A teaching assistant who performed sex acts on a 15-year-old pupil has been jailed for 32 months.
Jill Meldrum-Jones, 37, committed several offences against the boy during a flight and on a school trip.
The offences came to light after rumours circulated relating to her, Coventry Crown Court heard.
Meldrum-Jones, of Kineton, admitted a total of seven charges of sexual activity with a child and inciting sexual activity.
Prosecuting, Stefan Kolodynski said Meldrum-Jones sent text messages to the boy making clear reference to what had happened and containing “conversation geared towards arranging further sexual congress”.
A victim impact statement submitted to the court heard the boy, who cannot be identified, has since felt very nervous and embarrassed.
Jailing her, Judge Philip Gregory said it almost beggared belief that somebody from her background, happily married with two children and intelligent, should lose control of her senses and judgment.
He accepted the offending was “grotesquely out of character” for her.
In mitigation, Simon Hunka suggested her behaviour was “unbelievable in its riskiness” and may have been linked to depression or her mental state.
