Summer Training and Education Program (STEP) is a summer employment, academic remediation, and life skills program intended to lower school dropout rates by reducing summer learning loss and preventing teen parenthood. The program is integrated into the federal summer jobs program and is offered during six-to-eight-week sessions in two consecutive summers. It includes part-time summer work at minimum wage, a daily reading and math curriculum, and "life skills and opportunities" classes that focus on topics such as sexual behavior, drug use, careers, and community involvement. The program serves low-income 14- and 15-year-olds who have tested below grade level in either reading or math. The What Works Clearinghouse (WWC) reviewed three studies of STEP. Two of these studies do not meet either WWC evidence standards or eligibility screens. Based on the remaining study, a randomized controlled trial including more than 2,500 students in Massachusetts, California, Washington, and Oregon, the WWC found the intervention to have no discernible effects on either staying in school or progressing in school. The conclusions presented in this report may change as new research emerges. Six appendices are included. (1) Study Characteristics; (2) Outcome measures for the staying and progressing in school domains; (3) Summary of study findings included in the rating for the staying and progressing in school domains; (4) Summary of graduation rate findings; (5) STEP rating for the staying and progressing in school domains; and (6) Extent of evidence by domain.
