Accountability

The Parental Choice Program is one of the most regulated in the country.

By law, each participating school must be accredited, provide background checks on teachers, proper record retention, appropriate curriculum and a board of governance. They must
also meet all Federal safety and anti-discrimination guidelines.

Changes to state law over the years have made it much more difficult for new schools to enter the program. In addition, schools must provide comprehensive financial audits that are reviewed annually by the Department of Public Instruction. DPI has the authority to deny, withhold funding, or remove schools entirely from the program.

Furthermore, all schools receiving public funding must publish a
report card precisely detailing the productivity of those specific students. All schools, regardless
of sector, are judged on the exact same merits.
