New training module from @HEIW_NHS states: "the main purpose is to achieve a better alignment of an individual’s gender identity with the physical body and/or social gender role". Let's be clear that this means medical and/or social transition.

'Gender identity' (described as 'an internal sense of self') is taken as a fixed immutable reality which must be matched by a 'social gender role' (the specific role for girls v boys is undefined) and the physical body (biologically male or female and impossible to change).

The section on children & young people states: "the only way to avoid damaging their well-being is to embrace their identification and how they navigate the gendered world in the moment." This is a very strong claim. Where is the research and evidence to support it?

What are the alternative ways to support a child or young person who is distressed about their gender, and what research shows these methods are damaging to a child's well-being? Is affirming to the child that they are the wrong sex the only way and has it been proved safe?

Health Education and Improvement Wales claims the module "updates on current terminology and language." This is true, it 'updates' scientifically correct terms with the terminology and language of a current ideology promoted by a cohort of political lobby groups.

The resources link to GIRES, Mermaids, Stonewall, Gendered Intelligence, all the usual suspects. @HEIW_NHS could you let us know why you reference these organisations with a shared ideological belief and political goals but with no clinical or medical qualifications?
