Summer Session Information

Summer session at the University of Wyoming offers a chance for students to complete course work in a more flexible timeframe for available courses. Courses can vary in length as well as start and end times, which provides students flexibility during the summer months. There are also field opportunities and other options that are not as easily done through the Fall and Spring terms. This page will show the dates and deadlines for the summer session. When registering for summer term courses, be sure to check the Instructor/Meeting Times in the course description to ensure you are able to attend during the course dates.
