The Houston school district board has given preliminary approval to a policy that would prohibit the use of mascots considered offensive or culturally insensitive.

Local reports indicate the policy calls on schools to show respect and sensitivity in nicknames and mascots. The use of any race or ethnic group will be prohibited. Preliminary approval was given at a board meeting Thursday.

While the new policy does not refer to specific nicknames or types of mascot, the school district has said that three campuses _ the Lamar High School Redskins, Hamilton Middle School Indians and Welch Middle School Warriors _ would be affected.

A fourth school, Westbury High, might have to drop the use of Rebel, even though connections to the Confederacy were eliminated more than two decades ago.
