What is the percentage of national education budget spent on teacher salaries and benefits?

There's no single answer to the percentage of the national education budget spent on teacher salaries and benefits in the United States. The percentage varies significantly from state to state and even within school districts in the same state. Factors influencing this include:

* State funding formulas: States allocate funds differently, prioritizing various aspects of education.

* Collective bargaining agreements: Teacher unions negotiate salaries and benefits, creating variations across districts.

* Cost of living: Salaries and benefits are adjusted based on local economic conditions.

* Student population size and demographics: Districts with different student populations will have different budgetary needs.

To find this information, you would need to specify a state or school district and consult their budget documents. Even then, the exact breakdown between salary and benefits may not be clearly delineated. The U.S. Department of Education provides overall education spending data, but not this specific breakdown at the national level.
