These are the numbers the school gave the U.S. Department of Education for the 2023-24 school year, published in July 2026. The survey counts students in kindergarten to grade 12, not pre-K. Enrollment and staffing move every year, so ask the school for today’s figures. Where this comes from. Something wrong? Tell us and we will fix it.
