AMITYVILLE - Teachers and school administrators are doing the math to determine what they could expect under the 2012-13 spending plan Gov. Andrew Cuomo (D-N.Y.) unveiled yesterday. The governor is touting a proposed increase across the state in school aid for next year. However, educators on Long Island aren't celebrating just yet, because they say numbers on paper and dollars in their districts are two different things. Under the proposal, the Amityville School District would get about 4 percent more in state aid. The superintendent says after two years of significant cuts, the increase would only put them back where they started, and he says the district would still have to lay off teachers and other staff. Cuomo's budget plan calls for boosting aid to Long Island schools by 2.7 percent on average. However, he also wants schools to pick up some expenses previously paid for by the state. Some local educators say they feel Long Island is unfairly viewed as the wealthy part of the state, and is therefore less eligible for aid that's desperately needed.Cuomo unveils state budget with no tax hikesCuomo to schools: New teacher evaluations or no more aidGov.
