A Thammasat University academic proposes school designs to delay an attacker and give people time to escape or hide: perimeter fences that are hard to climb, cluster layouts with space between buildings, zigzag corridors, hiding spaces, and escape routes. He asks the Education Ministry to add attack-evacuation drills to the curriculum alongside fire drills, and asks for safety criteria in the building act. These are research proposals, not current rules. For a school owner or private-school operator, there is nothing to act on yet, but future building-code or drill requirements could affect renovation plans.
