Mentoring is being embraced by many schools as a way to fill gaps in the lives of children classified as "at-risk." Several lines of research indicate that mentoring programs encouraging positive adult relationships with these students provide the support needed to help these children reach their full potential. Through a collaborative effort between Rodriguez Elementary School, located in inner city San Antonio (Texas), and Our Lady of the Lake University, also in San Antonio, a very successful mentoring program involving college students and elementary school students is underway. As part of a state grant, a research program accompanied the mentoring program. By 1993-94, the program had grown to include over 130 college students, providing mentors for many of the school's 370 students. Using a one-group pretest-posttest design, the Piers-Harris Children's Self-Concept Scale was administered to elementary students involved in the mentoring program. While the results were not statistically significant, the data indicate a positive trend in students' self-concept and also indicate that the collaborative mentoring program is having a positive effect on students' self-esteem.
