Inspector General Nicholas Schuler noted the finding in a 75-page report released Wednesday showing other alleged wrongdoing including an elementary school principal spending over $20,000 in school funds for personal shopping and families using false addresses to get children into competitive schools.

The report doesn't identify schools or employees by name. It covers investigations between July 2016 and last June.
In another case a principal used school money to pay for a "teachers' lunch club" with lobster and steaks.
Schuler says two employees resigned and two others were fired after investigations.
School officials say the district is addressing issues raised in the report.
In a statement, the Chicago Teachers Union said, in part: "With all of the resources that our students and their families lack, both inside of the classroom and in their own communities, it's extremely disappointing to witness such selfishness coming from school administrators and Central Office."
