On Mackworth Island, not far from Portland, the Mackworth Island Preschool Program at the Maine Educational Center for the Deaf and Hard of Hearing/Governor Baxter School for the Deaf (MECDHH/GBSD) helps deaf, hard of hearing, and hearing children flourish. At MECDHH/GBSD, instructors immerse students, 3-5 years old, in American Sign Language (ASL) and spoken English, enrich their sense of Deaf identity, and teach them alongside their hearing peers. This article describes why the program was established and how it caters to each child's individual language needs and communication goals. Further, it discusses the use of informal and formal observational assessments of the children and how daily communication between parents and children fits into the program.
