This article directs attention to partnership models, such as the North Dakota State University Graduate Student-University-School Collaborative (NDSU GrSUS) project, that are replacing one-time summer courses and workshops as vehicles for improving science, technology, engineering, and math (STEM) education in the United States. This project involves placing graduate students in the STEM disciplines in year-long fellowships with practicing middle or high school science and mathematics teachers. One of the goals of the project, now in its fourth year of operation, is ''increased collaboration between NDSU scientists and mathematicians and area middle and high schools.''
