3. The pregnancy prevention programs must have targeted youngsters 10-19 years of age. For STD/HIV/AIDS prevention programs, interventions targeting college students were also considered.

An ongoing process is used to select programs for the PASHA collection. The process begins with calls for nomination and extensive literature searches to identify candidate programs. After PASHA staff prepare briefing documents describing the development and evaluation of each intervention, a Scientist Expert Panel votes on the final selection. Practitioners, program developers and researchers are invited to submit information on promising programs to PASHA staff for consideration during the next round of program selection. Your participation in this process will ensure that PASHA represents the strength and diversity of the fields of teen pregnancy and teen STD/HIV/AIDS prevention.
