The Center for Teaching Thinking (CTT) is an educational service organization providing workshops, staff development programs, and resources for schools and colleges interested in incorporating an emphasis on critical and creative thinking into their curriculum. CTT has been in operation since 1992 when it became an independent non-profit organization. CTT has now established itself as a world leader in this field. One important specialty of CTT is infusing the teaching of thinking into content instruction. CTT actively promotes instruction in schools and colleges that helps to develop students’ thinking skills, intellectual habits of mind, and sensitivity to the need for good thinking on the job, in professional work, and in the course of our everyday lives. This is accomplished by an active program in which we work with and provide resources for educators at all levels using well-researched techniques for staff-development. CTT conducts such programs year round. One important message that CTT-trained educators bring to their students is that they can become quality thinkers no matter what their social, ethnic, or economic backgrounds are. Hence, CTT works at every level of the educational spectrum.
