MORE: Hamilton teacher pleads guilty to sex crime with student
The crime involved a female student and an encounter that occurred off school property last fall, according to Hamilton police.
Dattilo, of Monroe, turned herself in to police in January after her indictment. She has been free on $5,000 bond.
Police said parents reported a possible inappropriate relationship between Dattilo and the student to a school staff member, and police began an investigation.
Dattilo was placed on unpaid leave by the district when the investigation began.
Hamilton Superintendent Larry Knapp confirmed to the Journal-News on Tuesday that Dattilo is no longer employed with the district, and a letter received from the state said her teaching license has been revoked.
