At COT Education, we are working to lower the cost of education for all learners.  A registered 501(c)(3) corporation, our mission is to create and support programs that increase access to affordable lifelong learning for everyone. We are a group of passionate volunteers who provide thought leadership to the open education community and maintain College Open Textbooks, one of the premier resources for finding open, affordable, college-level learning materials. Join us as we work to ensure that everyone has access to quality, affordable, lifelong learning.


The mission of COT Education is to create and support programs that increase access to affordable lifelong learning for everyone.

We are currently focused on the two-year college level, a crucial entry point to higher education for millions of students. We are building products and services to help ensure that everyone has an opportunity to pursue quality, affordable higher education.



COT Education, a direct descendant of College Open Textbooks, is today an independent 501(c)(3) organization.

2008 College Open Textbooks is founded to help two-year college educators find affordable alternatives to expensive, commercially published textbooks. Open textbooks (whose content is licensed under an open copyright and made freely available)  are a powerful alternative and have helped millions of students lower the cost of education. Today, the College Open Textbooks site offers over 850 open and/or affordable textbooks in over 20 academic subject areas.

2010 College Open Textbooks is subsumed by Open Doors Group, an umbrella organization whose charter expanded to support a wide range of open education initiatives. A project of the Silicon Valley Education Foundation, and supported by a generous grant from the William and Flora Hewlett Foundation, Open Doors Group took a leading role in advocating for expanded access to education. It was active in training, consulting, and connecting educators with the opportunities afforded by open education and Open Educational Resources. Today, Open Doors Group has focused its mission on improving education through business models, professional development, and technology. COT Education and Open Doors Group maintain a mutually supporting relationship as we pursue our respective missions.

2014 COT Education is spun off from Open Doors Group as an independent 501(c)(3) organization.  Our goals are  thought leadership to the rapidly accelerating open-education movement and to build on the success of College Open Textbooks in delivering exceptional services to students and educators. COT Education is an organization of passionate volunteers dedicated to lowering the cost of education for all learners.
