Martinez: Study shows which STOs help underprivileged students

Fifteen years ago, the Arizona lawmakers crafted legislation making possible School Tuition Organizations. The goal was to make a private school education more accessible to all Arizona families. It seemed like an ideal situation. Individuals and businesses that donated to these organizations received tax credits that reduced their state tax bill by the amount donated. Deserving kids from poor and working class families would receive scholarships giving them the type of private school education traditionally reserved for the well-to-do.
