The head of human resources for the Prince George’s school system will resign effective Aug. 15, according to school officials.

Synthia J. Shilling, who faces a trial this month on a charge of leaving the scene of a car accident, told school officials earlier this week that she planned to resign. At the time, she did not say when she would leave.

Briant Coleman, a schools spokesman, said Shilling’s resignation comes five days before schools open on Aug. 20. Shilling was hired in Prince George’s in 2006 and named to her current post in 2010.

This month’s court appearance will not be Shilling’s first since being employed by the school system.

Four years ago, she was given probation before judgment and fined more than $400 for second-degree assault on a Maryland state trooper. She also received probation before judgment for driving while impaired at the time of the incident.

The probation before judgment sentence came before Shilling was promoted by School Superintendent William R. Hite Jr. to her current position.

Coleman said Hite would not respond to a request to discuss his decision to promote Shilling or her employment status since her run-ins with the law.

Shilling’s departure comes as the Board of Education is searching for a replacement for Hite, who has taken a job to lead the schools in Philadelphia.

An interim superintendent is expected to be named by Aug. 15.
