The iMentor College Ready Program is a model that combines school-based mentoring with technology and aspects of whole school reform. The program aims to create strong relationships between low-income youth and college-educated mentors--and to leverage these relationships to help students develop the mindsets, skills, and knowledge necessary to enroll and succeed in college. To learn more about the process and efficacy of iMentor's approach, the Research Alliance for New York City Schools is conducting a mixed-methods evaluation of the College Ready Program in eight New York City high schools. The evaluation is examining iMentor's roll-out and implementation in these schools, its impact on a range of outcomes related to students in these schools, and its impact on a range of outcomes related to students' preparation for college. The first in the series, "Bringing Together Mentoring, Technology, and Whole School reform: A First Look at the iMentor College ready Program" (2015) examined the College Ready program's early implementation and presented preliminary program impacts for 9th grade students. Provided here is the executive summary of the second report in the series from the evaluation and highlights findings from "Focus on Mentee-Mentor Relationships. The 10th Grade Implementation of iMentor's College Ready Program." The current report focuses on iMentor's implementation in the 10th grade and explores the connection between various program activities and the development of close mentee-mentor relationships. iMentor's leaders theorize that these relationships are the primary outcome of interest for 9th and 10th grade students, providing the foundation for college readiness, application and enrollment work to take place in 11th and 12th grade.
