A teacher from Cornwall has been jailed for a year after admitting indecently assaulting a 15-year-old girl who had a crush on him.
Ashley Theasby, from Church Cottage, Cubert, near Newquay, was also banned from working with children for two years at Truro Crown Court.
The 25-year-old, who had just qualified to teach geography, is also to register as a sex offender for seven years.
The judge told him "your career as a teacher has ended".
The court heard that the girl had a crush on him and Theasby's defence council said he was a foolish young man who had succumbed to temptation.
He ended the affair after the one indecent assault, which he said he regretted.
The judge accepted that the young girl was a willing participant and that Theasby had been of previous good character.
