Authorities say 33-year-old Katherine Leigh Preusser was arrested March 23 after a car in which she was a passenger was pulled over in Middletown. Police say two 17-year-old Ridley High School students were also in the car, along with several open cans of beer.
She's facing charges for allegedly providing alcohol to students.
The Delaware County Daily Times reports Superintendent Lee Ann Wentzel says she learned about the incident over spring break and has suspended Preusser while an investigation continues.
A telephone listing for Preusser could not be located and it wasn't immediately clear if she had an attorney.
