This catalog provides an overview of all exemplary educational programs approved for national dissemination by Department of Education Review panels and introduces the National Diffusion Network (NDN), its programs, and services to schools. The programs described fall into three categories: (1) active projects; (2) limited activity projects; and (3) projects no longer offering services.
