My child is nearing school age, and my husband and I have been swamped with the process of choosing a school. After much consideration, we’ve decided the international school system best suits our family’s future plans. But with so many schools, it’s hard to know which is best. While there are methods for [checking international school results], I decided to compile the key data myself. Besides the environment and facilities, academic performance is obviously a key factor. That’s why I’ve spent considerable time collecting and organizing the latest IB scores from some of Spain’s leading international schools to share with other parents navigating this process.

Why are IB Scores Important?
Simply put, the IB program is a globally recognized high school curriculum, and IB scores are a “golden ticket” for applying to top universities worldwide. A school’s average IB score is a strong indicator of its teaching quality and the overall academic level of its students. The maximum score is 45. Generally, a school with an average score of 35 is considered very good, while an average above 38 is truly top-tier.
IB Score Overview for Popular Schools
I’ve gathered data from some well-known schools that have published their scores and put it into a simple table for easy comparison. Keep in mind that scores can fluctuate yearly. Also, some [international schools in Spain] may not publicly release their data, and the grade requirements for international schools can also differ, so this list isn’t exhaustive and should be used as a reference. If you have more accurate information, please share it in the replies below!
| School Name | City | 2023/2024 IB Average Score |
| Runnymede College | Madrid | 40 |
| The English Montessori School | Madrid | 37 |
| Benjamin Franklin International School | Barcelona | 36.5 |
| Sotogrande International School | Cádiz | 36 |
| International College Spain | Madrid | 35 |
Based on the data, Runnymede College in Madrid is an academic powerhouse, with a staggering average score of 40! This is world-class performance. Of course, the tuition fees are also ‘world-class’… my wallet is crying. Benjamin Franklin in Barcelona also delivers consistent results and remains a top choice for many parents.
Choosing a school involves more than just scores. Factors like location, facilities, curriculum specializations, community atmosphere, and alignment with your family’s educational philosophy are all crucial. For example, some schools may not have the highest IB average but offer exceptional programs in art or music. The best way to get a feel for a school is to schedule an in-person visit with your child. I hope this information helps, and I encourage other parents to share their experiences!
