Two key proposals are moving forward in the Rochester City School District. The first, involves tougher lead testing in city schools; only five of the citys 52 schools are lead-free. That measure, which has been sent to an audit committee, would force lead testing to happen on a regular basis, instead of only when theres a renovation. The second proposal is a plan to introduce an African-American curriculum in the district. That plan has been met with some controversy. It is set to be voted on at Thursdays board meeting.
