I’ve been looking into schools for my child recently, and it’s been quite overwhelming. Especially when looking at international schools in Madrid and Barcelona, the variety of curricula—IB, A-Level, the American AP, and more—can make your head spin. I guess many newcomers to Spain face the same confusion. I’ve compiled my findings here to get the ball rolling, hoping it helps others. Experienced parents, please feel free to add your insights!

A Showdown of Mainstream Curricula
Currently, the most mainstream systems in Spain’s international schools are three major ones: IB, the British A-Level, and the American curriculum. These three differ significantly in their educational philosophies, course structures, and assessment methods, directly impacting a child’s future university applications and learning experience at [Spanish international schools].
The IB System
This system is very popular right now, known for its ‘holistic education’ approach, emphasizing the development of well-rounded skills and an international perspective. The IB Diploma Programme (high school level) requires students to choose one subject from each of the six academic groups and complete three core components: Theory of Knowledge (TOK), the Extended Essay (EE), and Creativity, Activity, Service (CAS). In simple terms, it prevents over-specialization, requiring students to study both arts and sciences, write research papers, and engage in community activities. It demands strong comprehensive abilities from students and can be quite demanding, but it’s highly recognized by universities worldwide. It’s especially suitable for students aiming for top global universities who haven’t yet decided on a specific major.
The A-Level System
This is the British high school international school curriculum, and its main characteristic is ‘specialization’. Students typically choose 3-4 subjects they are best at or most interested in and study them in-depth over two years. This model is perfect for students who already have a clear career path or excel in specific subjects. For example, if a child aims to study medicine, they can focus their efforts on subjects like Chemistry and Biology. A-Level results provide a significant advantage when applying to universities in the Commonwealth, and they are now increasingly recognized by American and other European universities as well. Compared to IB, its scope is narrower, but the depth of study is greater.
The American System & AP
The American curriculum is more flexible, usually based on a credit system. Advanced Placement (AP) courses are the icing on the cake, functioning as college-level introductory courses. High school students can take AP courses in subjects that interest them. If they pass the exams, they not only showcase their academic abilities in university applications but can even earn college credits. This offers a huge advantage for students interested in an American-style international school curriculum and aiming for US universities. American education also places a strong emphasis on individuality and creativity, with a generally more relaxed and dynamic classroom atmosphere.
To give you a clearer picture, here’s a simple comparison table:
| Feature | IB System | A-Level System | American & AP System |
| Educational Goal | Holistic development, comprehensive skills | In-depth specialization, academic focus | Flexibility, personal development |
| Course Selection | 6 subject groups + 3 core components | 3-4 self-selected subjects | Credit-based, optional AP courses |
| Best for Students Who | Are well-rounded, not over-specialized | Have clear goals, excel in specific subjects | Aim for US universities, are self-motivated |
| Application Advantage | Top universities worldwide | Commonwealth universities | US universities |
There’s no absolute ‘best’ system, only the ‘best fit’. When choosing a school for your child, it’s crucial to consider their personality, interests, and future plans.
