Findings from the Institute for Student Achievement Outcome Evaluation
(Academy for Educational Development)
This six-year study followed two cohorts of ninth graders in New York City ISA schools. Compared to similar students in other schools, ISA students attended school, advanced to the next grade, and graduated at higher rates; earned more course credits; and failed fewer classes. They also were more likely to attend a four-year college full time and to continue their postsecondary education for more than one year. Read the executive summary and full report to learn more.
