Having just arrived in Spain, I’ve been looking at schools for my child, and the process of researching international schools has been quite overwhelming. I’ve noticed many friends asking about SEK International Schools, which seem to be very well-known among expatriate parent communities. I’ve done some homework and wanted to share my findings on where these schools stand in Spain and what their rankings are really like, hoping to start a good discussion.

First, it’s important to know that Spain, unlike some other countries, doesn’t have an official, nationwide ‘international school ranking’ system. Many of the rankings we see, like the annual ‘100 Best Schools’ lists from publications like Forbes or the El Mundo newspaper, are comprehensive. They include private, semi-private (concertado), and international schools, so they aren’t exclusively for international institutions. The schools under the SEK Group, such as SEK-El Castillo and SEK-Ciudalcampo in Madrid, are regulars on these lists, often placing near the top. This shows that locally in Spain, SEK’s educational quality and reputation are widely recognized, placing them in the top tier.
So why is there some ambiguity about its rankings? I think the main reason is that SEK is an educational group with six schools in Spain, plus campuses in Dublin, France, and Qatar. Each campus varies in size, facilities, focus, and student body. For instance, the El Castillo campus in Madrid is historic with outstanding facilities, while the Ciudalcampo campus is known for its excellent sports programs. Therefore, you can’t generalize with a single ranking for all campuses. It’s best to research the specific campus you’re interested in; for an example, see this discussion on [SEK-Castillo].
SEK’s Strengths and Some Personal Thoughts
SEK’s biggest strength is its highly developed IB curriculum. The complete pathway from PYP and MYP to DP is a huge draw for families hoping their children will apply to universities in Europe or the US. Furthermore, [SEK International Schools] place a strong emphasis on technology and innovative education, and their facilities are updated frequently—something you can clearly see when visiting the schools.
However, I’ve also heard other perspectives. Some parents feel the schools have a slightly strong commercial atmosphere, and their tuition fees are on the higher end for international schools. Additionally, due to the schools’ reputation, they receive many applications, making admission, especially for lower grades, very competitive. Below is a comparison I’ve compiled of the two main Madrid campuses for your reference:
| Campus | Features | Best for Students Who… |
| SEK-El Castillo | Oldest campus, most complete facilities, strong academic atmosphere | Value comprehensive development and academic achievement |
| SEK-Ciudalcampo | Top-tier sports facilities, beautiful natural surroundings, activity-rich | Love sports and seek well-rounded development |
SEK is definitely one of Spain’s top international schools, but it may not be the perfect fit for every child. I highly recommend attending a school Open Day, speaking with admissions officers, and getting a feel for the atmosphere to see if it aligns with your family’s educational philosophy and your child’s personality. Does anyone have more inside information on [SEK International School tuition fees]? For instance, are there any pitfalls to watch out for in the application process? Feel free to join the discussion!
