The following were among actions taken at the Oct. 21 meeting of the District of Columbia Board of Education. For more information, call 724-4289.

SUPERINTENDENT SEARCH -- The board voted unanimously to form a search committee to find a superintendent to replace Floretta McKenzie, who will leave the post in February to head her own educational consulting firm in the District.

The committee, which the board will choose at a later date, will consist of the board's student representative, Kwanza Jones, six community members and six board members.

The committee will be charged with screening candidates and recommending no more than 10 before March 30, 1988. The board will sponsor a public hearing on the search at 6 p.m. Nov. 4 at Dunbar Senior High School, 1341 New Jersey Ave. NW.

DRESS CODE -- Board member Linda Cropp (Ward 4) said at the end of the meeting that she may schedule public hearings to discuss the possibility of requiring uniforms or instituting a dress code in the school system.

Burrville Elementary, at Division Avenue and Hayes Street NE, began requiring its 340 students to wear uniforms beginning this fall. The idea had been proposed by principal Walter Henry to save parents money and to lessen fashion competition in the schools. The boys' package consisted of three dark blue trousers, three light blue shirts, a sweater and three pairs of socks for $107. The girls' package consisted of two blue plaid jumpers, three blouses, a sweater and three pairs of socks for $80. Financial aid was available from the school.

"I think, as we explore such a controversial issue, we should look at what has happened at Burrville," Cropp said.

LIQUOR LICENSE APPLICATIONS -- McKenzie reported that the school system had registered objections to the liquor licenses applications of two stores that are near elementary schools.

The stores are Marie's Market, 346 Elm St. NW, which is near Gage-Eckington Elementary at Third and Elm Streets NW; and Park's Variety, 3023 Martin Luther King Jr. Ave. SE, which is near Martin Luther King Jr. Elementary at Sixth Street and Alabama Avenue SE.

Board regulations require that a protest be filed with the Alcoholic Beverage Control Board against any applications for liquor licenses from businesses that are within 400 feet of a school. A protest also may be filed in cases where neighbors, the Parent-Teacher Association or board members fear there would be an adverse impact on school children.
