Lately, I’ve seen many discussions on forums about choosing schools for children in Madrid, especially international schools. My child has been attending SEK-Castillo for almost two years, so I thought I’d share some firsthand, unofficial insights as a reference for parents navigating this decision. This is purely my personal take, intended as a casual share.
We initially chose SEK-Castillo primarily for its IB curriculum and the overall environment. The school is located in Villanueva de la Cañada, an affluent suburb northwest of Madrid. It’s a bit of a distance from the city center, but the trade-off is a massive campus and a wonderful natural setting. The school building resembles a small castle, with plenty of greenery and fresh air, making it feel like my child is going on an outing every day. For families who value open space and a good environment, this is a significant plus.

Curriculum and Teachers
The school offers the complete IB curriculum from early childhood through high school. The PYP (Primary Years Programme) in the elementary stage is very much about ‘learning through play.’ The teachers are excellent at guiding students and nurturing their curiosity. My child, who used to be quite introverted, now proactively comes home to share various school projects, and their hands-on and presentation skills have improved significantly. While most of the teachers are Spanish, their English proficiency is excellent, and there are also many international teachers. The faculty seems quite stable, communication with them is smooth, and they provide a good level of individual attention to each student.
About Tuition Fees and Application
Regarding the tuition fees, a key concern for many, SEK-Castillo is in the upper-mid range among Madrid’s international schools. It’s not the most expensive, but it’s not cheap either. The annual fees vary by grade level, so it’s best to check the official website for the latest figures to avoid any inaccuracies from my side. The application process usually involves submitting documents, an interview, and sometimes a simple entrance assessment. They seem to place importance on whether a family’s educational philosophy aligns with the school’s. To give you a general idea, here’s a basic cost breakdown, and you can find more information about [SEK International Schools]:
| Item | Description |
| Matrícula | An annual registration fee, required to reserve a student’s place. |
| Escolaridad | The main tuition fee, paid monthly or quarterly. |
| Comedor | Optional school lunch service; most students use it. |
| Ruta | Optional school bus service, with fees based on the route distance. |

Overall, our experience here has been very positive. My child is happy, the academics are rigorous, and there are plenty of sports and arts activities. The main drawback might be its location, which can be inconvenient for those living in the city center, so commute time is a factor to consider. Additionally, while it is an international school, Spanish students make up the majority of the student body. So, if you’re looking for a fully immersive English environment, you might want to compare other schools.
