School districts across Ohio will be able to authorize teachers, principals and other staff to carry firearms into classrooms this fall after only 24 hours of training now that Republican Gov. Mike DeWine signed House Bill 99 on June 13. Previously 700 hours of training were required. The 24 hour training includes four scenario-based training hours, plus a maximum of 20 hours for first aid training, history of school shootings and reunification education. It includes only 2 hours of hands- on training with a gun.
