A Florida high school principal was demoted after he had his math teachers do his son’s middle school algebra assignments.

The Palm Beach Post reports former Lake Worth High School principal George Lockhart asked three teachers to do his son’s online math assignments two years ago. He originally denied the allegation to district investigators, then said he requested help to better tutor his son. One teacher told investigators he did the homework out of respect for Lockhart.

Lockhart also didn’t report some student suspensions to the district and violated other policies. He received a $21,000 pay cut and was reassigned.

Palm Beach Superintendent Robert Avossa said he didn’t fire Lockhart because his “bad decisions” didn’t outweigh the good he’s done.

Lockhart’s attorney, Fred Schwartz, said Avossa was “very fair.”
