Founded in 2020 and already at 950+ students, TASIS Portugal is the fastest-growing international school in the Lisbon area. Part of the globally respected TASIS Foundation network — the original TASIS in Switzerland was the first American international school in Europe, founded in 1956 by M. Crist Fleming.
TASIS Portugal offers a distinctive curriculum combining Core Knowledge (structured content approach), Singapore Math (the world's highest-performing maths methodology), Next Generation Science Standards, and unique enrichment subjects including coding, chess, violin, leadership and rhetoric from the earliest years. Students progress through Cambridge IGCSE in Grades 9–10, then the IB Diploma in Grades 11–12.
Every class maintains a 1:8 teacher-to-student ratio — the lowest of any major international school in the Lisbon region. Pre-K through Grade 4 classes have two fully qualified full-time teachers plus specialist teachers. Lunch and two daily snacks are included in tuition — a rare benefit among Lisbon international schools.
The purpose-built modern campus at Quinta da Beloura features state-of-the-art classrooms, science laboratories, athletic fields and play spaces. The school has grown from zero to 950+ students in just five years, supported by a strong and active TASIS Parents Association.
“The school has been incredibly welcoming to our family. The teachers go above and beyond to support expat children.”

What families tell us — the things the school's own website won't say
TASIS Portugal is the newest of the major Lisbon international schools — founded in 2020, it has no long track record for IB or IGCSE results yet. We strongly recommend visiting the campus and speaking to current parents before committing.
