This article discusses the benefits and successes of the NGO, GAPA-Bahia Project, started in 1992, to involve students and teachers in developing an AIDS prevention education program and evaluation. The project sought to help youth make decisions that result in a healthy, safe, and pleasurable sexual life and to encourage acceptance and support for people living with HIV and AIDS. The involvement of teachers and students in project design allows for greater adaptation and utility. The project initially collected information from teachers and students about sexuality, death, fear, prejudice, and expectations about male and female behavior; additional information was collected from role playing and discussions. The information was used to plan the curriculum and teacher training. Project staff met with teachers monthly for support and supervision. Teachers' feedback was incorporated into future planning activities. Daily activities were recorded by teachers and students. Daily records indicated personal feelings about the day, the issues under discussion, and the impact of these issues on their own lives. The project conducted review sessions with teachers, students, and trainers. One particularly successful training exercise involved identifying an individual's view on a sheet of paper and posting it along with others' views on a wall for all to comment on and prioritize. Outreach activities include special days when out of school youth, parents, and other community members are invited to visit and attend small group discussions and workshops. Simple and regular monitoring of project activities results in easy adaptations in a staged process. Community participation results in an expanded role beyond just the recipient one.
