There’s a common perception in this country that public schools are underfunded, and that if they could only spend as much as private schools do, they’d be in clover. When it is pointed out that the average private school tuition is around half of total public school spending per pupil, defenders of the status quo counter that tuition only covers a fraction of total costs.


So wouldn’t it be interesting to know how much private schools actually spend, in total, per pupil? Well now we do, at least for the state of Arizona.


In a study released yesterday by the Goldwater Institute, I analyze the results of their most recent private school survey. Among the other fascinating findings is that public schools spend one‐​and‐​a‐​half times as much per pupil as do private schools. Or, looked at the other way, private schools spend a third less than public schools.


Some other fascinating tidbits:


Teachers make up 72 percent of on‐​site staff in Arizona’s independent education sector, but less than half of on‐​site staff in the public sector. In order to match the independent sector’s emphasis on teachers over non‐​teaching staff, Arizona public schools would have to hire roughly 25,000 more teachers and dismiss 21,210 non‐​teaching employees.


When teachers’ 9‐​month salaries are annualized to make them comparable to the 12‐​month salaries of most other fields, Arizona independent school teachers earned the equivalent of $36,456 in 2004 — about $2,000 less than reporters and correspondents. The 12‐​month‐​equivalent salary of the state’s public school teachers was around $60,000, which is more than nuclear technicians, epidemiologists, detectives, and broadcast news analysts. It’s also about 50 percent more than reporters or private school teachers earn.


I wonder what effect these numbers will have on the flood of education stories about how desperately underpaid public school teachers are… given that those teachers are earning the equivalent of 50 percent more than the journalists who cover them.


There are many other gems in the full report, including a comparison of the condition of physical facilities between public and private sector schools. Public school lobbyists claim they need loads more money to repair and maintain their buildings, so it’d be interesting to know how private schools cope with this issue on a fraction of the public sector’s budget, hmm?
