A Delaware School District has now become the first in the region to buy what it calls an unconventional kind of classroom protection.
The bulletproof whiteboard is made by a company named Hardwire and is designed to operate as an everyday classroom dry erase board.
But the company says it also doubles as a last line of protection in an active shooter situation.
Officials at the Colonial School District in New Castle County have announced the purchase of 121 of the boards, which they say were inspired by the shootings Sandy Hook Elementary.
