An Arkansas study, which claimed greater ROI for charter vs. public schools, has drawn criticism.

According to The Daily Caller, the study found that on average, for every $1,000 per pupil spent on teaching a particular subject, charter schools produce a 40 percent greater return in terms of student test scores. The National School Board Association (NSBA) questioned these results and said there are too many differences between the two types of schools to make a valid comparison.

"Making an apples to apples comparison of how much funding charter schools receive to provide similar services as traditional public schools is not taking an advocacy position," said Jim Hull, senior policy analyst with NSBA's Center for Public Education. "It can be done with objective statistics."

Hull said making a completely fair comparison of charter and public-school budgets would be 'an arduous undertaking' requiring far more scrutiny of individual items in school budgets, but explained that until such an undertaking is made, the schools simply cannot be compared with one another.
