Fairfax County school officials have failed to meet half their goals for hiring and promoting more women or minorities into jobs in which their numbers are under-represented, the School Board was told last night.

In a report covering the period from November 1984 through October, school officials said they made progress toward equity, but did not meet goals for hiring minorities in clerical, teaching, professional/technical, and some administrative jobs.

The school system also failed to meet the goals it set for itself in hiring women maintenance workers and promoting woman custodians.

The system achieved its goals in hiring male clerical workers, woman administrators, hiring minorities for some administrative jobs, promoting minorities into higher-level maintenance jobs and recruiting more men and minorities for bus driver and food service jobs.

The annual goals were established in an affirmative action plan adopted by the School Board in July 1984. Its goals were designed to promote equal employment opportunity and to provide students with a range of role models to use in selecting their own careers.

Currently, 55.6 percent of county school administrators are men and 44.4 percent are women. There are fewer women -- 26.7 percent -- in the top administrative jobs.

In county school clerical jobs, however, women are more than 97 percent of the work force. Women and minorities hold many of the county custodial jobs -- 47.3 percent and 69 percent, respectively -- but fewer of the supervisory jobs -- 32.1 percent for women, 62.9 percent for minorities.

All but a few aides and food service workers are women. All but a few maintenance and trades workers are men.

"We've made progress -- maybe not to the full extent we'd like, but progress has been made," R. Warren Eisenhower, assistant superintendent for personnel, told the board. Frank Francois, the minority representative to the School Board, said the county should look harder for teacher and clerical job applicants from minority groups. Eisenhower promised to do so.

At the same meeting, Preston M. Royster, chairman of the county NAACP branch, criticized the schools for what he called an inadequate response to lagging achievement by minority students.

School Board Chairman Mary E. Collier told Royster the county had a "firm commitment" to improve minority achievement, but it cannot be done overnight.
