Study enrollment began in fall 1999 and continued through fall 2001. Youth are surveyed at or close to study enrollment (wave 1), between 6 and 12 months following enrollment (wave 2), and then 18 to 36 months later (wave 3). In sites where program participation might be expected to affect school performance, school records will be collected through spring 2004. Throughout, data on program operations are being collected through observations, executive interviews, program documents, and focus groups.

A report on the effectiveness of the programs in achieving their short-term goals of changing knowledge, attitudes, and near-term behavioral choices will be completed in early 2003, after Wave 2 survey data are available for the full study sample. The final study evaluation report will be completed in summer 2005. During intervening periods, the team will prepare a limited number of special-focus reports that address particular questions of interest to Congress or the U.S. Department of Health and Human Services.
