City-as-School (CAS) is an alternative high school linking students to various out-of-school learning experiences throughout New York City. In 1985, the CAS was awarded a National Diffusion Network (NDN) four-year replication grant, given to exemplary programs to enable them to disseminate their model to other interested schools and districts throughout the country. The 1986-87 school year represented CAS's second full year of replication activities. In contrast to 1985-86, when CAS/NDN team members attended several general educational conferences, in 1986-87 initial awareness sessions took place only at alternative schools and NDN conferences, or at state governors' conferences that CAS was officially invited to attend. Eight districts around the country were selected for 1986-87 training as replicators, and will begin replication activities in fall 1987. The project's follow-up support, technical assistance, and in-service training objectives were achieved. CAS addressed the recommendations made in last year's Office of Educational Assessment report with the result that increased staffing and the addition of a full-time director have given the replication program a tighter structure with clearer objectives; also, the addition of replicator districts in New Jersey, Alaska, and Washington, D.C., has given the project a broader, more balanced geographical spread. Recommendations for next year are offered. (BJV)
