Arizona charter school officials say they don't want the state to impose more regulations on how the mostly privately operated schools buy goods and services with taxpayer dollars, and the state board says that's OK with it.

The State Board for Charter Schools held a study session with charter school officials Wednesday in response to a newspaper's investigation that found that officials of some charters did business with their own schools.

School officials told the board that more regulations would impose burdens on the schools and that policies in place are reasonable.

The Arizona Republic reported that no board members suggested policy changes and that Executive Director DeAnna Rowe said the board will continue to operate as it has.

The Republic's report last year found that school board members or administrators ran companies that sold goods and services to their schools. In many instances, those schools hold exemptions from state law that requirews competitive bidding.

At least 17 no-bid contracts or other arrangements between schools and people affiliated with them involved more than $70 million in purchases over five years for 40 school sites, the Republic said.
