Republican Ohio Gov. Mike DeWine on Monday signed a bill allowing teachers and education staff to carry guns in schools with just 24 hours of training.

The new law drastically reduces the amount of training that staffers across the state need to undergo before they’re allowed to carry firearms on school grounds.

Previously, teachers and staff in Ohio were required to have 700 hours of training — in line with peace officer requirements — before school boards could grant them approval to be armed on school grounds.

DeWine said the measure, called House Bill 99, had been in the works since last year — but the recent mass shooting in Uvalde, Texas that left 19 elementary school kids and two teachers dead “certainly increased the urgency to enact it.”

The new law, which will still require individuals to be approved by school boards, is more practical than the previous standard, the governor argued.
