Association France
France-ioi is a French nonprofit founded in 2004 that publishes free programming and algorithm learning resources for students and teachers from elementary school through university. The site hosts interactive courses, auto-graded exercises, and national competitions that reach about one million young people each year.
Learners can move from first steps in visual programming to competition-level algorithmics. The training platform offers hundreds of mini-lessons and exercises with automatic validation, an online code editor supporting Python, C, C++, Java, JavaScool, Pascal, and OCaml, plus a help forum so students are not stuck for long.
France-ioi also runs Castor Informatique, Algoréa, Alkindi, and French olympiads in informatics and artificial intelligence. It maintains an AI learning path covering how different AI systems work, generative AI usage, and social impact through interactive activities, games, and programming tasks.
