Performance-based scholarships have two main goals: (1) to give students more money for college; and (2) to provide incentives for academic progress. MDRC launched the Performance-Based Scholarship (PBS) Demonstration in 2008 to evaluate the effectiveness of these scholarships in a diverse set of states, institutions, and low-income student populations. The evaluation includes more than 12,000 students in eight institutions and one intermediary across six states to test different performance-based scholarship designs. Each of the programs in the demonstration was evaluated using a randomized controlled trial, widely considered to be the most reliable way to detect the impact of an intervention. Technical Details for the Pooled and Site-Level Estimates is appended. [This report was written with Sean Blake. A list of earlier MDRC publications on the performance-based scholarship demonstration is included.]
