St. Peter's School, Barcelona

In Brief

St. Peter's is the strongest IB-only choice in Barcelona for families who want the full PYP-MYP-Diploma continuum in English, with consistently high results and a warm community feel. The Les Corts location is excellent; the fee structure rewards early entry through the lifetime enrolment fee.

Founded in 1964 as the first English-medium international school in Barcelona, St. Peter's is the only school in the city offering the complete IB continuum - PYP, MYP, and Diploma - entirely in English. Around 634 students from ages 1 to 18; IB Diploma average 35.3 in 2025, fourth in Spain. Forbes named it the number one school in Spain in 2021. The Les Corts campus on Carrer Eduard Toldrà is well-placed for families across the western residential districts.

The school's curriculum goes beyond the standard IB framework: it has built what it calls an 'Exponential Science' pillar integrating blockchain, nanoscience, neuroscience, and AI into secondary-level study. It holds Cambridge International accreditation alongside IB World School status (all three programmes). A science laboratory for children aged 0-6 is the only one of its kind in Catalonia. Parent reviews are strongly positive - 4.6 out of 5 on ISD across 14 reviews, with families consistently describing a close, supportive community.

Fee structure: annual tuition runs from EUR 9,450 (Foundation F1-F2) to EUR 18,690 (IB Diploma). There is no application fee. The lifetime enrolment fee - paid once on first entry - varies by stage: EUR 3,800 for Nursery, EUR 7,200 for PYP Year 1-5. This means families who join at Foundation pay significantly less in lifetime fees than those who join at secondary. Annual registration is EUR 1,800. The ISD listing shows fees up to EUR 22,250 for the current academic year; confirm the exact figure directly with admissions.
