Secondary international school fees in Buenos Aires (2026/27)

The secondary years are the most expensive stage of an international education in Buenos Aires, and the gap between schools widens as the diploma years approach. Senior tuition typically sits several thousand dollars above the primary rate at the same school, because the timetable broadens into separate sciences, languages and the examined pathway, whether that is the International Baccalaureate Diploma, British A levels or the German Abitur. The figures below are the published senior bands from the Buenos Aires international schools hub, stated in US dollars at prevailing rates and rounded.

The peso is volatile, so the sector benchmarks and often invoices in US dollars. Add roughly 10 to 20 per cent to the headline for enrolment, transport, lunch and the trips programme, which grows in the senior school as residential and subject trips become part of the calendar. Compare this stage against the primary and nursery and preschool pages to see how the bill rises year on year.

Secondary and sixth form fee bands

Figures are headline senior tuition from the schools published schedules on our Buenos Aires hub, in US dollars at prevailing rates and rounded. They exclude enrolment and extras and are not exact quotes for your child year. Confirm current fees directly with each school.

Registration, deposit and other costs

The senior school adds costs that the primary years do not. Examination entry fees for the IB Diploma or the British boards fall due in the final two years, and the residential and subject trips programme is at its fullest in the senior school. Budget the following on top of tuition.

Bands above are indicative ranges, not a single school quote. Always confirm current figures in a school fee schedule before budgeting.

What drives the cost

Curriculum is the clearest driver at senior level. The schools carrying the International Baccalaureate Diploma alongside a national track, led by Lincoln and the British rooted schools, sit at the top of the range because the diploma is resource heavy in the final two years. The French Lycee Jean Mermoz and the German Goethe Schule run their national examined pathways more economically and sit lower, which is why the senior band opens near USD 9,000.

Neighbourhood and campus matter too. The long established schools cluster across the northern suburbs, from La Lucila and Olivos out towards Nordelta, and the schools with the newest senior facilities and the strongest university placement records command the upper end. A sibling discount, where offered, moves a two child senior budget more than any single extra.

Hidden costs parents miss

The examination years are where the surprises land. Entry fees for the diploma or the British boards are billed per candidate, and per subject in some cases, in the final two years, and retakes carry their own charge. Families who arrive mid cycle should also ask whether the school charges a one off senior entry or placement assessment fee.

Transport remains the quiet recurring line, since the senior campuses sit across the spread of the northern suburbs and the bus is a practical necessity for many families. Add the residential trips programme, which is at its most active in the senior school, and the true senior year always costs more than the headline tuition suggests.
