The following were among actions taken at the May 28 meeting of the Prince George's County Board of Education. For more information, call 952-6000.

CHILD CARE -- The board voted unanimously to authorize Superintendent John A. Murphy to begin before- and after-school day care programs in 15 additional elementary schools this fall.

The programs will be patterned after extended day care programs now serving students in some of the county's magnet schools. They will provide recreational and educational activities for elementary school children from 7 a.m. until school begins and from after school until 6 p.m.

The programs will be offered at 14 nonmagnet elementary schools scattered throughout the county and Middleton Valley Elementary School, a magnet school without a day care program. Registration will begin June 11, after the program is advertised in the designated schools.

The board's decision to implement care programs was based upon the recommendation of a school task force. The board hopes to develop programs in all county elementary schools within several years, board spokesman Brian Porter said.

The program is designed to be self-supporting. Children of school employes and community residents are eligible for the program at a cost of $35 per child per week, with a sliding scale for parents of more than one child enrolled in the program. No transfers will be permitted from other schools for the sole purpose of entering a before- and after-school program.

MULTICULTURAL EDUCATION -- The board voted unanimously to adopt a resolution that Murphy assign a task force to examine the potential for multicultural education throughout the county school system.

The resolution, introduced May 14 by members Catherine Burch and Sarah Johnson, calls for a community-wide committee to study how best to put multicultural experiences into county education programs in the 1988-89 school year. The committee will be chosen within the next month, and will present recommendations for teaching strategies to increase county students' understanding of the similarities and differences of people, nations and cultures of the world.

HIGH SCHOOL HONORS -- This year's 44 valedictorians and salutatorians from the county's 20 high schools were recognized along with their parents in a special two-hour reception hosted by school board members before the meeting.
