Having moved to Spain a few years ago, my child is now at an age where we need to think about their next school. I’ve been researching all kinds of options: public, private, and international schools. Many friends have recommended British international schools, mentioning their globally-aligned curriculum and the advantages they offer for applying to universities in the UK and the US. So, I’ve spent a good amount of time looking into it and decided to compile what I’ve learned about the exams at British international schools to share with other parents facing the same decisions.
The Core of the British System: GCSE and A-Level
British international schools in Spain follow the UK’s native education system. During their secondary education, students will encounter two crucial public examinations:
GCSE: This is roughly the equivalent of a middle school exit exam. Students typically study for it in Years 10 and 11 before taking a final standardized test. They usually choose 8-10 subjects. Besides compulsory subjects like English, Maths, and Science, there are many electives such as Art, History, and a second foreign language. GCSE results are the foundation for applying to A-Level courses in British international schools.
A-Level: This is the British equivalent of a university entrance exam, taken in Years 12 and 13. This stage is critical, as A-Level results directly determine which universities a student can apply to. Students typically select 3-4 subjects they excel at and that are relevant to their intended university major for in-depth study at schools like the International School of London. For example, if a student wants to study medicine, Chemistry and Biology are almost mandatory.

Key Considerations for Test Prep and Subject Selection
Unlike the single, standardized national exams in some countries, GCSE and A-Level offer a lot of freedom in subject choice. However, this freedom makes the selection process incredibly important. I’ve spoken with a few experienced parents and summarized some key points:
- Interest is the best teacher: A-Level studies are very in-depth. If a child isn’t interested in a subject, they will find it extremely difficult. Therefore, it’s crucial to fully respect your child’s interests and strengths when choosing subjects.
- Plan for university majors in advance: While it’s not necessary to have their entire future mapped out at 16, it’s good to have a general direction. University majors have specific A-Level subject requirements. For example, to study engineering, Maths and Physics are usually mandatory. This information can be found on university websites.
- Be aware of exam board differences: The UK has several exam boards, such as CIE, Edexcel, and AQA. Different schools may work with different boards, leading to slight variations in textbooks and exam styles. Although the core knowledge is largely the same, it’s essential to practice with past papers from the specific exam board during preparation.
Many parents are concerned about the difficulty of the exams. Generally, the complexity of the content isn’t necessarily higher than in other systems, but it places a greater emphasis on a student’s comprehension, analytical, and application skills, rather than rote memorization. The writing requirements, in particular, are very high, posing a significant challenge to language proficiency.
| Exam Stage | Corresponding Age | Number of Courses | Purpose |
| GCSE | 14-16 years old | 8-10 subjects | UK “Middle School Exam”, foundation for A-Level |
| A-Level | 16-18 years old | 3-4 subjects | UK “University Entrance Exam”, key for university applications |
Choosing the British curriculum means opting for a more international educational path. Although the preparation process is demanding, seeing your child engage with independent learning and inquiry-based methods early on feels very rewarding. Are there any other parents here whose children are currently in a British system school? Feel free to join the discussion and share your experiences! For instance, which exam board does your school use? Do you have any useful resources for test prep?
