CourseLeaf Section Scheduler (CLSS) 


CLSS is our online scheduling tool that allows us to build, edit, and validate the course schedule while also being able to analyze, and report on class scheduling information. Starting with FS19's schedule, CLSS will be the primary tool used for the course schedule.
