A 15-year-old boy has admitted stabbing a teacher in a school corridor.
Maths teacher Jamie Sansom was taken to hospital after the attack on 10 July at Tewkesbury Academy.
The teenager, who cannot be identified because of his age, on Monday admitted one charge of attempting to cause grievous bodily harm with intent.
It came at the start of a two-day trial at Bristol Magistrates’ Court.
The boy had previously pleaded guilty to a charge of possessing a bladed article following the attack.
Mr Sansom, who has taught maths at the school since 2017, was discharged from hospital on the same day he was attacked and said he was “recovering well”.
The defendant was remanded in custody until a sentencing hearing at Cheltenham Youth Court on 28 September.
District Judge Lynne Matthews told him: “We’ll need to know more about you and the court will need to hear proposals from the youth offending team.
“I don’t know what your sentence will be – I’m not going to guess.”
