Before you visit

NCES Private School Search — the federal record this listing comes from (school ID A0502339).
Ask your state education department whether the school is approved to serve students placed by school districts, and how it is licensed or accredited.
Find your state's Parent Training and Information Center — free help with IEPs and placements.

Figures are what the school reported for fall 2023. The survey does not verify licensing, accreditation, staff qualifications or the disabilities a school serves; ask the school. Schools can move, merge or close after a survey.

Reported data, not a review. Figures are what the school told NCES for fall 2023. Confirm state approval and accreditation, and read our guide to placement and the IEP before you sign a tuition contract.
