You seem to have misunderstood what was going on @Newbutoldfather.
This is from the article that Kevin Lister wrote for the Daily Mail.
My ordeal began in September 2021, when I received an email from one of my A-level pupils, Lizzie*, informing me that she wanted to be known as 'Liam', and addressed with male pronouns.
The request came out of the blue. There had been no suggestion that she felt uncomfortable as a girl.
Concerned about Lizzie's wellbeing, I raised a safeguarding concern with the school — Swindon New College — and asked if her parents had been notified or asked for their consent to their daughter changing gender at school. I also raised the possibility that she might be self-medicating with testosterone.
The reason for this is that I had read reports of young women recklessly purchasing this hormone online — which aids the physical transition from female to male — if they are unable to obtain it on prescription.
A few weeks later, the college's safeguarding team told me they were not going to contact Lizzie's parents. They didn't justify this decision, but I strongly believe the college was taking the advice given by trans activist groups not to inform parents of a student's gender change without the child's permission.

He was concerned about the wellbeing of the student. He thought her parents should be informed and her transgender identity should be discussed with them. The school decided her parents didn't need to know and shouldn't be informed. The school acted recklessly.
