This report represents the first of three that will be released over the course of the study. It answers two primary questions: (1) How has Boston Coaching for Completion (BosC4C) been implemented? and (2) What was the cost to implement the program? Over the 2015-16 academic year, the study collected data, including by conducting intensive interviews with staff from the nonprofit organizations and from 10 partner colleges; administering an online survey to participating students; conducting focus groups with non-participating students; and analyzing information from the program's records of coaches' interactions with students. This report is designed to help develop a common standard of practice by describing the nonprofit coaching organizations' and colleges' activities, students' experiences, commonalities and differences across the organizations, and costs of implementing the BosC4C program. It also outlines the elements of transition coaching that appear to be consistent across the nine nonprofit organizations--as well as idiosyncratic to individual organizations--and describes challenges faced by organizations and their staff and by students. Based on what we learned, several themes have emerged.
