While research is increasing into binary trans identities in educational settings, young people identifying as non-binary have been little studied. We explore the school experiences of eight non-binary teenagers aged 13-18. Our findings suggest that both the implicit and explicit curriculum are strongly binary, making it hard for non-binary young people to come out at school. Respondents had needed to educate themselves about gender identity and specifically about the possibility of non-binary identities, with little, if any, support from their schools. As non-binary identities were invisible at school, some did not feel safe there, and they came under pressure from both transphobic bullying and binary expectations of behaviour and self-presentation. Consequently, some respondents feared accessing any available provision for non-binary people, in case it outed them. Institutions should work harder to educate staff about non-binary identities, and non-binary young people should be involved in designing inclusive initiatives.
