Welcome to The Critical Thinking Consortium

TC² is a non-profit organization of Partner groups and Individual Members.

Each year we support many thousands of educators through a range of face-to-face, online and print resources and services developed around a classroom-proven approach to embedding critical thinking. Our aim is to help students learn to think and think to learn.

What is the difference between partnership and membership?

Partners are organizations like schools and school districts who have joined TC². Educational leaders within these groups often work with TC² staff to provide professional learning programs for their teachers. Employees of these groups enjoy benefits such as free access to our three main online resource collections, discounts on all TC² resources and access to the library of professional resources.

Is my school or district a Partner?

Check out our list of current Partners.

If your district, school or faculty is not a TC² partner, you can obtain the benefits of partnership by becoming an Individual Member.

Please contact our administrator if you have any questions.
