If your institution is like most others in the United States, half of your STEM majors leave STEM or your institution within 2 years of matriculation. If that sounds like a problem you should be addressing, attend this hands-on workshop to start working on solutions! We’ll begin with an overview of surveys you can easily implement to assess key psychosocial variables in your undergraduates and understand why your STEM majors are leaving. We’ll then engage in a stimulating discussion about changes you can make based on these assessments to close the loop and boost your STEM retention by 50%.
