I’ve recently seen many discussions on forums about sending children to school in Spain, especially for high school. It seems the information is a bit scattered and the topic can be quite complex. My own child is approaching this stage, so I’ve spent a lot of time researching international schools around Madrid and Barcelona. Today, I’m sharing what I’ve learned, hoping it can help other parents in the same boat.
Which Curriculum to Choose? IB, A-Level, or AP?
In Spain’s international schools, there are three main curricula: IB, A-Level, and AP. Each has a different focus and directly impacts a child’s future university applications and learning experience. Understanding their differences is the first step in choosing a school.
IB
This system places a strong emphasis on students’ holistic development and inquiry skills, requiring a balance between arts and sciences with no room for subject specialization. In addition to the six subject groups, there are three core requirements: Theory of Knowledge (TOK), the Extended Essay (EE), and Creativity, Activity, Service (CAS).
- Pros: It has the highest global recognition, especially favored by top universities in the UK and the US. It significantly develops a student’s comprehensive abilities, critical thinking, and academic writing skills.
- Cons: It is the most difficult and comes with immense academic pressure. It demands high levels of English proficiency and time management skills, making it unsuitable for students who heavily favor certain subjects over others.
A-Level
This is the UK’s national curriculum, where students typically choose 3-4 of their strongest or most interesting subjects for in-depth study over two years. It is an ideal path for students with clear goals and distinct academic strengths, allowing them to focus on what they do best while families can plan for the associated [international school fees].
- Pros: It allows students to focus on their strengths. It provides a strong advantage when applying to universities in the Commonwealth, as well as some in Europe and the US.
- Cons: The breadth of knowledge is narrower compared to the IB, and it’s less comprehensive in developing a student’s overall skills.
AP
AP is not a complete high school curriculum, but rather a set of university-level courses that supplement an American high school curriculum. Students can take AP courses and exams during high school, and high scores can earn them college credits.
- Pros: Course selection is flexible; students can choose any number of subjects based on their abilities and interests. They are a significant advantage when applying to top US universities.
- Cons: It’s less structured than IB and A-Level and must be taken alongside a US high school diploma program. AP scores alone cannot serve as a high school diploma from a Spanish international school.
To make the comparison clearer, I’ve created a simple table:
| Feature | IBDP | A-Level | AP |
| Structure | 6 subject groups + 3 core elements | 3-4 self-selected subjects | Flexible; no fixed structure |
| Difficulty | ★★★★★ | ★★★★ | ★★★☆ |
| Best Suited For | Well-rounded, all-around students | Students with clear goals and subject strengths | Students aiming for US universities with academic capacity to spare |
| University Path | Top universities worldwide | UK, Commonwealth, & European universities | US universities |

Finally, a few personal thoughts. Choosing a school is about more than just rankings and tuition fees; the most important thing is to find a match for your child’s personality, strengths, and future plans. Some famous [Spanish international schools] might not be the right fit if your child struggles to keep up, as the immense pressure can be counterproductive. The best approach is to identify one or two target curricula, then book visits to several schools’ Open Days. Take your child with you to experience the school’s atmosphere and chat with teachers and current students. This is far more effective than reading any number of brochures. I hope everyone finds the perfect school for their child!
