Our Academic Year mostly follows the NYC Department of Education. We begin on the first Thursday after Labor Day in September, and finish in late June. When NYC Public Schools are closed (snow day, etc.) we are also closed. Below are downloadable copies of our current academic calendars.

Riverdale Montessori School also has a summer program that runs for 7 weeks, from early July to mid August. For incoming students, this is a great way to get to know their classmates and teachers. The 2023 Summer Program will run from July 5-August 18.
