The Yap Classroom Assessment Project is an attempt to introduce new methods of assessment, with an emphasis on performance assessment, into the practices of teachers in the Pacific, integrating the strengths of Yapese culture with children's education. The project, developed by the Pacific Region Educational Laboratory (PREL), concentrates on systemic reform and a sustained training program that trains Micronesian teachers in Yap sequentially and repeatedly over time. The model calls for onsite involvement of teachers throughout Yap, taking services to the schools, and for continuing teacher support. Each of four defined phases involves gradually moving training responsibilities from external resources to the Yap team, including introduction of expanded assessment knowledge and skills, teacher workshops, and finally training teachers independent of the PREL. The ultimate success of an endeavor of this sort depends on community involvement. The people and educators of Yap have demonstrated their involvement, and the training continues, evolving as it grows. (Contains 4 references.) (SLD)
