Each syllabus identifies the assessment method that will be used to demonstrate student mastery of the desired learning outcomes for that course. Before teaching a course, faculty should review the syllabus to understand how the program learning outcomes will be evaluated. Once the course is complete, this form is used by the instructor to report how well students demonstrated mastery of those course learning (and by extension, program learning) outcomes.
