Recently, I’ve seen many friends on the forum discussing their children’s schooling, especially showing a lot of interest in international schools but feeling quite confused. My eldest child moved here from China last year, and during our school-hunting phase, I researched almost all the international schools around Madrid. Today, I’m starting this thread to talk about the main curriculum systems in Spanish international schools, hoping to help other parents who are currently struggling with this decision.
The Main Curriculum Systems in International Schools
Spain has a wide variety of international schools, including British, American, German, French, and more. However, in terms of university applications and global recognition, the three most mainstream curriculum systems are the IB, A-Level, and AP. These three systems determine what your child will study during their high school years, how they will be assessed, and which universities they can apply to in the future.

Analysis of Each Curriculum’s Features
To put it simply, each of these three systems has a different focus and is suited for different types of students.
IB Programme: Famously known as an ‘all-rounder pressure cooker.’ It requires students to balance both arts and sciences. In addition to studying courses from six subject groups, they must complete three core components: Theory of Knowledge (TOK), the Extended Essay (EE), and Creativity, Activity, Service (CAS). This system places high demands on a student’s comprehensive abilities, time management skills, and spirit of inquiry. The advantage is its extremely high global recognition, giving a significant edge when applying to top universities in the UK and the US. The downside is the immense academic pressure, making it unsuitable for students who are heavily specialized in certain subjects or have weaker independent learning skills.
A-Level Curriculum: This is the UK’s ‘university entrance exam’ system and is more specialized. Students can choose 3-4 subjects they excel at, based on their interests and future career paths, to study in depth. This model is very friendly to ‘specialist’ students who excel in specific areas, allowing them to delve deep into their strengths. If your child is aiming for universities in the UK or other Commonwealth countries, A-Level is a great choice. The overall workload is generally less than the IB, but the difficulty of individual subjects is not to be underestimated.
AP (Advanced Placement) Courses: These are America’s ‘university-level courses.’ The AP is not a standalone high school curriculum but rather an add-on to the standard American high school program. Students can choose to take any number of AP courses based on their abilities, and good exam scores can even earn them college credit. It offers the most flexibility—a student can take just one or two courses, or challenge themselves with seven or eight. This is why American schools typically offer AP courses, making it the best option for students targeting universities in the United States.
To give you a clearer picture, I’ve put together a simple comparison table:
| Curriculum | Focus | Difficulty & Pressure | Best Suited For |
| IB | Well-rounded, holistic development | ★★★★★ | All-rounders, not specialized, aiming for top global universities |
| A-Level | Specialized, plays to strengths | ★★★★ | Students with clear subject strengths, aiming for Commonwealth universities |
| AP | Flexible, earns university credit | ★★★ | Independent learners aiming for US universities, academically advanced |
When choosing a school and curriculum for your child, there is no ‘best,’ only ‘most suitable.’ It’s crucial to make a comprehensive decision based on your child’s personality, interests, and future plans, which you might discuss during international school interviews. For example, my son is good at sciences but has little interest in history and literature, so forcing him into the IB program would have been very difficult for him. That’s why we ultimately chose a British school that offers the A-Level curriculum. I hope my experience can serve as a reference for you. Everyone is welcome to join the discussion and share their thoughts!
