Trade-offs
- !Ends at Grade 8 — there is no high school and no secondary-exit credential; families must transfer for grades 9–12
- !Because it is PreK–8, there are no exit-exam results or university-placement data to publish — outcomes must be judged on programme quality
- !Accreditation marks (WASC, CAIS) are cited from a third-party summary and were not confirmed on the school's own reachable pages — verify directly
- !Does not publish a current total enrollment, so scale and cohort sizes cannot be confirmed
- !Not an IB or Cambridge school — families specifically seeking those pathways are not served
- !High tuition places it among the most expensive independent options in the city
- !The school does not publish current total enrollment, class sizes, or graduate placement data on its site
- !French-forward model may not suit families seeking a purely English-medium environment
