The president of the state Board of Education concedes there's little hope of saving the controversial diversity rule for Minnesota schools. Board members are expected to kill the rule at a meeting today. The proposed rule aims to improve test scores of minority students in schools where they've fallen behind their white classmates. But opponents say the rule tries to do too much and would impose cumbersome mandates on schools. Governor Carlson opposes the rule, and his recent appointment of three new board members appears to ensure its death.
