The Technical Work Group is a subcommittee of the Adaptive Management Work Group, and is chaired by one of the TWG committee members selected by a vote of the committee. The responsibilities of the TWG are to develop criteria and standards for monitoring and research programs; provide periodic review and updates; develop resource management questions for the design of monitoring and research by the Grand Canyon Monitoring and Research Center, and provide information, as necessary, for preparing annual resource reports and other reports, as required for the AMWG.

The TWG is comprised of technical representatives from each organization represented in the AMWG, with the exception of two members from the National Park Service representing the Grand Canyon National Park and the Glen Canyon Recreational Area, and one representative from the U.S. Geological Survey. TWG members are appointed by the member agencies or interests represented on the AMWG.
