The Portland Schools Foundation's (PSF) Ninth Grade Counts initiative is a network of more than twenty independent summer transition programs targeting Academic Priority (or "at-risk") students. These programs share a common focus on providing academic support, enrichment, and career/college exposure for students who show early warning signs for dropping out of school. The programs, which are sponsored by school districts, nonprofits, and colleges, vary in their format and curricula and are available to students identified as Academic Priority, as well as others, across Multnomah County (6 school districts) during the summer between eighth and ninth grades. The purpose of the Ninth Grade Counts summer transition programs is to re-engage Academic Priority students with their education through building skills, attitudes, and beliefs that lead to school success. The primary purpose of this report is to determine whether Academic Priority students who participated in a Ninth Grade Counts program during the summer of 2009 had better academic outcomes in the ninth grade than Academic Priority students who did not attend a program. Key findings include: (1) Ninth Grade Counts has a clear, positive effect on high school credit attainment; (2) Other results were less clear; and (3) There may be an effect for individual programs. In the process of performing this analysis of the Ninth Grade Counts summer 2009 program, some issues were identified that could increase the utility of future reports for this population. These are: (1) Ensure all schools report grade point average statistics for ninth grade; (2) Measure which students received high school credit for summer program participation; (3) Collect the names of courses students have taken, along with grades; and (4) Perform a multi-year study involving a full high school cohort. Appended are: (1) Complete Counts of Cohort 1 Students; (2) Average Performance of Cohort 1 Students; (3) District Data File Layout; and (4) Example of Program Report.
