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
- !Premium fees up to EUR 39,000/year put it out of reach for many families
- !Day-only with no boarding, limiting it to families resident in or relocating to Paris
- !IB averages (around 32) are solid but not elite, below the most selective international schools
- !Split across three separate central-Paris campuses rather than a single unified site
