Colorado Education Association

The Colorado Education Association is the state's largest teachers union, representing nearly 40,000 K-12 teachers, education support professionals, higher education faculty, and retired educators. It serves as the state affiliate of the National Education Association, the largest labor union in the United States.

The organization appears on the 2026 ballot as a primary backer of Proposition NN, a legislatively referred measure that would raise the state's Taxpayer's Bill of Rights (TABOR) revenue cap to increase funding for K-12 public education. The union is leading the "Yes for Colorado Kids" campaign in support of the measure. The organization has publicly stated that the proposition would allow the state to retain revenue it already collects to boost educator pay, reduce class sizes, and address underfunding without raising taxes.

The union frequently engages in political advocacy and ballot measure campaigns related to education funding and policy. In 2026, the organization also endorsed Amendment 87, which would establish a graduated income tax to fund education and healthcare, and opposed Proposition 134, an initiative regarding sex requirements for school sports. The union regularly endorses candidates for state and local offices through its political action committee, the Colorado Fund for Children and Public Education.
