Sampling Plan and 18-Month Follow-Up Survey Plan for the National Evaluation of PROMISE Demonstration Programs

This report presents Mathematica’s plans for selecting the survey samples for the national evaluation of PROMISE demonstration programs and conducting the first of two planned follow-up surveys, at 18 months after youth enroll in the evaluation and are randomly assigned to treatment or control groups. A subsequent report will present our plans for a second follow-up survey five years after enrollment and random assignment.
