House Bill 13-1089 (PDF), which would have encouraged teachers in Colorado to misrepresent the scientific status of evolution and climate change, was rejected by a 7-6 vote in the House Committee on Education on February 4, 2013.

The committee also voted 7-6 to postpone further consideration of the bill indefinitely.

Otherwise a typical instance of the "academic freedom" strategy for undermining the integrity of science education, HB 13-1089 was unusual in targeting higher education as well as K-12 education.

The primary sponsors of HB 13-1089 were Stephen Humphrey (R-District 48) in the House and Scott Renfroe (R-District 13) in the Senate — in Colorado, bills in either house of the legislature will have a sponsor in the other house.

Among those testifying for the bill was a representative of the Discovery Institute, who claimed that his organization helped to draft the bill.

Among those testifying against the bill were representatives of the Colorado Association of School Boards, the Colorado Education Association, and the Colorado Alliance for Environmental Education.
