International School of Paris

The International School of Paris (ISP) was founded in 1964 and sits across three campuses in central Paris's 16th arrondissement (Ranelagh, Cortambert and Beethoven). It is an English-medium, non-profit day school enrolling roughly 700 students from over 60 nationalities, with French taught alongside English throughout. It markets itself as the first and only three-programme IB World School in Paris, running the IB Primary Years Programme (Nursery to Grade 5), Middle Years Programme (Grades 6-10) and Diploma Programme (Grades 11-12).

The school's defining feature is its continuous IB pathway from age 3 to 18 within a single institution, a structure relatively rare even among international schools. It is accredited by the Council of International Schools (CIS) and the New England Association of Schools and Colleges (NEASC), and authorised by the International Baccalaureate Organization for all three programmes. Dedicated English as an Additional Language and learning support provision back the international, language-diverse intake.

Academically, ISP reports solid IB Diploma outcomes: a 90 percent pass rate and an average of 32 points for the Class of 2025, with 26 percent of students scoring 36 or above and 51 percent qualifying for the bilingual diploma. Prior cohorts ran slightly higher (an average of 33.3 points for the Class of 2024). These are respectable rather than elite figures, consistent with an academically broad, inclusive international intake rather than a selective hothouse.

Fees for 2026-27 run from EUR 25,500 in the Nursery to Pre-Kindergarten band up to EUR 39,000 in Grades 10-12, placing ISP firmly in the premium central-Paris international tier. The school is day-only, with no boarding, so it serves resident families and relocating expatriates rather than international boarders.
