The Allegheny Intermediate Unit, also known as the AIU, is a regional public education agency and a crucial part of Pennsylvania's public education system. Our caring staff of educators, administrators and support staff provide specialized services to Allegheny County's suburban school districts as well as non-public, charter and vocational-technical schools. Our agency is a liaison with the Pennsylvania Department of Education and we proudly operate three schools for exceptional children, 11 family centers and about 130 programs for children, adults and families. The AIU's Services Guide contains a comprehensive listing of these programs. The AIU is one of 29 intermediate units across the state.
