Public schools are a critical site for drug abuse prevention and education. Although in recent years prevention curriculum developers have been able to identify successful strategies, it is not clear how well these findings have been transferred to local schools. This article reports on a study of schools that have developed their own drug abuse prevention curriculum. The process that these schools used is compared to a model of curriculum development. In general, the process that local schools use is characterized by high levels of involvement by a variety of personnel, low levels of training, little use of resources outside the school corporation, poor training of teachers who will be implementing the curriculum, and little evaluation. Availability of external funds for development from federal or state sources were powerful motivators for curriculum development. Recommendations for changes in professional development and curriculum materials availability are made.
