Michelle Farley, 40, will have to register as a sex offender as part of a plea agreement reached with Ada County prosecutors Friday.

Farley pleaded guilty to one charge of sexual battery Friday. Prosecutors dismissed seven others. They are recommending Farley serve 10 years of probation with the possibility of up to a year in the Ada County Jail. She will have to undergo a psycho-sexual evaluation.

Farley’s attorney, Chuck Peterson, can argue for a lesser sentence at the upcoming sentencing hearing scheduled for June 19.

Farley was calm and stoic during Friday’s hearing, responding to 4th District Judge Timothy Hansen’s questions with simple “yes” and “no” answers.

Her husband and other family members attended Friday’s hearing but declined comment afterwards. According to court records obtained by the Idaho Statesman, the teen told police he had as many as 15 sexual encounters with Farley between May and Oct. 30. The teen said the sexual activity did not occur at the school but at a park close to Borah High and at Farley’s home. Farley admitted in December she had sexual contact with the boy, according to court testimony.

Neither police nor prosecutors have said how the two met or whether the boy was one of Farley's students.

The maximum penalty for the charge of sexual battery of a minor is life in prison.

Farley, who was hired by the Boise School District in August 1994, was still listed on paid administrative leave Friday, according to Boise School District reports.

District officials said Friday that Farley’s status will be reviewed as early as next week. A teacher can only be taken off paid administrative leave by school board action.

Farley taught psychology at Borah High and earns an annual salary of $55,971.

It will be up to the Idaho State Department of Education Professional Standards Commission to determine whether Farley will lose her teaching certificate, and the commission can’t take action until it reviews Farley’s case. That likely won’t occur until all the legal proceedings are over.

Department of Education spokeswoman Melissa McGrath said Friday in general terms that it is likely any teacher convicted or found guilty of sexual misconduct with a minor will have his or her teaching certificate revoked.
