Course Leaf Section Scheduler (CLSS)
Course Leaf Section Scheduler (CLSS) is Northwestern’s primary academic scheduling tool. CLSS updates SES through the first week of each academic term. This gives class schedulers control of their schedules from initial planning through the end of student registration.
