A new policy at a high school requiring students to wear identification badges has prompted some parents to complain and students to protest the move as an infringement on their rights.

The badges, which are identical to the IDs students have always been required to carry and use to check out library books at Poplar Bluff High School (search), are now required to be worn on campus during school hours.

"We need to be able to identify people without having to walk up to them and ask if they are a student or a teacher," said Sheldon Tyler, an assistant principal at the high school in this town of 16,700 about 150 miles south of St. Louis.

Some students have put stickers on their badges in protest — a policy the superintendent has permitted as an exercise in free speech. One father, John Durbin, withdrew his two daughters until he can talk to the school board about the policy.

"I believe this country needs security. But if we put ourselves in a cage just to be safe, what kind of life do we have? There is a fine line there, and I wonder if we are beginning to cross it," Durbin said.

Durbin said the policy change should have been decided by the school board instead of school administrators. He and other parents plan to give the school board a petition at the next meeting on Nov. 18 asking them to eliminate the policy.
