The Off to a Good Start: Physical, Emotional, and Sexual Development of Youth Grades 5-8 (OTAGS) curriculum provides students with a foundation for future sex education. The curriculum consists of three modules covering puberty, healthful relationships, and HIV and sexually transmitted infections. University of Illinois Extension educators taught OTAGS at 15 schools in Chicago and the surrounding suburbs. Evaluation results were favorable, indicating knowledge improvement. OTAGS complements other Extension programs, lays a foundation for future sex education, and provides others in Extension with the opportunity to play a role in making timely and accurate sex education accessible to youths.
