Most States Have Cut School Funding, and Some Continue Cutting

December 10, 2015

Most states provide less support per student for elementary and secondary schools than before the Great Recession.Most states provide less support per student for elementary and secondary schools — in some cases, much less — than before the Great Recession, our survey of state budget documents over the last three months finds.  Worse, some states arestill cutting eight years after the recession took hold.  Our country's future depends crucially on the quality of its schools, yet rather than raising K-12 funding to support proven reforms such as hiring and retaining excellent teachers, reducing class sizes, and expanding access to high-quality early education, many states have headed in the opposite direction. These cuts weaken schools' capacity to develop the intelligence and creativity of the next generation of workers and entrepreneurs. 

Our survey, the most up-to-date data available on state and local funding for schools, indicates that, after adjusting for inflation:

·         At least 31 states provided less state funding per student in the 2014 school year (that is, the school year ending in 2014) than in the 2008 school year, before the recession took hold.  In at least 15 states, the cuts exceeded 10 percent.

·         In at least 18 states, local government funding per student fell over the same period.  In at least 27 states, local funding rose, but those increases rarely made up for cuts in state support.  Total local funding nationally ― for the states where comparable data exist ― declined between 2008 and 2014, adding to the damage from state funding cuts.
