Innovating in the present.
What is 42?
Artificial intelligence, cybersecurity, software development, data, the cloud and quantum computing are transforming the way we live and work. At 42, you don’t just come to learn how to code: you come to discover how the technology that will shape the future works, how it is designed, trained and developed.
Here, you don’t just memorise theory or sit through traditional lessons. Youlearn by doing, solving real-world challenges and working in teams with other students, through an innovative model based on peer learning that develops both technical skills and key abilities for any professional career: independence, creativity, resilience, adaptability to change and collaboration.
What’s more, the course is 100% free, thanks to the support of the Telefónica Foundation, and is open to anyone of legal age, with no prior experience in programming or computing required.
It’s not just us saying this. In 2026, 42 was recognised as Europe’s most innovative university by the WURI ranking, an international accolade for an educational model that breaks with convention to train the professionals needed by the digital economy.
If you’re looking for a different kind of education—one that’s connected to cutting-edge technologies and designed to prepare those who will shape the future—then 42 Madrid Fundación Telefónica is the place for you.

Frequently asked questions
We’ve compiled some doubts, questions, and existential crises on a handy FAQ page.
Not at all. You don’t need to have any programming skills to join us and succeed at 42.
At 42 we offer a study methodology that challenges our students with projects with increasing complexity. Each problem is unique and requires you to think differently alongside the other people studying on the campus.
Once you’ve passed both of the online tests, you’ll be able to pre-register for the piscine, the 26-day immersive selection period on the campus.
The dates will be announced throughout the year by email and on our social media.
This is the last step before you become a student at 42 and you reach it after you’ve passed the two previous online tests. This is an in-person challenge lasting 26 days in a row during which you’ll undertake daily projects giving you the chance to gain solid foundations in C language while you learn to work alongside the other candidates.
We don’t have any selection quotas at 42. There’s no fixed number of applicants for selection. However, we temporarily reserve 30% of the places to allow women to register throughout a longer period of time.
No, it isn’t necessary either during the piscine or after you become a student. We have 300 iMacs, which are more than enough to cater for the candidates and students. Although you can use your own laptop, it’s advisable to use the ones on the campus, particularly during the Piscine.
The Piscine is demanding and requires spending numerous hours programming and working with the other candidates throughout the 26 consecutive days that it lasts. Although it isn’t impossible to complete it while you work, we recommend making this period a priority.
Not getting through the Piscine stage means that 42 might not be for you, at least for the time being. The Piscine is designed to enable you and 42 to find out whether this educational model is right for both of us. You’ll have to wait for 300 days to re-apply for the Piscine if you don’t get through it the first time.
The start of the studies is a continuation of the Piscine; we always recommend not interrupting this learning process. If you know that you aren’t going to enrol on the campus after the selection process, it would be advisable to give your place to someone who’s eager to start.
