The National Science Teachers Association (NSTA), in collaboration with the National Council of Teachers of Mathematics (NCTM), established the STEM Teacher Ambassador project. The project is identifying teachers who have received a Presidential Award for Excellence in Mathematics and Science Teaching (PAEMST) to serve as STEM Teacher Ambassadors, advocating for STEM education in their district and state. In the two-year span of the project, 10 teachers will be selected as Ambassadors annually with the ultimate goal of establishing a national network of teacher leaders who will serve as advocates in every state. Horizon Research, Inc. serves as the external evaluator for this project.
