The 27-year-old then had sex with him in June, and resigned from her position that same month, the indictment from Woodford County states, reports the Daily Mail.
Jarvis is accused of continuing the sexual relationship with the boy even after she got a job as a para-educator at Veterans Park Elementary in Lexington in August 2016.
She was arrested on Friday and resigned from her position the same day.
The student's identity and age have not been disclosed.
Lisa Deffendall, a spokesperson for Fayette County Schools, confirmed Jarvis is no longer a teacher at the elementary school and said they are 'aware of the matter'.
On her 25th birthday, husband Andrew Jarvis paid tribute to his wife, writing: 'Happy 25th birthday to my sweetest Lindsey!
'So thankful for your wonderful heart, which teaches me so much about compassion and kindness.
'So thankful for your wisdom and discernment that help guide us through life....Love you with all my heart, and so thankful to have you as my best friend.'
