Recently, I’ve seen discussions in several parent groups about children’s language learning, specifically whether it’s necessary to learn a third language when attending an international school, beyond Spanish and English. My eldest attends an international school here in Madrid, so I have some experience with this. I decided to start this thread to share what I know and hear your thoughts as well.
The Language Environment in International Schools
First off, international schools in Spain offer a truly unique advantage when it comes to the language environment. At my son’s school, more than half of the students are not native Spaniards, and the teachers come from all over the world. Daily communication is a mix of English and Spanish. While the official language of instruction is English, Spanish is a compulsory subject, ensuring that children can integrate into local life. This immersive environment is far more effective than home-schooling or attending tutoring classes. My son now plays with classmates from different countries and is fluent in both English and Spanish. Sometimes he even blurts out words I don’t understand, which he probably picked up from his friends.

Choosing a Third Language
When it comes to the crucial topic of a third language, it really depends on the specific school’s curriculum. Most of the better international schools offer a third language as an elective in secondary school. The most common options are French and German. After all, both languages are widely used in Europe and can be very helpful for future university applications or job prospects. Additionally, some schools also provide Mandarin Chinese classes, which is fantastic for families like ours who want their children to maintain their Chinese language skills. However, the quality of these Chinese courses and the teachers can vary significantly, so it’s best to inquire in detail before enrolling in a school focused on Spanish in international schools.
Here’s a simple breakdown of the common third-language options and some personal thoughts for your reference:
| Language | Advantages | Personal Opinion |
| French | An official UN language, commonly used in Europe, with grammar similar to Spanish. | Seems to be the most popular choice, with plenty of teachers and resources available. |
| German | Germany has a strong economy, with clear advantages in engineering and technology. | Pronunciation can be a challenge for some kids, but mastering it is a huge plus. |
| Mandarin | Helps maintain a connection to their mother tongue and cultural roots; many future opportunities involving China. | School courses might be too basic; extra classes may be needed for in-depth learning. |
| Others | A few schools might offer Italian, Arabic, etc. | These are less common and depend on the child’s interest and the school’s teaching staff. |
Whether to learn a third language, and which one to choose, ultimately comes down to your child’s interests and future plans. If they aren’t interested, forcing them to learn will likely be ineffective and just add to their burden. My personal view is that language is just a tool; it’s meant to serve your child’s future development. If the plan is to stay in Europe long-term, learning French or German is definitely a good move. If you want your child to maintain a connection to their heritage, then Mandarin is the natural choice. What are your thoughts on this?
