PREP Evaluation

The PREP national evaluation will:

  • Document how state PREP programs are designed and implemented. States must decide how to distribute grant funds to local sub-awardees, what program models to authorize, and how to support implementation. Understanding the range of decisions made and how implementation unfolds can contribute to stronger future program design for pregnancy prevention and other programs.
  • Read the first report and its brief 

  • Measure and report on program performance. All PREP grantees will be required to submit standard information on program delivery, participant characteristics, and fidelity to program models. These measures will be used to monitor program performance and identify areas for program improvement.

Within a small number of selected sites, the PREP in-depth evaluation will:

  • Examine the impacts and implementation of PREP. In four sites, the evaluation will provide rigorous estimates of program effectiveness on key outcomes, such as rates of sexual initiation and abstinence, contraceptive use, and teen pregnancy. The evaluation will also include detailed assessments of program delivery. Evaluations are now underway in four sites.

The Personal Responsibility Education Program (PREP), funded under the Affordable Care Act of 2010, is a key element of the federal strategy to reduce teenage pregnancies and sexually transmitted infections (STIs). PREP provides grants to states, tribes, and tribal communities to replicate, or substantially incorporate elements of, programs that have been shown to be effective at delaying sexual initiation, reducing pregnancy, and increasing contraceptive use among sexually active youth. The selected programs must educate youth on both abstinence and contraception. Another aspect of the PREP program is that grantees must incorporate lessons on at least three of the following adulthood preparation subjects: adolescent development, healthy relationships, healthy life skills, parent-child communications, educational and career success, and financial literacy.

Upon authorizing the PREP program, Congress required that it be evaluated. The evaluation will help the federal government, states, tribes and tribal communities, and local service providers learn more about program design, implementation, and outcomes. The Administration for Children and Families (ACF) within the U.S. Department of Health and Human Services (DHHS) has contracted with Mathematica Policy Research to document and assess this large-scale replication effort. The evaluation will study PREP programs nationwide, collecting data from all grantees, and will also conduct an in-depth examination of a few selected PREP sites.
