Matthew DeFour:

The Department of Public Instruction has declined to revoke the license of a teacher accused of immoral conduct 88 times, or in only one out of every five cases, since State Superintendent Tony Evers took office a decade ago.

In a greater number of cases, 150 out of the 432 investigations opened since July 2009, the department revoked or denied teacher licenses after investigating allegations of immoral conduct.

Another 121 investigations are on hold because the teacher’s license expired while the investigation was ongoing. DPI spokesman Tom McCarthy emphasized none of the teachers in those cases are still in the classroom. The final 73 cases remain open.

The Republican Party of Wisconsin has turned license revocation into an issue in the governor’s race between Evers and Gov. Scott Walker, spending roughly $1 million on TV ads over a two-week span featuring three of those 88 cases in which the department didn’t revoke a license.
