Learning Outcomes Attachment for Career/Technical Courses
Faculty regularly review the extent to which the course and program learning outcomes identified in a
course syllabus are being attained by students who complete the course. 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.
