My kid is starting high school soon, so my husband and I have been deep-diving into all the school options in Madrid. Public, private, and semi-private—each type has its own pros and cons. After looking into all of them, we feel that a semi-private school, perhaps like those in the rankings of private high schools in Spain, might be a great compromise. So, I’m starting this thread to share my thoughts and would love to hear from other parents with experience in this area!
What is a Semi-Private School (Colegio Concertado)?
Simply put, a semi-private school (colegio concertado) is a “government-subsidized private school.” The facilities and some of the staff may belong to a private institution, but because it receives government funding, it must follow the public school curriculum and its fees are much lower than those of purely private schools. You can think of it as having the characteristics of a private school in terms of facilities and management, while aligning with public schools on core curriculum and cost. Many middle-class Spanish families opt for this type of school.

Analysis of Pros and Cons
From my research, the pros and cons of semi-private schools are quite clear:
- Pros: Excellent value for money
! This is their biggest advantage. You get better facilities, more dedicated teachers, and smaller class sizes than in public schools, but at a cost far lower than purely private schools. Additionally, many semi-private schools have a religious background, which often means they place a strong emphasis on student conduct and discipline, leading to a generally positive school environment.
- Cons: First, there are
limited spots. Because they are popular, there are many applicants. For reputable schools, admission is often based on a point system and sometimes even a lottery. Secondly, while the tuition is low, various extra fees for uniforms, lunches, extracurricular activities, and textbooks can add up to a significant amount. Also, schools with a strong religious affiliation may have a more traditional approach to teaching values.
To make it clearer, I’ve created a simple comparison table for your reference:
| School Type | Tuition | Facilities | Staff & Management | Admission Difficulty |
| Public | Free | Average, varies greatly | Follows state standards | Based on catchment area points |
| Semi-Private | Low | Generally good | Stricter, more dedicated teachers | High, points + lottery |
| Purely Private | Expensive | Excellent | Flexible, elite-focused | School’s own admission process |
If you want your child to study in a well-managed environment with a good atmosphere and decent facilities, but without the high cost of a purely private school, then a semi-private school is definitely worth considering. It’s also a good idea to look into available high school subsidies
. Before applying, be sure to visit the school’s open days, talk to teachers and students, and get a real feel for the atmosphere. We have now shortlisted two schools and are preparing to submit our applications. Wish us luck! And good luck to all the other parents out there going through the school selection process
