A former Pleasant Ridge Elementary School first-grade teacher faces a three-year sentence on her guilty plea to sexual battery by an authority figure.
Kara K. Israel, 35, also is now registered as a sex offender.
In June, Israel pleaded guilty in Knox County Criminal Court.
The charge alleged Israel had sexual contact at various times with a boy who was between the age of 13 and 17 from August 2015 to Oct. 27, 2015.
She resigned Feb. 18. She had worked as a teacher in the school system since 2004, beginning as a kindergarten teacher at Brickey-McCloud Elementary School, according to school officials.
She was placed on administrative leave with pay on Oct. 22, 2015. She earned $44,900 annually.
