GCSEs and A-Levels in Lisbon: The British Exam Route

For families committed to the British system, the IGCSE-then-A-Level pathway offers a clear, globally recognised route through secondary school and into university. Several Lisbon schools provide it. This guide explains how the British exam route works in Portugal, which schools offer it and how the qualifications support university entry — useful for any internationally mobile family considering the British pathway.

IGCSE vs GCSE

A frequent point of confusion: British international schools, in Lisbon and elsewhere, almost always offer the IGCSE (International GCSE) rather than the UK domestic GCSE. The IGCSE was designed for international schools, is offered by Cambridge and Pearson Edexcel, and is treated as equivalent to the GCSE by universities and employers worldwide. For practical purposes, a child taking IGCSEs in Lisbon is on the same footing as a GCSE student in Britain.

IGCSEs are typically taken across Years 10 and 11 (around ages 14–16), with students sitting a spread of subjects including English, mathematics, sciences, languages and humanities.

The A-Level stage

A-Levels follow at sixth form, usually over two years (around ages 16–18). Students typically specialise in three or four subjects, allowing depth and early focus — a key difference from the broader IB Diploma. A-Levels remain the classic route into UK universities and are accepted across the world.

Which Lisbon schools offer the British exam route?

School	Area	Provision
St. Julian's School	Carcavelos	IGCSE and A-Level (alongside IB and a Portuguese section)
The British School of Lisbon	Central / Restelo	Cambridge IGCSE and A-Level
Astoria International School	Alvalade	British curriculum to age 18
The Lisboan International School	Central Lisbon	Cambridge / IGCSE pathway (opened 2025; IB Diploma planned later)
Greene's College Estoril	Estoril	Specialist IGCSE and A-Level tutorial preparation

Provision differs by school and changes as newer schools build out their senior years, so confirm the exact sixth-form offer — some schools pair A-Levels with, or offer instead, the IB Diploma. Our British schools in Lisbon guide profiles these schools, and IB schools in Lisbon covers the alternative.

How the route supports university entry

A-Level grades feed directly into university applications. For UK universities, students apply through UCAS using predicted and then final A-Level grades. For universities elsewhere — including in the United States, Europe and beyond — A-Levels are a well-understood qualification, though some destinations have additional requirements (such as standardised tests for some US universities). Our university admissions guide explains the application routes in detail.

A student taking the British route in Lisbon should keep an eye on the bigger picture: subject choices at A-Level can open or close university courses, so good university guidance from the school matters.
