Teachers in one part of the US state of Texas are to be allowed to carry concealed firearms when the new school term opens this month.
The school superintendent in Harrold district said the move was intended to protect staff and pupils should there be any gun attacks on its sole campus.
Teachers would have to undertake crisis management training first, the superintendent, David Thweatt, said.
In recent years the US has seen a number of fatal school shootings.
Trustees had approved the policy and parents had not objected, Mr Thweatt said.
