RIDER COMMENT: One core tenet of public education is this: ”More spending on education provides better results.” It’s intuitive, axiomatic — and dead wrong.
Here’s the summation of a recent study (one of several) verifying this lack of correlation. Indeed, closer inspection often reveals an INVERSE correlation. A second, more detailed study is included below as well.
Obviously correlation does not prove causation, but a LACK of correlation makes any causation claims highly suspect. Most studies that DO conclude there is some causation are produced by and for the public education employees — and often even funded by such groups (primarily labor unions).
