Mentoring as a strategy to support high school students is assumed to impact students developmentally and cognitively, although evidence is still limited. We will discuss how best to study program design in relation to program impact on mentors and mentees. Interest derives from the piloting of a mentoring program that involved students from the Baruch College Honors Program and honors societies and high school sophomores and juniors from the High School for Public Service (HSPS) located in the Crown Heights section of Brooklyn. HSPS has a graduation rate of 98% with all of the graduates being accepted to college. However, of the students who enrolled at a CUNY school, more than half required remediation in either English or math. A mentoring program was piloted in winter 2011 to help these students improve their overall performance. The program’s goals are to help high school students succeed academically and socially.
