As the Cass report says, social transitioning is not a neutral act. It can concretise what is simply a passing phase for a child.
The Cass Report
does not say that.
It says:
"Social transition – this may not
be thought of as an intervention or
treatment, because it is not something that happens within health services.
However, it is important to view it as an active intervention because it may have significant effects on the child or young person in terms of their psychological functioning. There are different views on the benefits versus the harms of early social transition."
So, unless I am mistaken you have inserted the bit about "concretising" yourself and are passing it off as Cass's words. Happy, to be corrected if you can find Cass saying that. I have parsed the report and cannot.
...and it does not contain anything at all about schools, other noting that opinions were heard during the course of the review.
One of the problems with the Cass Review is that an awful lot of people cite it without having read it. What they have read are other people's interpretations, particularly from pressure groups from both pro and anti sides of the spectrum, for example Mermaids and Sex Matters. The Internet is awash with these, and some of them contain wilful distortions which then get bandied around as fact.
Ditto 'department for education guidance for schools'. Try googling this and you'll get pages of pressure groups telling you what they thing the DfEs advice should be, but nothing from the DfE.
