A school counselor has been fired after admitting to having a sexual relationship with a student who she would text and FaceTime in the day and then meet in her private office after hours.

Kenleigh Prendergast, 25, had only been at Spartanburg Day School in South Carolina for five months when she is said to have started the inappropriate relationship with a pupil 'aged 16 or 17' in January this year.

The counselor said the attachment ended several days before she was reported to police on March 25.

She was interviewed on March 30 and confessed to communicating with the student via text, cellphone calls or FaceTime during and after school hours.

This led to the pair meeting outside of school in her house, which doubled up as a private counseling practice, she said.

Prendergast was taken to the Spartanburg County Sheriff's Office Detention facility and charged with sexual battery with a student aged 16 or 17 with no aggravated force or coercion.

The school, which charges up to $19,000 a year in fees, said it fired Prendergast as soon as they were informed of the allegations by police.

It said in a statement: 'Spartanburg Day School was contacted on March 31 by the Spartanburg County Sheriff's Office and informed that an employee, Kenleigh Prendergast, was charged with sexual battery with a student.

'Ms. Prendergast was hired in August of 2017 as school counselor.

'Effective immediately, Ms. Prendergast's employment with the school has been terminated.

'SDS puts the safety and wellbeing of our students above all things, and will cooperate fully with the Sheriff's Office throughout this process.'
