More than 100 students at Arlington's Abingdon Elementary School may be transferred next fall to the Barcroft Elementary School under a proposed change in school attendance boundaries aimed at easing crowding at Abingdon, the county's most populous grade school.

The School Board has scheduled an April 4 vote on Superintendent Charles E. Nunley's proposal. He said Abingdon's projected enrollment for next fall is 698 students, far more than the building can "comfortably house" and a number considered too large for an optimal learning environment.

With 622 pupils enrolled at Abingdon last October, when the official annual attendance was taken, the school at 3035 S. Abingdon St. is the largest of 17 regular grade schools in the county. Three other schools with grade school-age students also have special programs.

Under the proposal, 108 Abingdon students in kindergarten through the sixth grade would be transferred to the county's smallest school, the 223-pupil Barcroft Elementary School at 625 S. Wakefield St. Both schools are in southwestern Arlington.

The attendance area that would be switched from Abingdon to Barcroft is south of Columbia Pike, west of Four Mile Run Drive and north of George Mason Drive. Parts of the area also are bounded by South Columbus, 10th and Frederick streets.

No other boundary changes are proposed. School Board members said they would not favor a suggestion to transfer Abingdon sixth graders to an intermediate school. Abingdon's building advisory committee had offered that proposal as a possible solution to the crowding.
