Mon Valley School
In 1970, the Pennsylvania State General Assembly created 29 intermediate units across the state of Pennsylvania. Organized as a not-for-profit branch of the Pennsylvania Department of Education, the Allegheny Intermediate Unit (AIU) is the largest of these agencies. The mission of the AIU is to provide educational options and opportunities that maximize achievement for all learners.

Located just a few miles from the city of Pittsburgh in the scenic Waterfront commercial development in Homestead, Pennsylvania, the AIU provides specialized educational services to Allegheny County's 42 suburban school districts and 5 vocational/technical schools.

The AIU employs more than 2,000 employees at 721 sites and operates 12 family centers and three schools for exceptional children. With nearly 130 programs for infants, young children, students, and adults, the AIU receives funding through federal, state, county, and private grants.
