State lawmakers will attempt to tackle a range of issues in legislative sessions getting under way this month, from making common academic standards a reality and funding schools based on performance, to allowing armed teachers and staff members on school grounds. Their task may be complicated by the still small and spotty economic recovery in many places, and by federal education funding uncertainties posed by the continued wrangling in Washington over the nation's fiscal future. One state exploring the issue, if in general and uncertain terms, is Michigan, where Governor Rick Snyder, a Republican, is considering proposing an overhaul of K-12 schooling that would feature more performance-funding measures.
