This project will redesign an interdisciplinary teacher preparation program to address a shortage of highly qualified teachers by improving both the quality and the numbers of teachers serving infants, toddlers, and preschool children with mild to severe disabilities, developmental delays, or risk conditions, and their families. Specifically, this program will prepare teachers with a Master's degree in education and endorsement in early childhood special education (ECSE) who can use research-based practices that improve child and family outcomes. It will further prepare teachers majoring in elementary education to work in pre-kindergarten programs for children at risk by enrolling them in nine credits of program coursework to earn an add-on endorsement to teach three and four year olds. The EARLI program may be completed as a two-year Master's degree program for students who already hold a Bachelor's degree in a related field or as a five-year BA/MT program that includes undergraduate studies in psychology and graduate ECSE. EARLI consists of a sequence of integrated coursework and practicum opportunities that allow supervised application of course content in inclusive, diverse settings with target children. Partnerships with parents of children with disabilities, school divisions and agencies serving young children will provide continuous field experiences across the birth to age 5 period. Training priorities include: (a) knowledge of child development and developmentally appropriate practice; (b) use of an appropriate assessment and teaching intervention with young children, including children with English as a second language; (c) family-focused and culturally responsive services; (d) collaborative skills required to work with families and professionals; (e) inclusive service delivery models; and (f) a strong focus on the specialized skills required to teach children with autism and low-incidence intellectual and motor disabilities.
