HOUSTON—The Houston school board has voted to ban the use of any race or ethnic group as a school mascot or nickname, starting next school year.

Houston Independent School District trustees enacted the new policy by a 7-0 vote Thursday night, with one member abstaining and one absent. A school district statement says the policy will mean changes in the team names of the Lamar High School Redskins, Westbury High School Rebels, Hamilton Middle School Indians and Welch Middle School Warriors.

Each school will be in charge of choosing its new mascot and retiring its old one.

The Houston school district is the largest in Texas and the seventh-largest in the United States with 282 schools and about 210,000 students.
