The curriculum will be designed to change students' knowledge, perceptions of norms, beliefs, self-efficacy, interpersonal skills (i.e., refusal skills), and high-risk behaviors related to HIV. The curriculum will include use of peer facilitators for selected lessons such as role playing. Intervention strategies will include demonstrations of skills by role playing, use of role model stories, and other experiential learning techniques. The Safer Choices curriculum will be modified to combine the 9th and 10th grade lessons to select those lessons which best match with the learning objectives for high-risk youth. The curriculum will be delivered during the school days by facilitators (project staff) who will receive intensive training prior to implementation and coaching and support during implementation. The Teacher Training Protocol used for Safer Choices will be adapted to train facilitators.
