Join an NCTM Affiliate
There are more than 200 NCTM Affiliates throughout the United States, its territories, and Canada. To search the NCTM Affiliate Directory, select the category and/or state or province from the drop-down menus.
Most Affiliates are organized by geographic area and each Affiliate is assigned an NCTM Membership and Affiliate Relations Committee (MARC) representative. Some Affiliates are organized around a specific topic in mathematics education. These groups are called Affiliates-at-Large.
Some listings include a link to the Affiliate's website.
