What is the definition of 'classroom spending?"

Huntsville Item Online - Huntsville, TX: "Following two failed special sessions of the Texas Legislature for education finance reform, Gov. Rick Perry ordered education commissioner Shirley Neeley to restrict how much Texas schools can spend outside of classroom expenses. Under Perry's order, districts will not be allowed to spend any more than 35 percent of their budget on non-classroom expenses, but Huntsville ISD superintendent Richard Montgomery wonders what exactly Perry means by classroom expenses.

'The first thing that I would wonder about is how does he define classroom expenses?' Montgomery said. 'I really don't know what that means at this point. The other thing is, what is the indicator from an educational standpoint that caused him to pick 35 percent as the number?'"
