Outline:
NOTE: The outline provides suggested time allotments for presentations and activities based on an 8am start time and 4pm end time. Instructors have the latitude to adjust the allotments commensurate with actual start times, the knowledge and experience in the cohort, and the class size. For example, larger classes may require more time for group work and “report outs”.
