With Arizona public schools struggling to raise students’ standardized test scores, the Legislature in 1994 began a grand experiment: charter schools.
They were exempted from state procurement or conflict-of-interest laws and the oversight of elected boards. With less regulation, charters could succeed where traditional public schools had failed, proponents argued.
Today, about 16 percent of Arizona students attend a charter school. And one of the state’s big chains, Basis, operates some of the best public schools in the country.
