Lately, I’ve been looking at schools for my child and after researching international schools in Spain, I’ve noticed one term that’s impossible to avoid: the IB program. Almost all the better international schools feature it as their gold standard. At first, I was completely clueless—what is it exactly? How is it better than the local Spanish high school curriculum? I’ve spent some time doing my homework, and I’d like to share what I’ve found here with everyone at IB international schools in Spain. I also welcome experienced parents to add their insights and corrections.
Simply put, the IB program isn’t a national curriculum but an independent, globally recognized international education system. It doesn’t emphasize rote memorization but focuses on developing students’ comprehensive skills, such as critical thinking, research abilities, and a global perspective. The full diploma program requires students to study courses from six different subject groups over two years and complete three core components: an Extended Essay (EE), Theory of Knowledge (TOK), and a Creativity, Activity, Service (CAS) project. It sounds challenging, and the demands on students are indeed quite high.

So, what are the real advantages of studying the IB? I think the biggest advantage is its ‘global passport’ nature when applying to universities. Because the IB’s grading standards are globally uniform, universities worldwide, especially top-tier ones in the UK and the US, hold it in very high regard. A good IB score is a significant foot in the door. Moreover, the difficulty and depth of the IB curriculum help students adapt to the pace and thinking style of university studies in advance. It’s said that students who have gone through the IB program generally have more stamina and perform better in the long run at university.
However, the IB isn’t perfect. It demands a very high level of English proficiency and self-directed learning skills. If a child’s foundation is weak, or if they simply don’t enjoy this kind of high-intensity learning model, it can be a very challenging experience. Additionally, schools offering the IB program usually have higher tuition fees. I’ve created a simple table below to compare some of the differences between the IB and the local Spanish Bachillerato curriculum, giving you a more intuitive overview:
| Feature | IB International Baccalaureate | Spanish Bachillerato |
| Curriculum | Globally standardized, interdisciplinary | Spanish national education system, divided into streams (e.g., sciences, humanities) |
| Assessment | Internal assessments + global final exams | School grades + Selectividad/EBAU university entrance exam |
| Language | Usually taught in English or bilingually | Primarily taught in Spanish |
| University Application | Highly recognized by universities worldwide, especially in the UK/US | Mainly for Spanish universities, recognized within the EU |
| Focus | Critical thinking, research skills, holistic education | Knowledge acquisition, preparation for university entrance exams |
Choosing between the IB and Bachillerato really depends on each family’s specific plans and the child’s individual situation. If the clear goal is to attend a top university in the UK or the US, and the child is capable and interested in taking on the challenge, then the IB is definitely a great option worth considering. For instance, parents looking into schools like Kensington School often weigh these factors. On the other hand, if the plan is simply to attend university within Spain or Europe—and you might want to check the latest IB results in Spain to gauge the landscape—then Bachillerato might be a safer and relatively less stressful path. I’m curious, how are you all planning for your children’s education? Let’s talk about it!
