Enrollment at Hawaii’s public schools is up by 1.1 percent over last school year, an increase of about 2,000 students, the Department of Education said Wednesday.

A total of 185,273 students are enrolled public schools for the 2013-14 year.

That includes 9,797 students in 33 public charter schools — a 2.1 percent increase — and 173,658 students in 255 DOE schools, a 1 percent increase over last year.

The DOE attributed the increase to a large number of births in 2008 and more students staying in public schools.

Oahu’s Leeward District, which includes 42 schools, saw the most growth statewide, with an increase of 721 students, or a 2 percent increase to 37,114 students.

Campbell High in West Oahu remains the largest high school, with 2,821 students, followed by Waipahu (2,450) and Mililani (2,445) high schools. Mililani Middle is the largest intermediate school by enrollment, with 1,743 students, followed by Kapolei Middle (1,464) and Waipahu Intermediate (1,314). And August Ahrens is the largest elementary school, with 1,427 students, followed by Ewa Beach’s Holomua (1,383) and Kapolei (1,136) elementary schools.

Among charter schools, Kamaile Academy in Waianae has the largest enrollment, with 899 students in grades kindergarten to 12th grade.

The Hawaii Association of Independent Schools’ annual report on private school enrollment is scheduled to be released later this year.
