MIU IV provides services through a mutually agreed written arrangement (MAWA) with the state of Pennsylvania for all districts in Butler, Lawrence, and Mercer counties, except for Farrell School District. MIU IV provides a continuum of early intervention services from child find to direct services. This continuum includes supportive and supplemental services in a variety of preschool settings, specialized early intervention services in combination with other programs, home, specialized early intervention classrooms or more restrictive placements in approved private schools. Early intervention programs may also be provided through contracted services or in conjunction with Head Start programs.

Auxiliary related services are provided when needed and defined in the Individual Education Plan (IEP). These services might include assistive technology, audiology, case management, social work, physical therapy, occupational therapy, health-related services in the classroom, parent education, family services and transportation.

The IU operates several early intervention classrooms in each county, and partners with many Head Start programs, community preschools and early care and education programs supporting children and families in the tri-county area.
