In 2006, the National Science Foundation (NSF) began funding the Model Replication Institutions (MRI) program, which sought to improve the quality, availability, and diversity of science, technology, engineering, and mathematics (STEM) education. Faced with pressing national priorities in the STEM fields and chronic gaps in postsecondary achievement, the MRI project identified Minority Serving Institutions (MSIs) as key intermediaries to improve the quality, availability, and diversity of the STEM educational pipeline. This report begins by outlining MRI project activities, providing institutional information about participating campuses, and highlighting campus activities consistent with the components of the Model Institutions of Excellence (MIE) model. Subsequent sections analyze self-reported information from the MRIs regarding their evaluation of successful initiatives to improve STEM education, best practices for adopting and adapting lessons learned, and anticipated next steps in the implementation process. The report aims to disseminate the steps for replicating the MIE model to postsecondary institutions that are seeking to improve excellence and diversity in the STEM pipeline. Appended are: (1) MRI Partners; and (2) MRI Team Assignment: Introductory STEM Data Collection. (Contains 2 boxes, 2 footnotes and 1 figure.)
