MIT Blueprint is a weekend-long virtual learnathon and hackathon for high school students happening virtually this year on February 20-21. Any high school student (grades 9-12) is eligible to apply, and all levels of coding experience are welcome!

Each year, 200 high school students gather for a weekend of learning and building their own computer science project. On the first day (“the learnathon”), students have the opportunity to attend workshops run by MIT students and hear tech talks by organizations. On the second day (“the hackathon”), students will have the opportunity to apply their skills to a project. In addition, this year the organizers are introducing Blueprint Week, which takes place the week before Blueprint and will allow students to form teams and find friends, set up their projects, and speak to different organizations before the weekend even begins. Throughout Blueprint Week and Blueprint itself, students will not only have the opportunity to win fantastic prizes (and swag!), but also have access to experienced mentors and the chance to build connections with education-based organizations. This is a free event. Register by January 25.
