The Mathematics Teacher Education Partnership (MTEP) was a networked improvement community (NIC) of secondary mathematics teacher preparation programs across the country that worked collaboratively to redesign secondary mathematics teacher preparation programs based on its updated Guiding Principles for Secondary Mathematics Teacher Preparation and the Association of Mathematics Teacher Educators (AMTE) Standards for Preparing Teachers of Mathematics.

First organized in 2011, MTEP produced a substantial body of knowledge addressing common problems of practice in secondary mathematics teacher preparation. In 2020, a new iteration of the network titled MTEP 2.0 was launched, with a focus on supporting the efforts of local secondary mathematics teacher preparation programs to transform their efforts using the NIC design.
