Join our movement to make an impact

For the past 10 years, CK-12 has been on a mission to provide free access to high quality educational content in multiple modalities, and you have been part of our success. Thank you!

CK-12 has no subscription, no advertising and no licensing to schools or users. Everything on CK-12 is 100% free. And we intend to keep it that way. At the same time, we are committed to useful content, with high quality, measurable impact.
Here’s how you can help. My vision for CK-12 is to help every child in the world access a high quality education. Not just basic content, but allow for every student and teacher to customize the material to learn in his or her own way. Our team passionately believes in our mission and has proven that a small team of 30 can make a huge difference in K-12 education. We’ve worked hard to keep production costs low and our impact high.

Achieving our mission and reaching even more children could be accelerated with your support.

We appreciate your support at any level – $5, $10, $20, or whatever you can. Help us accelerate our impact and help every student in the world. These donations will be used for more work from our team to you.

Thank you for joining our mission! Each learner’s success is accelerated with your help!
