A legislative proposal for requiring annual training for teachers who carry guns inside Indiana schools was scuttled amid a disagreement over whether it infringed on gun rights.

The state Senate approved the bill this month, but a House committee chairman said Monday that he would not be taking any action on the proposal ahead of this week’s deadline for advancing it.

The proposal specifies a 40-hour training program for teachers volunteering to be armed. It included 20 hours of scenario-based training and six hours of marksmanship, along with reviews about lawful use of force and personality screening, followed by 16 hours of additional training each year.

The training bill, which cleared the Senate on a 42-7 vote, also faced opposition from the gun control group Moms Demand Action as a step toward “normalizing” a high-risk strategy of arming teachers.

A similar training bill failed last year.
