The Evaluation Instruments

Let's take a look at the instrument Jack and his evaluator selected. After some discussion, Jack and his evaluator decided to use the instrument required for Center for Substance Abuse Prevention (CSAP) grantees. It's the Youth Survey (12 years old and over), Government Performance and Results Act (GPRA) Client Outcome Measures for Discretionary Programs. This is a valid and reliable instrument for substance abuse prevention programs.
