All Cadets attend formation at the start and end of the school day. Formations last roughly 10-15 minutes each and serve four primary purposes.

1. Attendance and Punctuality:
Morning and afternoon
formations are a good way to account for all students' presence on the school grounds. Attendance is taken by the Corps leadership every day and a status is issued to the Commandant.

2. Public Affairs:
Morning and afternoon formation give the CORPS a public forum for the distribution of critical information, from both a military and non-military standpoint.

3. Leadership Development:
Morning and afternoon formations are a way for Cadets to develop as leaders. All aspects of formation are executed by the student body. From the adjutant issuing school news to sergeants inspecting for proper uniforms to the battalion commander issuing an order of "present arms" as the flag is raised to the reveille each morning, everything is handled by Cadets.

4. Camaraderie and Friendship:
Morning and afternoon formations help develop a sense of pride, camaraderie and friendship among the CORPS of Cadets: a unique experience of being a Cadet at Benedictine.
