After 12 years, James Sullivan will step down as Chicago Public Schools Inspector General when his term ends June 30. Sullivan named his three children, one of which is headed to college in August, as the reasons behind his resignation.

He earned $133,000 a year in the public sector, and he will join Sikich LLP to work on fraud investigations. Previous to his role as inspector general, Sullivan worked as deputy inspector general for the City of Chicago and worked as a prosecutor in the Illinois Appellate Court.

With a $2.5 million budget and 32 employers, the Office of the Inspector General investigates fraud by employees and businesses under contract with the Chicago School Board.

Over the past 12 years, Sullivan investigated the spending of taxpayer money by former School Board President Michael Scott. He also investigated clout admissions at several CPS selective enrollment schools, as well as inflated grades, graduation rates and attendance rates.

The inspector general has no power to enforce changes within the education system and can only make recommendations based on investigations. With his term ending, Sullivan is calling for more funding for the office of the inspector general, which has one investigator for every 2,356 employees.
