The UK government finally published its long-delayed guidance for England’s schools on youth transition. The document promises a clear set of principles for teachers and staff as they wrestle with the needs of children who are questioning their gender identity. According to the education secretary, Gillian Keegan, the guidance “puts the best interests of all children first”. But while the guidance has been broadly welcomed by those who believe that it is too easy for young people to “socially transition” at school, there are others who disagree vehemently. They see the government’s approach as informed by an underlying hostility to trans people, and scepticism about whether they even exist. And although the guidance does not include an outright ban on allowing social transition (said to have been under consideration until it was found to be unlawful), it clearly creates new barriers for teenagers who want to talk to teachers about their gender without fear of being outed at home.
