A married teacher who had outdoor sex with her 15-year-old pupil was today jailed for six years and two months as a judge slammed her for taking advantage of a child in her car in a ‘gross breach of trust’.

Mother-of-three Kandice Barber, 35, took the underage boy to a field, kissed him on the neck next to a bale of hay, and whispered, ‘What do you want to do now?’ before having full intercourse with him.

Barber’s lawyer had claimed that at just 5ft tall, the Princes Risborough School supply teacher was too short to have had sex with the pupil, who cannot be named for legal reasons, standing up.

The defendant also lied that her packed calendar meant she was ‘too busy’ to have slept with the pupil, who today said the ordeal had impacted his GCSE results.

Jailing her at Aylesbury Crown Court today, Recorder Bal Dhaliwal said: ‘You [Barber] acted in gross breach of trust. You took advantage of a child in your care and groomed him for your own sexual gratification.’

Barber, of Wendover, Buckinghamshire, had bombarded him with messages including one where she asked him ‘do you like boobs or bum?’, and sent him a photo of herself on a bed surrounded by sex toys.

But she was found out after a topless picture she had sent her victim was circulated around so much it ended up being passed to the headteacher of their school.

Prosecutor David Povall summarised a statement from the victim, who said he faced stress and anxiety as a result of the incidents and going through two trials.

He continued: ‘He was at school and it was through his presence at school that he came into contact with this defendant, who was working there in a position of trust.

‘He feels that his GCSE results were not as good as they should have been, in part as a result of the impact of these incidents on him.

‘As a result of his poorer-than-expected GCSE results he had to leave the good school he was attending and go to a sixth-form college where none of his friends were.

‘In summary, he says that the defendant … who was supposed to help students make the right decisions instead helped him to make all the wrong decisions.’

This was Barber’s second trial, after she was convicted in September of sending the boy topless pictures of herself on Snapchat between September and October 2018 but acquitted of causing or inciting a child to engage in sexual activity while in a position of trust.

The supply teacher was found guilty of one count of causing or inciting a child under 16 to engage in sexual activity. She was found not guilty of two further counts of the same charge.

Barber had shown no emotion when the verdicts were announced following 10 hours and 39 minutes of jury deliberation, staring blankly across the courtroom.

Her delivery worker husband, Daniel, had watched proceedings remotely in a side room, fumed after the guilty verdict: ‘It’s a joke.’ When Barber emerged at the court entrance after her trial he gripped her hand the moment he saw her.  He is standing by her.
