Oliver Glass

Oliver Glass, aged 33 at the time of conviction, was a graduate of the University of Oxford. At the time of arrest, he was head of maths at the independent day school, St Joseph’s College, Reading. He left his employment at the school in October 2019. At the time of conviction he was living in Sheffield.

The offence

The maths teacher sent the female pupil explicit texts and Snapchat messages. He engaged in sexual intercourse with her in his car, after a school sports day. He then had sex with the pupil on two further occasions, when she had reached the age of consent. The judge said that the victim survivor had been subjected to “rough sex”, which made the offences “particularly unpleasant”. The offences occurred between June 2019 and August 2019.

Glass admitted three counts of causing a child to engage in sexual activity when he was in a position of trust. He pleaded guilty at a hearing on the 7 October 2020.


Oliver Glass was handed down a prison sentence of 22 months. His details will also be added to the sex offenders register, for 10 years.

School Statement

The school said, “We deeply regret that a former member of staff should have abused his position and betrayed the trust placed in him in such a shocking way, and we applaud his victim for having had the courage to speak out.

"The member of staff was suspended as soon as the matter was brought to our attention and he left our employment in October 2019.

"We take our safeguarding responsibilities extremely seriously, and whilst there can never be room for complacency with regards to safeguarding matters, I firmly believe the measures we have in place here are the most stringent and effective in our school's history - they were independently reviewed last January."

 Police Statement

Investigating officer, Detective Constable Helen Gasson, based at Reading police station, said: “Glass abused his position of trust and took advantage of a vulnerable child.

“He also abused the trust that was placed in him by her parents and the school she attended.

“I would like to thank the victim for her courage and bravery in coming forward to report this to us.

“Thames Valley Police takes reports of this nature very seriously and will investigate thoroughly.”

Comment by the NSPCC

A NSPCC spokeswoman said: “As a teacher, Glass’ role was to safeguard his pupils, instead he abused his position of trust to sexually exploit his victim.

“Child sexual grooming and abuse can have a devastating impact on people’s lives and it is important this teenage girl, who has bravely spoken out and helped bring Glass to justice, now receives all the support she needs. 

“The NSPCC has been calling on the Government to extend position of trust laws to cover all adults working with young people, including sports coaches and youth workers, so it is illegal for them to groom and exploit 16 and 17-year-olds.”
