The Fairfax County School Board last night announced the layoffs of eight full-time and 95 part-time teachers, all at the secondary and intermediate levels, at the end of this school year.

The layoffs will come mostly among teachers of art, social science and vocational classes. No teachers in math or science will be affected.

A year ago 28 full-time and 104 part-time teachers were notified they would be laid off, but most were rehired in the fall.

State law requires informing teachers of layoffs by April 15. In previous years, school administrators notified all teachers who might be laid off, including those they expected to rehire by September, and all, including those later rehired, were able to collect unemployment benefits during the summer.

This year, only those not expected to be rehired will receive notifications, a procedure that school officials say will save unemployment benefit costs and reduce what Assistant Superintendent R. Warren Eisenhower called the "human agony" of uncertainty.

In other action, the board postponed discussion of a proposed pilot Naval ROTC program at Herndon High School. Board Chairman Ann Kahn said action on the proposal would be delayed to allow for community discussion. Although Arlington, Montgomery and Prince George's counties already have ROTC programs, the voluntary Herndon course would be the first in Fairfax County.
