Margiotta said Thursday in Greensboro that the board is committed to the switch to neighborhood schools. He told the Greater Raleigh Chamber of Commerce its members should cooperate with the school board.
He says the old busing program failed to help the economically disadvantaged students. He also says many parents didn't like having children reassigned to different schools each year.
Supporters of the diversity policy have led heated protests, with more than two dozen arrested for disrupting school board meetings.
An NAACP complaint is prompting a review team to look at the accreditation of Wake high schools.
Margiotta also confirmed that he is leaning toward not running for reelection next. Although he has not made a decision, he said he is 95 percent sure he won't run. His school board district includes parts of Cary, Apex, and Holly Springs.
