Prince George's County Public Schools

Prince George's County, Maryland

After the School Development Program’s initial success in New Haven, two districts involved in major desegregation cases adopted the model: Benton Harbor, Michigan (Berry v. School District of Benton Harbor) and Prince George’s County, Maryland (Milliken v. Bradley II).

The Comer School Development Program was introduced in 10 Milliken II elementary schools in Prince George’s County Public Schools in 1985 as their model for school improvement and development, and with a special focus upon improving parent and family participation in schools deemed “difficult to desegregate.”

Since 1986, the Comer Process has been used in other elementary and secondary schools in the county, by selection of the model by school administrators, school teams, community groups, or by direction of the central office.
