I have had a response to different questions, I hadn't picked up on those suggested here. This is a brief summary.
My initial e-mail said:
I have failed to find any statements or policies regarding transgender issues on the NSPCC website. Please could you explain why the NSPCC does not consider there to be child protection concerns with policies that effectively abolish single sex spaces.
NSPCC said:
Firstly, the NSPCC doesn’t consider there to be specific child protection concerns in relation to trans-inclusive policies. Any space and activity involving children should have strong safeguarding policies in place, with a proper risk assessment to minimise the risks to all children involved. And every adult working with children should undergo rigorous safety checks and vetting procedures to ensure that young people are safe in their care.
Additionally, trans young people are at particular risk of physical, sexual and emotional abuse from peers. This can heighten the risk of abuse by adults as children turn online for support and access to networks of those sharing similar views and feelings. There should be high-quality, statutory relationships and sex education, alongside strong school safeguarding policies, to ensure that all children are kept safe in schools.
I went on to ask:
When you say "any space and activity involving children should have strong safeguarding policies in place, with a proper risk assessment to minimise the risks to all children involved" would that include recommending separate male and female overnight accommodation and washing facilities for e.g. school trips, Cubs, Scouts? Or would NSPCC advice be that mixed sex accommodation is fine for all ages?
About a week later I received:
Thank you for contacting us and sorry for the delay in replying, we’re a small team experiencing a rather busy period at the moment.
Organisations need to put appropriate safeguarding measures in place in any activity involving children, whether any of those involved identify as trans or not, and comply with their legal obligations under the Equality Act. Organisations must handle any reasonable adjustments being made for trans-identifying children with sensitivity towards all involved, while ensuring they are complying with their legal obligations. Being trans is not in itself a child protection issue, and being trans does not make an individual more of a safeguarding risk than any other person. Under the Equality Act it is every trans person’s right to be able to use the toilet they want to and when considering measures such as unisex toilets we would advocate careful thought be given to ensuring mixed groups are safeguarded.
So I went off to educate myself on the Equalities Act and it didn't take long. When I have more time and better IT I'll send them back links to the very clear government guidance that says transpeople may be refused access to single sex services where that decision is justifiable in the interests of other service users. I don't understand how anyone who had spent more than 30 minutes looking at the guidance could come to a different conclusion.
