This study examined California's efforts to foster preservice preparation of early intervention assistants through a certificate program offered by community colleges, the Community College Personnel Preparation Project. Community colleges enrolled in the project must meet a series of requirements, including infusing early intervention assistant competencies into coursework, adding early intervention field experiences, and drawing on the experience of community partners and advisory committee members. The study examined data from the inception of the project in 1998 through 2006. Forty community colleges participated during this time, representing 37 percent of the community colleges in the state. Data were gathered from the quarterly reports required of the participating colleges, faculty mentor monthly reports, and administrative annual reports. Reported findings include: (1) Colleges could develop preservice training programs for early intervention assistants that meet requirements such as those for awarding a Chancellor's certificate, although not all colleges that participated in the project were successful despite receiving state funding for startup expenses: (2) Participating colleges implemented many common features, though not all took the same approach; and (3) Some of the approaches colleges took to meet the project requirements differed by project outcome. The study provides an overview of data on the evolving national picture and the West Region states. Specific early intervention training is valuable preparation for a workforce that can serve infants and toddlers with special needs. Those seeking to promote a cadre of early intervention assistants and paraprofessionals prepared at the community college level may find value in examining California's efforts. Three appendixes are included: (1) Methodology; (2) Demographics of Colleges that Participated in the Community College Personnel Preparation Project; and (3) College Expectations and Proposed Timelines for the Chancellor's Certificate.
