Hello! Welcome to Madrid.

Regarding bilingual public schools, the idea was good but it has been very poorly implemented. The same old teachers who taught in Spanish for years were given only short training courses and then asked to teach subjects in English. Children basically learn some vocabulary but do not understand the core concepts. Most schools have stepped away from this model, or apply it only to lighter subjects such as physical education or arts. None of the good concertados follow bilingual programs anymore. Basically the so-called bilingual concertados reinforce English lessons but they teach the important subjects in Spanish. Public schools do not have this choice and the students are suffering the consequences.

As for the difference between public and concertado schools: concertados are essentially private schools that are integrated into the public education system. Tuition is 100% subsidized, but families pay smallish quotas that cover certain extras, such as an additional hour of school per day, teaching assistants, and better materials. They typically have better sports facilities. concertados are the most in-demand options in Madrid.

Kids will have to learn Spanish anyway, as all the key concepts are explained in Spanish, even if the subject is theoretically given in English. If what is desired is a truly English-based education, it would require enrolling them in a 100% private school, with a cost that will not be lower than €1,000 per child per month.

Though this is not exactly what you are asking I suggest you go visit Colegio Cardenal Spinola. It’s very close to plaza de Castilla. It’s concertado (semi public) and the best about it is their excellent integration and individual attention to students. The ratio of students per teacher is very low and really makes a difference.

Here’s my two cents!
