CONFLICT: official 401,700–789,300 differs >10% from previously recorded 401,700–650,700 (was [O]); official preferred. Official-site discrepancy noted 2026-10-06: Chunk cites the 2025/26 table topping out at G9 650,700; the official 2026-2027 table extends to G11-12 at 789,300 (~21% above the chunk's top figure — new academic year and added grade rows).

Google reviews

Google removed ratings and reviews for K-12 schools worldwide in April 2025, so no live Google rating exists for this school — and we don't display placeholder scores. For parent opinion, ask the school for its parent association and its latest inspection or accreditation reports.
