Abstract
We present the results of a meta-analytic synthesis of the literature on the association
between the use of frequent low-stakes quizzes in real classes and students’academic
performance in those classes. Data from 52 independent samples from real classes (N=
7864) suggests a moderate association of d= .42 between the use of quizzes and
academic performance. Effects are even stronger in psychology classes (d=.47) and
when quiz performance contributed to class grades (d= .51). We also find that perfor-
mance on quizzes is strongly correlated with academic performance (k=19, N=3814,
r= .57) such that quiz performance is relatively strongly predictive of later exam perfor-
mance. We also found that the use of quizzes is associated with a large increase in the
odds of passing a class (k=5, N= 1004, odds ratio = 2.566).

Introduction
Frequent low-stakes testing is a popular teaching tool. Many instructors use it to provide
students with feedback on their understanding of recently covered class material. This practice
is both popular among instructors and generally well-received by students (e.g., Narloch et al.
2006;LyleandCrawford2011) and is also aligned with the theoretical frameworks of learning
and memory that seek to explain both the testing effect (Karpicke and Roediger 2007) and test-
potentiated learning (Roediger et al. 2011; Wissman et al. 2011), as well as the substantial
body of empirical experimental work upon which these theories are based.
The testing effect refers to the finding that having people take tests on material of interest
tends to lead to improved memory for that material. There are numerous theoretical
