A long-projected revenue chill is beginning to bite in a number of states, putting pressure on education policymakers to defend existing programs--and, in some cases, forcing them to prepare for the worst if budget cuts become a reality. The causes vary, from slack property-tax receipts in Florida to a chronically sluggish economy in Michigan. But the result is the same: financial uncertainty as school districts head into the 2007-2008 school year and begin planning in earnest for the next budget cycle. Complicating that picture is worry on the part of some economists--reinforced by the continued national housing slump and a gloomy September 7 jobs report from the U.S. Department of Labor--that the worst is yet to come. As such, some school districts are already preparing for a couple of lean years. According to Jim Warford, the executive director of the Florida Association of School Administrators, some districts are already cutting discretionary spending.
