Indiana teachers who carry guns in schools would need to undergo annual training under a proposal advancing in the state Legislature.

In a Tuesday vote by the State Senate that went 42-7 in favor of the bill, it specifies a 40-hour training program for teachers volunteering to be armed, followed by 16 hours of additional training each year.

Supporters of the bill urged for the proposal to pass because teachers can be armed with permission of their school districts but the state does not have any training requirements.

The proposal specifies that the training program must include 20 hours of scenario-based training and six hours of marksmanship.
