Despite cuts to state school aid in 2010, and slower growth of school revenue limits in 2010 and 2011, Wisconsin per student spending increased 2.6% in 2010 and 3.6% in 2011. Wisconsin school spending averaged $11,774 per student in 2011, 15th highest nationally and 11.5% above the national average ($10,560).
What is not yet known (since federal data have a two year lag) is how Wisconsin will stack up with other states in light of state budget actions in 2011-13. However, researchers from the Wisconsin Taxpayers Alliance (WISTAX) estimate that the 5.5% cut in 2012 Wisconsin school revenue limits will trim spending to $11,126 per student, potentially shrinking the gap between school spending here and nationally. WISTAX is a nonpartisan, nonprofit research organization dedicated to policy research and citizen education.
The new federal figures for 2011 show that, unlike Wisconsin, many states saw declining combined aid (state and federal) to schools during 2009-11; 11 states in 2009, 17 in 2010, and 22 in 2011. By contrast, state-federal support in Wisconsin rose 3.3% in 2009, 0.4% in 2010, and 2.7% in 2011.
The difference in aid trends between Wisconsin and the nation was reflected in per pupil expenditures. U.S. school spending grew 2.3% in 2009 and 1.1% in 2010, before falling 0.5% in 2011. In Wisconsin, however, per student spending during those years rose 3.7%, 2.6%, and 3.6%, respectively.
Many states trimmed school spending during 2009-11. Two states made cuts in all three years, and another seven cut spending in both 2010 and 2011. As national figures have already suggested, retrenchment did not occur in Wisconsin until 2012.
