Deputies took Dattilo into custody for transport to the Cincinnati program. She has been free on $5,000 bond that was posted after she turned herself into authorities in January.
Dattilo is no longer employed with the district, and a letter received from the state said her teaching license has been revoked, according to Hamilton Schools Superintendent Larry Knapp.

The crime involved a female student and an encounter that occurred off school property last fall, according to Hamilton police.
Dattilo made no statement during the short sentencing hearing. The victim also did not speak.
The River City program takes about four-to-six months to complete, according to Butler County Assistant Prosecutor Kelly Heile.
Hal Arenstein, Hilary Dattilo’s attorney, said the sentencing was continued two weeks ago while Dattilo was assisted for a correctional center program.
