A central California school district has settled a free speech lawsuit brought by a high school junior who was sent home for refusing to change out of T-shirt that read, "Nobody Knows I'm A Lesbian."

The American Civil Liberties Union says the deal approved Tuesday requires the Manteca Unified School District to clarify that students may wear clothing with statements celebrating their cultural identities or supporting classmates' identities.

Taylor Victor and her mother sued two Sierra High School administrators who told the girl in August that her shirt was an improper display of sexuality that violated the school's dress code.

Linnea Nelson of the ACLU says federal courts consistently have ruled that schools cannot prevent students from expressing their personal beliefs unless they pose a threat or significant disruption.
