Cost is often a primary concern when policymakers and practitioners consider a new program. This brief provides information on the cost of implementing a teen pregnancy prevention program for 7th-grade boys. The information comes from an evaluation of the Wise Guys Male Responsibility Curriculum in Davenport, Iowa, which Mathematica conducted for the Administration for Children and Families within the U.S. Department of Health and Human Services. For the evaluation, a team of two trained facilitators from a local social service provider, Bethany for Families and Children, delivered Wise Guys as a 14-session voluntary elective class during the regular school day. Mathematica partnered with Bethany staff to collect information on the program’s cost, with the goal of understanding the resources required to provide the program and how its cost compares to other federally funded teen pregnancy prevention programs.
