ACE, which was founded by the New England Center for Children and is used primarily in individualized instructional environments, is a structured program grounded in the principles of Applied Behavioral Analysis.Lifeways classrooms also include small and whole group instructional methodologies in which students are engaging in Core Curriculum Standards through access skills addressed by direct instructional programming.The program uses a life skills curriculum to build student independence in activities of daily living. Skills targeted include those needed daily across home and work environments as well as during leisure activities. These skills are addressed in a variety of settings and include cooking, vocational experiences, personal hygiene, and community-based instruction.
