North Shore Long Island School Districts: Graduation, Attendance and Size

NYSED publishes a report card for each district, and this page puts eight of them in one table and then looks closely at North Shore Central, the district behind Sea Cliff and Glen Head. It is one of several decisions in the buying guide.

How the eight districts compare on 2024-25 state data

North Shore Central: the district behind Sea Cliff and Glen Head

North Shore Central School District serves Glenwood Landing, Glen Head, Sea Cliff, Old Brookville and parts of Greenvale and Roslyn Harbor. It was formed in 1953 from the smaller Sea Cliff, Glen Head and Glenwood Landing districts. NYSED lists five schools: Glen Head Elementary, Glenwood Landing Elementary, North Shore Middle School, North Shore Senior High School and Sea Cliff Elementary.

Its single high school opened in 1957. Sea Cliff School was built in 1912 and expanded in 1926, and Glen Head School dates to 1924. A series of major renovations and additions to all five buildings was performed in 2000. The biggest piece replaced the north and south wings of Sea Cliff School. Voters in the 1970s repeatedly defeated proposals to demolish and replace that building.

NYSED reports $44,643 in expenditures per pupil for the district. The same profile lists the district’s accountability support model as Local Support and Improvement.

Test results: what proficient means

NYSED counts a student as proficient when the student scores performance level 3 or 4 on state tests. On North Shore’s profile, 86% of grade 3 students are proficient in English language arts. Grade 8 shows 72% in English and 57% in math.

A 98% graduation rate and a 57% grade 8 math result sit on the same report card. Chronic absenteeism, meaning students absent 10 percent or more of the days they were enrolled, is 13% in the high school and 9.6% in grades 1-8.

Grades 3-8 results in all eight districts

Each cell is the share of students who reached performance level 3 or 4 on the 2024-25 state test. English language arts first, then math.
