Enrollment at Island public schools increased slightly for the 2013-2014 school year, according to data collected on Oct. 1. This is the fourth year in a row that enrollment at the six Island schools has held relatively steady, reversing a nine-year trend of decreasing enrollment numbers.

According to the school census data, a total of 2,075 students are enrolled at the schools this year — 18 more than were recorded during a census taken in October of 2012. There are 1,075 boys and 1,000 girls enrolled.

The student population at the high school is identical to last year, with 682 students. Growth in student populations came at the elementary level, with small increases spread among four of the elementary schools.

The largest elementary school is Oak Bluffs, with 380 students in kindergarten through eighth grade. Edgartown serves 361 students; Tisbury, 316 and West Tisbury, 274. Chilmark School is the smallest, with 62 students enrolled in kindergarten through fifth grade.

The charter school in West Tisbury serves 180 students this year in kindergarten through 12th grades, the same number as last year and the maximum allowed enrolled at the school.

The largest grade Island-wide is the freshman class at the regional high school with 195 students, up 30 students from last year.

Eleven students attend residential programs off-Island that are paid for by the school district.
