Project CLASS (Cooperative Learning: Acquiring Specialized Skills) was designed to develop, demonstrate, evaluate, and disseminate an inservice training model to enhance the early intervention competencies of professionals in rural states who are delivering Public Law 99-457 (Part H) community and home-based services to infants and toddlers with disabilities and their families. The inservice training model developed by Project CLASS was a linked model using a "train the trainer" strategy in Montana's regionally based early intervention agencies. The project incorporated four foundations (competency-based educational principles, adult learning guidelines, an ecological approach, and family-centered service delivery) into the following model components: (1) problem-based learning, (2) cooperative learning methods, and (3) peer coaching. The inservice training was also tailored to match the specific desires, resources, and needs of participants (approximately 6 learning facilitators and 80 cooperative learning team members). The Project CLASS model was specifically designed to address rural features. Implementation of Project CLASS occurred in three phases. During Phase 1 a learning facilitator in each agency was identified and these facilitators received training in small groups and established cooperative learning teams within their own agencies. During Phase 2 the facilitators identified their teams' priorities for training, developed and implemented individual training plans. During Phase 3 ongoing training of both facilitators and their home teams continued. Nine appendices which comprise 90% of the document, provide information on training agendas, sample training plans, questionnaire data, and lesson plan training materials. (DB)
