Throughout the nation, and most notably in Northern California, the incidence of children identified with Autism Spectrum Disorders (ASD) has been on the rapid rise and is reaching epidemic proportions. There is a pressing need to increase the number, quality, and diversity of educators who are fully credentialed and competent to serve students with ASD from diverse ethnic, cultural, and linguistic backgrounds in diverse settings. This 4-year project responds to that need by adding a new program emphasis in ASD to an established Master of Arts and Credential special education programs (K-12/transition) at San Francisco State University. Project Mosaic will be carried out in partnership with local schools, university/medical centers, and community-based programs serving children, families, and adults with ASD. Specialized coursework (4 core methods) and supervised field experiences in diverse, urban settings will be provided over 3 semesters to 80 full-time students, with an emphasis upon recruiting those who have disabilities or who are from underrepresented ethnic, cultural, and linguistic groups. The project will develop specialized research-based curricula and pedagogy that allows 20 candidates each project year to provide services and instruction to students with autism (including core academic areas and English language learning). The project will also evaluate its activities, candidate knowledge and skill, and associated outcomes for students with autism, and will disseminate the program model at the local, state, and national levels.
