(AP) — Lincoln officials are thinking about requiring some middle school students to wear photo IDs on lanyards around their necks.

The ID system has been required at district high schools since 2007. The IDs help administrators ensure the teenagers in the school buildings are supposed to be there. The IDs also serve as lunch tickets and passes at football games and other school events.

District security director Joe Wright says he wants to test the system at Irving Middle School and another middle school he hasn’t yet selected.

He says the company that makes the IDs will provide free badges for two middle schools for a year. Wright says that would give the district an opportunity to determine whether expansion is worth the expense.
