASS domain scores.
To address the final research question, inferential tests of differences were conducted between the
Pre-K 4 SA children and a nationally representative normed sample of children on the Teaching
Strategies GOLD assessment outcomes. GOLD is a teacher-report measure that collects
information on children’s progress in 36 objectives, three times throughout the year, across six main
categories: cognitive, literacy, oral language, mathematics, physical, and social-emotional. In addition,
inferential tests were conducted to investigate potential differences in GOLD results by center and
whether differences in observed teacher-child interaction quality were related to greater gains in
GOLD outcomes for children. See the Appendix for more detailed information on the Year 4
evaluation methodology, including detailed information pertaining to measures used.

Evaluation Results
Child Attendance in Pre-K 4 SA
Children began attending Pre-K 4 SA at different times. The majority of children (93.2%) began at
the start of the academic year (August 22, 2016). The last date children began Pre-K 4 SA was
March 22, 2017.3 Because of these varied dates, some children had the opportunity to attend more
days than other children. In fact, the range of possible membership days was 1–177 days, with an
average of 166.5 days. Average percentage attendance across all children was 92.4 percent. When
considering children who stayed in membership with Pre-K 4 SA through the year (did not
withdraw), the attendance percentage increases slightly to 93.6 percent.
Over the course of the year, 193 children withdrew from Pre-K 4 SA. The earliest withdrawal
occurred on August 23, 2016, with the last on May 31, 2017. Nearly 41 (40.9%) of the withdrawals
occurred before the end of December. No significant differences were found between children who
did and did not withdraw in terms of gender (t (1, 2,052.5) = -1.25, p = .21); eligibility to attend
Pre-K 4 SA free, on scholarship or tuition (F (2, 2,057) = 1.94, p = .14); or economic disadvantage
(t (1, 2,058) = 0.58, p = .56). One difference was found with respect to race/ethnicity (F (3, 2,056) =
7.55, p<.001).4 Children identified as Black (n = 28; 14.8%) or other ethnicities (n = 23; 17.2%) were
more likely to withdraw from Pre-K 4 SA compared to Hispanic children (n = 122; 7.8%). No other
statistically significant differences were found with respect to race/ethnicity.
Attendance Rates Over Time
Attendance rates have remained relatively stable over the first 4 years of Pre-K 4 SA
implementation. On average, rates have consistently remained between 91–94 percent.
Table 3 displays attendance for all children who attended the program as well as attendance for the
subgroup of children who did not withdraw from the program.
3 Although some children did not begin membership in Pre-K 4 SA until late spring, more than 99 percent of all children
were in membership by the end of the 2016 calendar year.
4 Results from Levene’s test of homogeneity of variances showed equal variances could not be assumed; therefore, a
Welch’s ANOVA was conducted.

Pre-K 4 SA Teacher-Child Interaction Quality
All 100 Pre-K 4 SA classrooms were observed during Year 4 using the CLASS. Of the 100
classrooms observed, 25 were located at the East center, 25 at the North center, 25 at the South
center, and 25 at the West center.
Scores for the Emotional Support domain ranged from 3.65–7.00 (on the 1 to 7 scale) across all five
observation cycles, with most scores in the high range of Emotional Support (average score of 6.24),
suggesting effective teacher-child interactions were observed most often during the observation
period. Slightly lower, with an overall score at the upper end of the middle range, Classroom
Organization domain scores ranged from 2.47–7.00, which suggests classrooms showed a mix of
effective interactions with periods when interactions were not as effective with regard to Classroom
Organization (average score of 5.60). Finally, Instructional Support domain scores ranged from
1.53–6.07, with an average score at the low end of the middle range at 3.55, which suggests only
some observed interactions included support from teachers that extended children’s thinking or
asked questions that encouraged children to analyze and reason throughout the observation period.
Visual representations of each of the Year 4 CLASS domain scores are provided in Figure 1.

Looking further into the average Emotional Support domain scores, only 24 percent of classrooms
(n = 24) were observed in the middle range, while 76 percent of classrooms observed provided high
levels of Emotional Support in the classroom (n = 76). Sixty-five percent of classrooms (n = 65)
were observed providing low or middle range Classroom Organization quality, while the remaining
35 percent (n = 35) were observed providing high levels of Classroom Organization. Finally,
49 percent of the classrooms (n = 49) were observed providing low levels of Instructional Support,
51 percent (n = 51) were observed providing middle or high levels of Instructional Support. Table 4
provides average scores by each of the 10 dimensions and 3 domains.

a Negative Climate is initially scored with lower values representing no or low negative climate. These scores are then reverse-coded to
reflect the same direction (higher values are positive) as the other dimensions.
Past research using the CLASS has often noted the low scores that are commonly seen with respect
to the Instructional Support domain (LaParo, Pianta, & Shuhlman, 2004; Locasale-Crouch et al.,
2007; Mashburn et al., 2008). To place Pre-K 4 SA CLASS scores in context, the National Institute
of Early Education Research (NIEER) (Barnett & Friedman-Krauss, 2016) recently found average
scores across Texas and the United States to be lower than those found in the current study.
Additionally, Barnett & Friedman-Krauss (2016) compared state and national findings by research
thresholds; Pre-K 4 SA scores are visually depicted along with Texas and national Head Start
average scores as well as stated research thresholds (see Figure 2). Previous research has found that
children in classrooms with Emotional Support scores over 5 also have higher teacher ratings of
social competence and lower ratings of behavior problems, while children from classrooms with

Instructional Quality ratings of 3.25 or above score higher on measures of reading, mathematics, and
expressive language (Burchinal, Vandergrift, Pianta, & Mashburn, 2010).5

5 During the time the study data were collected, the CLASS was broken into two rather than three domains—Emotional
Support and Instructional Quality. Direct comparisons of Burchinal et al., 2010 study findings to those presented in the
current report should not be made as the dimensions within each domain are not consistent.

Interaction Quality by Center
The three CLASS domains were analyzed to determine if there were significant differences in
classroom teacher-child interactions across Pre-K 4 SA centers. No significant differences were
found, by center, on any of the three CLASS domain scores, thus, suggesting that statistically
equivalent quality was observed, on average, across the four Pre-K 4 SA centers. More specifically,
this indicates similar quality classroom experiences offered across Pre-K 4 SA centers for students.
Interaction Quality Over Time
During the first 4 years of implementation, 100 percent of Pre-K 4 SA classrooms were observed.
As seen in Figure 3, the overall Emotional Support and Classroom Organization scores have been
relatively stable overtime; however, scores did drop slightly between Years 3 and 4. A relative
increase has been seen in the Instructional Support domain since the inception of the program
(0.73). When compared to Year 1, Year 4 CLASS domain scores for Emotional Support and
Classroom Organization were not significantly different; Instructional Support was (Z = -2.00,
p = .045).6 Figure 2 depicts the change in average interaction quality for the program over time.

Executive Function
A randomly selected group of 500 Pre-K 4 SA children were selected to participate in the Pencil
Tap; 471 students (94.2% of the selected group) were assessed using the Pencil Tap during the
spring of the pre-K year. On average, Pre-K 4 SA children’s percentage of correct responses was
nearly 78 percent (77.6%). This average percentage of correct responses is nearly 8 percent (7.7%)
higher than a recent city-level pre-K evaluation from New York (Westat, Metis Associates, & Branch
Associates, 2016). Figure 4 presents the city-level pre-K program results.
Figure 4. Pencil tap correct responses
Note: This visual representation is for descriptive purposes only; no statistical tests have been conducted between the Pre-K 4 SA and
New York samples for this evaluation.
A stepwise, linear regression analysis was conducted to investigate whether student demographics
explained any of the variance in executive function as measured by the Pencil Tap at the end of the
pre-K year.7 Two factors, gender and enrollment status, were found to significantly predict executive
function. More specifically, girls were found to display significantly higher executive function skills
as compared to boys, (β = .10, t(464) = 2.25, p = .025) and tuition children were found to display
significantly (although marginally) higher executive function skills as compared to children attending
for free (β = .10, t(464) = 2.01, p = .045). It is important to note that these differences may have
existing upon entry into the pre-K year. No significant differences were found in relation to
race/ethnicity, economic disadvantage, English language learner status, or military family status.
7 As CLASS scores were not predictive of executive function scores in the spring, a more parsimonious model that only
included child demographics was run; those results for the two demographic factors are reported here.

No significant relationship was identified between executive function and CLASS scores.8 This may
be due to existing executive function differences at the beginning of the pre-K. The Year 5
evaluation will address this limitation by collecting executive function data at the beginning and end
of the school year so that gains in executive function scores can be explored in relation to the
classroom quality provided by Pre-K 4 SA.
Teaching Strategies GOLD
Pre-K 4 SA used the GOLD assessment to collect information on children at three time points
throughout the academic year: fall, winter, and spring. Children (89.37%; n = 1,841) were included
in analyses if they had outcome data for all three time points in at least one of the following six
outcomes: cognitive, language, literacy, mathematics, physical, and social-emotional. No significant
differences were found between children included and not included in analyses for gender (2(1) =
0.092, p = .762) or free lunch status (2(1) = 0.001, p = .983); however, differences were found for
tuition status (2(1) = 4.500, p = .034) and race (2(6) = 16.085, p = .013). More specifically,
children able to be included in at least one outcome analysis were more likely to be tuition children
(Z = 2.12, p = 0.034). For race, children who were included in at least one outcome analysis were
more likely to be Hispanic (Z = -3.21, p = .001) and less likely to be African American (Z = -2.453,
p = 0.014) compared to all other racial categories.
As data were not collected on a comparison or control group, comparisons were conducted using
the nationally representative normed data for the GOLD assessment (Lambert, Kim, & Burts,
2013). When starting Pre-K 4 SA, children began the fall significantly below the normed sample on
five of the six GOLD outcomes; Pre-K 4 SA children began the year similar to the normed sample
in mathematics. By spring, the Pre-K 4 SA children scored statistically significantly (p<.001) higher
than the normed sample on three outcomes (cognitive, literacy, and mathematics). In two of those
(literacy and mathematics), Pre-K 4 SA children already significantly exceeding the normed group in
by the winter time point. Effect sizes (Hedges’ g) for the significant results ranged from small
(0.31 for cognitive) to medium (0.49 literacy and 0.66 for mathematics). Over the course of the pre-
K year, Pre-K 4 SA children gained an additional 31.92 scale score points (27.8% more) in cognitive,
8 A multilevel modeling approach was used as individual child assessments (Pencil Tap) were clustered within classrooms
(Raudenbush & Bryk, 2002). A two-level model was used, with children at level 1 and classrooms at level 2.

30.32 scale score points (35.4% more) in literacy, and 31.33 scale score points (38.7% more) in

Spring results for the oral language, physical, and social-emotional outcomes indicated the initial
gaps between Pre-K 4 SA children and the normed sample for all three outcomes were eliminated by
the end of the school year. By spring, no significant differences were found between Pre-K 4 SA
children and the normed sample for oral language, physical, or social-emotional. To achieve the
elimination of the initial gaps, Pre-K 4 SA children gained an additional 18.46 scale score points
(16.5% more) in oral language, 16.18 scale score points (15.2% more) in physical, and 21.70 scale
score points (19.4% more) in social-emotional than the normative group of children. See Table 5.

Differences in Readiness Outcomes
Analyses were also conducted within the Pre-K 4 SA sample to explore potential differences related
to GOLD outcomes for children. These analyses were conducted between centers and to explore
the variance in GOLD outcomes accounted for by the three CLASS domains: Emotional Support,
Classroom Organization, and Instructional Support. Results showed there was no significant
variation in growth across centers for all six GOLD outcomes; meaning the average growth was the
same for children in all four centers. Additionally, across all six GOLD outcomes, results for the
three CLASS domains were non-significant. This indicates teacher and child interactions in the
classroom were not related to child outcomes on the GOLD assessment, after taking into account
demographic characteristics of the children.
Limitations and Recommendations
Three important limitations of the Year 4 evaluation require mention. First, the current evaluation
ultimately rests on a primary outcome that is a teacher report rather than a direct child measure
conducted by unbiased data collectors. Because a teacher-report measure is the primary outcome of
interest, variance in the results related to teacher bias or other teacher factors cannot be excluded.
Pre-K 4 SA did add the Pencil Tap in the spring as a direct assessment of children’s executive
function skills; however, no information was collected in the fall. During Year 5, Pre-K 4 SA has
included a pre-, post- assessment of executive function using the Pencil Tap, which will allow for the
measurement of growth across the pre-K year in executive function skills. We continue to encourage
the consideration of adding an additional directly assessed outcome measure such as oral language or
another outcome of primary interest to Pre-K 4 SA.
Second, due to resource constraints, Westat was not able to collect information on a control or
comparison group of children with which to compare the Pre-K 4 SA children with respect to
kindergarten readiness outcomes. This is important because the normed sample that was used for
comparison purposes is most likely very different from the Pre-K 4 SA children. Normed samples
are created to be reflective of the demographic proportions similar to those found in the U.S
Census. When a comparison or control group can be formed with children who are most like the
Pre-K 4 SA children, more confidence can be had with respect to resulting differences on outcomes,
meaning there can be more confidence that differences are the result of the program in question and
Pre-K 4 SA Evaluation Report: Year 4

not a result of other factors.9 This is particularly true when using a control group formed from
random assignment into the program. A recommendation related to this limitation is the
consideration of additional funding to form a control group of children based from the lottery
selection process for admittance to Pre-K 4 SA. Data can be collected from this group and
compared between children who attend Pre-K 4 SA and children who do not.
Third, classroom observation data are based on one observation of each classroom during the
spring. As such, no inferences can be made about changes in classroom quality over time. Although
this was primarily due to resource and time constraints. Consideration should be given to
conducting multiple observations across a year (in a random selection of classrooms) to begin to
understand potential changes or consistencies in classroom interactional quality.
9 One way to form such a group of children, similar in nature to Pre-K 4 SA children, would be to work with Teaching
Strategies to create a matched comparison group from the normed sample of children in the future.

Evaluation Methods
Here we provide information on measures used in the Pre-K 4 SA Year 4 evaluation, as well as
detail on the analytic approach to analyses reported.
Measures
Classroom Assessment Scoring System (CLASS)
The CLASS (Pianta, La Paro & Hamre, 2008) is an observational system that assesses classroom
practices in preschool by measuring the interactions between children and adults. Observations in
the Year 4 evaluation consisted of five, 20-minute cycles, followed by 10-minute coding periods.
Scores were assigned during various classroom activities, and then averaged across all cycles for an
overall quality score.
Interactions were measured through 10 different dimensions (see Table A-1 for descriptions of each
CLASS dimension) that are divided into three larger domains. The Emotional Support domain is
measured through the use of four dimensions: positive climate, negative climate, teacher sensitivity,
and regard for student perspectives. The CLASS also measures Classroom Organization through
three dimensions: productivity, behavior management, and instructional learning formats and
Instructional Support through three dimensions: concept development, quality of feedback, and
language modeling.
The CLASS uses a 7-point Likert-type scale, for which a score of 1 or 2 indicates low-range quality
and a score of 6 or 7 indicates high-range quality. Each dimension and domain is assigned a score
during each 20-minute cycle (or, observation period). The number of children and adults in the
classroom was also recorded during each 20-minute cycle.

Table A-1. Descriptions of CLASS dimensions
Domain
Dimension
Description
Emotional
Support
Positive Climate
Reflects the emotional connection between teachers and
children and among children, and the warmth, respect, and
enjoyment communicated by verbal and nonverbal
interactions.
Negative Climate
Reflects the overall level of expressed negativity in the
classroom. The frequency, quality, and intensity of teacher
and peer negativity are key to this dimension.
Teacher Sensitivity
Encompasses the teacher’s awareness of and
responsiveness to students’ academic and emotional needs.
Regard for Student
Perspectives
Captures the degree to which the teacher’s interactions with
students and classroom activities emphasize students’
interests, motivations, and points of view and encourage
student responsibility and autonomy.
Classroom
Organization
Behavior Management
Encompasses the teacher’s ability to provide clear behavior
expectations and use effective methods to prevent and
redirect misbehavior.
Productivity
Considers how well the teacher manages instructional time
and routines and provides activities for students so that they
have the opportunity to be involved in learning activities.
Instructional Learning
Formats
Focuses on the ways in which teachers maximize students’
interest, engagement, and abilities to learn from lessons
and activities.
Instructional
Support
Concept Development
Measures the teacher’s use of instructional discussions and
activities to promote students’ higher-order thinking skills
and cognition and the teacher’s focus on understanding
rather than on rote instruction.
Quality of Feedback
Assesses the degree to which the teacher provides feedback
that expands learning and understanding and encourages
continued participation.
Language Modeling
Captures the effectiveness and amount of teacher’s use of
language-stimulation and language-facilitation techniques.
Pencil Tap
The Pencil Tap is a brief direct measurement of children’s executive function skills. It is one of
seven age-appropriate tasks that make up the Preschool Self-Regulation Assessment (PSRA). Prior
to the PSRA, the Pencil Tap emerged from the peg-tapping task (Blair, 2002; Diamond & Taylor,
1996). Executive function skills, in general, have been identified as an important focus for targeting
school readiness and success (Razza & Raymond, 2015). Previous research has also found
differences between “cool” executive functioning tasks (such as the Pencil Tap task, which involve
problem solving and cognitive flexibility), and “hot” executive functioning tasks, which require the
regulation of emotions during problem solving (Bassett, Denham, Wyatt, & Warren-Khot, 2012;
Pre-K 4 SA Evaluation Report: Year 4
A-3
Brock, Rimm-Kaufman, Nathanson, & Grimm, 2009; Mann, Hund, Hesson‐McInnis, & Roman,
2017). Additionally, children’s “cool” executive functioning has been found to predict children’s
later school achievement, including literacy and mathematics outcomes (Brock, et al., 2009;
Willoughby, Kupersmidt, Voegler-Lee, & Bryant, 2011).
The Pencil Tap task is a “cool” executive function task that requires children to inhibit a natural
tendency to mimic the action of the experimenter while remembering the rule for the correct
response, and is thought to assess inhibitory control, attention skills, and working memory. When
the test administrator tapped a pencil once, the child was directed to tap their pencil twice. When the
administrator tapped twice, the child was directed to tap once.
Teaching Strategies GOLD
The GOLD is a teacher-report measure selected and used by Pre-K 4 SA that collects information
on children’s progress in 36 objectives across six main categories: Cognitive, Literacy, Oral
Language, Mathematics, Physical, and Social-Emotional. (Other categories are available to be
tailored to specific programs.) The GOLD assessment is conducted at three time points throughout
the year: fall, winter, and spring.
Analytic Approach
Research questions were addressed through analysis of study-collected data as well as existing
Pre-K 4 SA databases. To address the first questions, What were the reported levels of child attendance
during the pre-K year? and Are attendance rates stable over implementation years?, data collected by Pre-K 4 SA
were submitted to Westat and descriptively analyzed. To address the questions, What was the overall
observed teacher-child interaction quality in Pre-K 4 SA classrooms in Year 4? and Did the Year 4 interaction
quality vary by Center?, data were analyzed from the CLASS observations both descriptively and
inferentially using analysis of variance (ANOVA). To assess whether improvement had been observed in
interaction quality since the inception of the program? The Wilcoxon Mann-Whiney test were conducted by
domain as scores were not normally distributed. To address the direct assessment question, How do
Pre-K 4 SA children preform on a direct assessment of executive function skills?, the percentage of correct
responses were calculated and descriptively analyzed. Regression analyses were then conducted to
explore the relationship between executive function scores and child demographic information.
Pre-K 4 SA Evaluation Report: Year 4
A-4
Additionally, two-level, multilevel analyses were conducted to examine the relationship between
Pencil Tap spring scores and CLASS domain scores.
The primary outcome research question, How do Pre-K 4 SA children compare to a nationally representative
normed sample of children on GOLD outcomes? was addressed through independent samples t-tests
between the Pre-K 4 SA children and a nationally representative normed sample of children on the
GOLD assessment outcomes. In addition, inferential tests were conducted to investigate potential
differences in GOLD results by center and whether differences in CLASS domain scores were
related to higher GOLD outcomes for children. More specifically, three-level, multilevel models
were used to investigate center differences, and the potential relationships between CLASS domain
scores and GOLD outcomes. A multilevel modeling approach was used as individual child
observations were clustered within classrooms and centers (Raudenbush & Bryk, 2002). The three-
level model used included children at level 1, classrooms at level 2, and centers at level 3.
The full model for GOLD growth is denoted as:
= 000 +0 +00+
where is the individual growth for child i in classroom j in center k, 000 is the overall
grand mean growth score, 0 is the deviation of teacher j in center k, and 00 is the deviation of
center k, and is the deviation of child i in classroom j in center k. No covariates were added to
the model for two reasons. There was a small sample size of four centers at level 3 and because most
of the available child covariates were dichotomous. The combination of these reasons would likely
result in the model failing to converge (West, Welch, & Galecki, 2007).
