And it was all because of how the mother was dressed.
Joselyn Lewis says she was trying to enroll her 15-year-old into a school in Houston last Monday.
She says she was refused entry because her t-shirt dress was too short, and her headscarf was not up to the dress code.
The mother says she thought the school administrator telling her this maybe thought she was a student.
The police were called when Lewis refused to leave.
She vowed to wear different clothing when she returned the next day to register her daughter for school.
