Given the paucity of information distinguishing the most salient and well-researched guidance curricula and resources, the overall goals of this article were, first, to investigate national trends in the use of curriculum materials within the context of comprehensive guidance and counseling programs and, second, to offer pre-service and in-service school counselors a summary of available curricula and resources that can be readily used in their guidance lessons. Comprehensive guidance and counseling programs are being implemented throughout the United States. One of the most widely used programs, the Missouri Model, includes a guidance curriculum as one of its central program elements. The authors discuss the results of a study exploring the national trends in the use of school counseling guidance materials. Implications for comprehensive guidance and counseling program implementation are included.
