Trade-offs
- !Day school only - no boarding option for families needing residential placement
- !BSO inspection yields a compliance 'standards met' outcome, not a graded distinction band
- !Single curriculum pathway (British GCSE/A-Level) with no IB or IGCSE alternative
- !High fees (up to ~EUR 31,498) place it at the premium end of the Paris market
- !Not an IB or Cambridge school and runs no externally examined diploma, so no published exam or IB-score outcomes exist to benchmark
- !Provision currently stops at Grade 8 (age 14), so families needing through-to-18 continuity must transfer for high school
- !Premium fees with a notably higher first-year cost driven by one-time enrolment and capital fees
- !No boarding and a single west-Paris (Neuilly) location, limiting catchment to nearby families
