KIDS will be thwarted from identifying as the opposite gender in all-but exceptional cases.
Long-awaited trans guidance for schools has been “toughened” to make clear should only pupils “socially transition” in rare instances.
It means there will be a “presumption against” allowing children to swap their pronouns, names and uniforms in class.
But parents will have to agree for their kids to behave as another gender – and even then teachers should be “cautious”.
Changing rooms and toilets will still be based on biological sex rather than someone’s identified gender.
It is understood Education Secretary Gillian Keegan and Equalities Minister Kemi Badenoch have agreed on “tough” guidance due to be released before Christmas.
The pair clashed behind the scenes with figures suggesting Ms Badenoch was pushing a harder line.
It led to a last-minute delay last summer when Rishi Sunak had initially promised the non-statutory guidance.
A government source said: “It’s been toughened recently. Effectively it means there is a presumption against social transitioning.
“It will also say parents should be informed – it’s wrong that such decisions appear to have been taken without parents being involved.”
A Government spokesperson added: “Given the complexity of the issue, we’re taking the time to make sure the guidance we provide is clear. That work is ongoing.
“Any degree of social transition could have significant consequences for a child, so it’s vital the right safeguards are in place.
“The Government has been consistently clear about the importance of biological sex, and the guidance will reflect that.”
