A bill awaiting action by Arizona Gov. Jan Brewer targets the ethnic studies program at the Tucson Unified School District.
Proponents say the program helps students connect to the curriculum, but the state schools chief says it promotes "ethnic chauvinism."
The bill would prohibit courses that are designed primarily for students of a particular race, that advocate ethnic solidarity or promote resentment toward a certain race.
Arizona's Superintendent of Public Instruction, Republican Tom Horne, has been trying for years to pass the bill.
He began fighting the program after learning that Hispanic civil rights activist Dolores Huerta told high school students that "Republicans hate Latinos."
District officials deny that their program promotes resentment.
