Melissa Sutterfield, 42, pleaded guilty to the charge.
She admitted to sending a sexually explicit photograph to a then 17-year old student.
As part of a plea deal, Sutterfield was sentenced to five years probation and given a $2,000 fine.
Officials say Sutterfield is not allowed to have any contact with anyone under the age of 18.
