Student start or end dates vary by the audience shown in the official calendar.
Niskayuna’s two middle schools serve successive grade groups. In 2026–27, Birchwood, Craig, Glencliff, Hillside, and Rosendale remain K–5 schools, all sixth graders attend Van Antwerp, and seventh and eighth graders attend Iroquois. Students then enter Niskayuna High School in ninth grade. The sixth-to-seventh-grade transition includes a change between the two middle-school campuses.
The district’s published plan schedules a further change for 2027–28: fifth grade would move to Van Antwerp, making that school grades 5–6 and the elementary schools K–4. Iroquois would continue to serve grades 7–8.
