Our History

The Coordinator's Office of Student Activities (COSA) was established in the fall of 2013 to oversee and manage all school social events. Tiegerman staff volunteer on the COSA committee, helping to facilitate programs like the Big Brother/Big Sister Mentorship, Intramurals, and the Student Leadership Council. All COSA initiatives are designed to provide hands-on experiences that complement students' academic and vocational training. The Leadership Program, in particular, allows students to apply the skills and knowledge gained in their life skills, character development, and vocational classes. COSA actively encourages student participation in school events.
