Since 2009, Oklahoma has cut more of its state education funding than any other state in the country, cutting more than $192m since 2009 according to a report released by the Oklahoma Policy Institute.

The cuts came after the state lost more than a quarter of its operating budget because of a series of cuts to the state’s oil and natural gas production tax and personal income taxes initiated in the mid-2000s. While neighboring Texas has an effective taxation rate of 8% on oil and natural gas, Oklahoma’s tax rate sits at a mere 3.2%.

If it were not for the tax cuts on natural gas and oil as well as personal income taxes, the Oklahoma Policy Institute estimates that the state would have an additional $356m to spend on K-12 (primary and high school) education as well as an additional $238m to spend on higher education.
