MIT OpenCourseWare and MITx, part of MIT Open Learning, are marking two incredible milestones: 25 years of OpenCourseWare and 10 years of the MITx MicroMasters Program. These initiatives have empowered millions of learners worldwide with free and low-cost access to MIT’s educational resources.

To sustain this impact, we’re challenging 400 people to make a gift to MITx, OpenCourseWare, or MIT Open Learning during the MIT 24-Hour Challenge on March 12. When we reach this goal, $20,000 from a generous alumni donor will be unlocked—helping us continue to innovate to make education accessible for all. Every gift counts!
