I had the pleasant task of turning a court brief, written by John Eastman, a constitutional scholar, into a policy paper. While copy editing my way through it, I received an unexpected history lesson about how state legislatures, throughout the years, have approached the volatile issue of public education funding. Given that an increasing number of "adequacy and equity" lawsuits are being filed by unions in an attempt to get school districts to receive more tax dollars by judicial fiat, I am confident you will find Dr. Eastman's work a valuable read.
More hard-hitting arguments from OCPAthink: Bruce Shortt's editorial. Isn't he a marvy home ed advocate: " ... here is my modest proposal: Oklahoma's homeschooling parents should regulate Oklahoma's public school bureaucrats until Oklahoma's public school students academically outperform homeschooled children."
