Strengths

International School of Paris
  • Only full IB continuum (PYP/MYP/DP) school in central Paris, giving an unbroken age-3-to-18 pathway in one institution
  • Triple international accreditation and authorisation: CIS, NEASC and IBO across all three programmes
  • Highly international, language-diverse community of 700+ students from 60+ nationalities with no single nationality dominating
  • Dedicated English as an Additional Language and learning support for newly arrived and non-native English speakers
  • Consistent IB Diploma outcomes with a high bilingual-diploma rate (51 percent for the Class of 2025), reflecting genuine English-French biliteracy
Lycée International de Saint-Germain-en-Laye
  • Free state-funded core tuition — by far the lowest-cost route to a recognised international/bilingual education in the Paris area
  • Fourteen national sections delivering genuine native-language, native-culture instruction toward the Baccalauréat Français International
  • Outstanding documented results — baccalauréat pass rates of 99-100% and a 'mention' (honours) rate above 90%
  • Structured one-year immersion ('Français Spécial') that absorbs non-French-speaking newcomers into the French system
  • Graduates routinely leave trilingual or quadrilingual, with a strong Concours Général and university-placement track record

Trade-offs

International School of Paris
  • !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
Lycée International de Saint-Germain-en-Laye
  • !No boarding — it is a day school across several sites, so it cannot serve families needing residential places
  • !Selective, language-dependent admission means it is not the open-access school its 'free public' label implies
  • !The 'double enseignement' workload (full French curriculum plus the section programme) is heavy and not for every child
  • !Section association fees and one-off entrance charges still apply, and vary confusingly by section, grade and whether an employer pays
