The study examined the effects of the U.S. Department of Education's Student Mentoring Program (SMP) on students' interpersonal relationships, academic outcomes, and delinquent and risk behaviors. The study focused on approximately 2,600 at-risk fourth-through- eighth-grade students in 32 SMP sites. Applicants were randomly assigned to a program group that was offered SMP services or to a control group that was not. Control-group students were free to receive mentoring services through other programs. The authors collected data on students' interpersonal relationships and delinquent and risk behaviors through student surveys. They collected data on course grades, statewide assessment scores, and disciplinary infractions from school records. Study authors found that the student mentoring program had no statistically significant effect on the academic and behavioral outcomes they examined once they adjusted their statistical tests for the analysis of multiple outcomes. What Works Clearinghouse (WWC) found the research to be consistent with WWC evidence standards, cautioning that 20-35 percent of students in the original sample were missing school records data, depending on the outcome. These students are excluded from the analyses of grades, test scores, and disciplinary infractions.
