Children as young as four are receiving lessons from transgender campaigners (posed by model)

Children as young as four are receiving lessons from transgender campaigners – including a man who revealed to primary school classes that he is a ‘trans man’ and was ‘assigned female’ at birth.

Thousands of pupils have had the controversial classes, in which they are encouraged to explore their ‘gender identities’ and are questioned on what being a transsexual means, The Mail on Sunday can reveal.

Up to 20 primary schools a year pay for the classes, given by campaigners’ organisation Gendered Intelligence. Parents’ groups have reacted with concern that pupils may be ‘frightened’ by the workshops, while experts warned the lessons may confuse young children.

Gendered Intelligence has confirmed it teaches pupils of all ages in primary schools, from reception class – where children are aged four and five – up to Year Six, where pupils are aged ten and 11. The workshops cost an undisclosed sum and have been available since 2008.

The Mail on Sunday has seen footage of Gendered Intelligence conducting workshops with primary classes, in a video available for teachers to hire at the cost of £20.

In one class, Year Six boys at Hotspur Primary in Newcastle are asked to describe the ‘girlish’ things they like to do, while the girls say what ‘boyish’ pursuits they enjoy.

Gendered Intelligence’s founder Jay Stewart, who is giving the class, asks the pupils if they think ‘life will be hard at school if you’re a boy at school who likes doing “girlish things”?’

Mr Stewart then asks the class what they think the word ‘transgender’ means and he follows this by revealing he is a ‘trans man’. He says: ‘When I was assigned at birth, I was assigned female when I was born. So I am transgendered. So have you got any questions for me?’

One girl asks if his ‘friends went off’ Mr Stewart after he made the change. He replies: ‘Most of my friends stayed my friends, which is why they’re such good friends. But I’ve also got lots of friends who are also transgendered and actually there’s a whole community of transsexual and transgendered people.’

At the second school featured in the film, Westerhope Primary, also in Newcastle, Mr Stewart again tells the pupils that he is transgender – despite teachers asking him beforehand not to do so.

Transgender woman Tara Hudson who was forced to serve her jail sentence in an all-male prison was this week moved to a women's jail following a national outcry

Head teacher Jo Warner says that in a conversation with Mr Stewart and the class’s teacher, Katie Salkeld, she said: ‘We want you to look at gender issues, but at the minute we don’t feel absolutely comfortable with you actually saying, “I’m transgender”.’

Yet after the lesson, both Ms Warner and Ms Salkeld said they changed their view and believed Mr Stewart telling the children about his transgender status was right.

Gendered Intelligence describes itself as a not-for-profit ‘community interest company’.

Child psychotherapist Dilys Daws warned: ‘What can get confused is that children who just happen to be unhappy at the moment actually fixing on this being about their gender, when it might be to do with the relationship with a parent.’

Margaret Morrissey, of pressure group Parents Outloud, said four and five-year-olds were ‘far, far too young’ to receive the lessons. She added: ‘We’re in danger of frightening children and making them feel they ought to feel like this.’

Mr Stewart said: ‘It’s so important to be teaching children in schools that they can be anything that they want regardless of the gender that they have been given at birth.
