Republican mayoral candidate Hal Heiner‘s latest TV ad says “It’s time to end the failed student assignment plan.” In the spot (watch here), Heiner makes suggestions for improving Jefferson County Public Schools, such as offering teachers incentives to work in poor-performing schools. In a debate earlier this month, Heiner said he wanted the mayor to be “directly involved in improving education.”

At the same debate, Democratic candidate Greg Fischer said he wants to involve parents more in schools, but didn’t say he wants to end the assignment plan.

Independent Jackie Green favors ending the assignment plan, but said he would make neighborhoods diverse by spreading public housing across the city.
