Thomas C. Boysen will leave his post as head of the San Diego County Office of Education in June, hoping to find a school-district superintendency, he announced Monday. Boysen has headed the office, which oversees a variety of educational and administrative programs for districts nationwide, since September, 1987.

Boysen, 50, has made the county office a more visible player in state and regional educational reforms. He has pushed efforts to improve student writing, boost drug and alcohol programs, and dispense information about technology and testing--mainly for teachers and administrators in the smaller of the county’s 43 school districts without extensive resources of their own.

The county office has no schools under its direct supervision other than the administration of three juvenile court schools and several independent study programs.

Boysen said Monday that, although he has enjoyed his work at the county office, he would like to return to leadership of a regular school district and will search for such a position between now and the end of his term.
