Hour of Code: the largest learning event in history

Computer science is a foundation for every student. Join us to help millions of new learners start with one Hour of Code. Sign up at hourofcode.com!

What is the Hour of Code? A one-hour activity. Students of all ages can choose from a variety of self-guided tutorials, for kindergarten and up. Tutorials work on any modern browser, tablet, smartphone, or even with no computer at all.

Code.org’s own tutorials feature the Minecraft and Star Wars tutorials, as well as Disney’s Frozen, Scrat from Ice Age, Angry Birds, and Plants vs. Zombies. 

The Hour of Code is a spark to keep learning computer science. Once students see what they create right before their eyes, they’re empowered to keep going. No experience needed from teachers and students.

It is a global movement with more than 100 million learners in 180 countries. Anyone, anywhere can organize an Hour of Code event. Tutorials are available in 40 languages.

Why computer science? Every 21st-century student should have the opportunity to take part in creating technology that’s changing our world. The basics help nurture creativity and problem-solving skills, and prepare students for any future career. But most schools still don’t teach computer science.

About Code.org

Code.org launched in 2013 as a bootstrapped project of co-founders Ali and Hadi Partovi. Their initial work was a video that became #1 on YouTube for a day, and 15,000 schools reached out to them for help. Since then, they've expanded to build a full organization supporting a worldwide movement. Code.org believes that a quality computer science education should be available to every child, not just a lucky few.

To support their goal, Code.org does work across the education spectrum: designing our own courses or partnering with others, training teachers, partnering with large school districts, helping change government policies, expanding internationally via partnerships, and marketing to break stereotypes.

This work builds upon decades of effort, by countless organizations and individuals who have helped establish, fund, and spread computer science education.
