AUSTIN, Texas (AP) -- Texas Governor Rick Perry is indicating he's OK with a school district's decision to allow teachers and staff to carry guns in the classroom.

The Harrold Independent School District approved the measure last year.

It requires a teacher carrying a gun to school to be properly licensed. They also must have training in crisis management and hostile situations, and use ammunition that minimizes the risk of ricochet.

The superintendent of the district near the Oklahoma border argues the sheriff's office is a half-hour away, leaving students and teachers without protection. The district is small, with just 110 students.

In Texas, individual school districts have the option to decide if teachers can carry guns in the classroom. Asked if other school districts should follow suit, Perry says it's up to them to decide.
