I would be extremely concerned about the Stonewall material in schools - I know, because my child's secondary school uses it and I requested a copy of the pack, which:
- includes a quiz for year 8s about young people who identify as transgender. What percentage of young people (multiple choice) have attempted suicide. The fake figure it actually gives was debunked by the NHS and Stonewall has already been asked by many groups not to use such dangerous, misleading and false information
*It describes the term homosexual as a 'medical' definition
- It describes transsexual as an 'old fashioned' term
There are other issues, especially with its glossary of terms that includes 'cis' and that old chestnut 'assigned at birth' 
Transgender teacher Debbie Hayton did a detailed analysis for TES of school guidance from key groups including Transgender Trend, Stonewall and Gendered Intelligence and recommends schools use Transgender Trend's resources.
Noble Jan the Mermaids trainer goes into schools and tells teachers that children should be able to use any toilet if they self ID as that sex and that this is covered by the EA. This was recorded and transcribed (see below). This is incorrect (see Transgender Trend links below Jan's words.
Many parents and teachers have also contacted the DfE and EHRC for clarification regarding 'gender reassignment' in the EA and children.
Jan:
*So toilets, changing rooms, sports, residential. The Equality act is unambiguous its crystal clear. Unisex and gender neutral facilities are absolutely fine, but that’s not a disabled toilet with a sticker on.
But you can’t prevent anyone from using the facilities of the gender with which they identify and are living as. If someone complains, you provide an alternative to the person complaining. THAT IS THE LAW.
If you get a what if? which you will, just replace one protected characteristic with another and ask yourself the question again. So what would happen if you said ‘you can’t use those toilets because you’re Jewish?
Usually if you’ve got a ‘what if?’ just do that and it will quite often just give you the answer and then you can go ‘OK, I can deal with this. It’ll be fine. So that’s for primary schools..*
Transgender Trend has some good advice here on the subject of the EA: www.transgendertrend.com/uk-transgender-rights-legislation/
They say:
After questioning by the campaign group Fair Play for Women, the EHRC was forced to clarify that a person without a Gender Recognition Certificate (GRC) is treated for sex discrimination purposes as their legal sex. No child under the age of eighteen has a GRC so a male child is still legally male even if he identifies as a girl.
