Arlington School Superintendent Charles E. Nunley gave the County School Board three school closing plans yesterday for implementation in the 1984-85 school year that include changes in attendance boundaries.

Nunley said he will not recommend one plan until after public hearings are held next month. The board is expected to act in May.

Each of the plans, prompted largely by declining enrollment, calls for closing Claremont and Reed elementary schools and relocating the Clay-Langston adult education programs. Depending on which plan the board approves, Swanson and Kenmore intermediate schools and Yorktown High School could be closed, as well as another elementary school.

Selection of schools to close was based on building size, enrollment, and, in many cases, location, according to Nunley. One of the plans suggests closing Tuckahoe Elementary, an air-conditioned building with both a gymnasium and multipurpose room, because of its "marketability for leasing due to its location." The school, at 6550 N. 26th St., is near Lee Highway and Rte. 66.

Last night, the board ordered Nunley to produce fuller explanations for some of the school closing selections.

Earlier this month, Nunley irritated School Board members when he said it was too early to determine future boundaries. Board members then directed him to include them, and the plans released yesterday carry suggestions for extending attendance boundary lines generally in an east-west direction to provide a "better balance in enrollment and racial and ethnic diversity."

The plans would also provide either for intermediate and senior high students to attend schools within the same attendance districts or exempt from transfers students already enrolled in the 10th, 11th and 12th grades at the beginning of the 1984 school year.

Last fall, the board directed Nunley to prepare closing plans based on two grade-grouping configurations. The first, the 6-2-4 plan currently used in the system, would place kindergarten through sixth grade in elementary schools, seventh and eighth grades in intermediate schools and grades nine through 12 in high school. Nunley said he favors that configuration over another, known as the k-7 and 8-12 plan.

Nunley's first two plans are based on maintaining the 6-2-4 configuration. Option I also calls for maintaining the three high schools; closing one of the county's four intermediate schools, probably Swanson, and closing Barcroft and Tuckahoe elementary schools. Option II calls for closing one high school, probably Yorktown, and two intermediate schools, Swanson and either Kenmore or Thomas Jefferson.

Option III calls for establishing 10 K-7 elementary schools and three 8-12 intermediate/high schools by maintaining all senior high schools; closing Ashlawn, Barcroft, Nottingham, Glencarlyn, Jamestown and Tuckahoe elementary schools, and closing Thomas Jefferson Intermediate School. The plan would also add a seventh grade to Drew Model alternative school.
