An Oklahoma charter school is changing its dress code after inciting criticism for telling a 7-year-old girl that her dreadlocks violated the school's policy.

Tiana Parker and her parents say she was summoned last month to the administrator's office at the Deborah Brown Community School in Tulsa and told her hairstyle was against school policy. Her parents later decided to move Tiana to another school.

But Monday night, the school board voted to change its policy that had banned dreadlocks, afros and other hairstyles.

The new policy says only that students and parents are responsible for personal hygiene, and that administrators have the right to contact parents or guardians regarding such issues. There are no specifications on hair styles.

The school says nearly 100 percent of its students are African-American.
