DES MOINES, Iowa (AP) — At least 103 cases of teacher misconduct in Iowa were omitted from a national database since 1990. The Des Moines Register’s investigation  revealed errors in Iowa’s information, so state officials have ordered a full audit of the system.

Duane Magee leads the Iowa agency that licenses teachers. He says the state wants to make sure that all of the teachers sanctioned in the state are reported to the national database. State law also limits the amount of information the state Board of Educational Examiners can share about teachers, which could make it hard for school districts to ensure they’re not hiring someone with a criminal record.
