This behaviour from the teacher is completely unacceptable and potentially very damaging to your child. Gender reassignment is a protected characteristic under UK law, which means deliberate misgendering can constitute discrimination under the Equality Act 2010. When a teacher consistently uses the wrong pronouns despite knowing better, they are putting their personal views above your child's wellbeing and legal rights.
Recognising the difference between mistakes and discrimination
The key factor is whether the misgendering is deliberate rather than an honest mistake. Occasional errors that are quickly corrected with genuine apologies are understandable, but a pattern of persistent misgendering despite correction indicates discriminatory behaviour. This creates a hostile environment that can seriously harm your child's mental health and school experience.
Taking action through the school
Document these incidents carefully, noting dates, times, witnesses, and the specific language used. Raise a formal complaint with the school in writing, as schools have legal obligations to prevent discrimination and create an inclusive environment for all students. The teacher's behaviour could expose both them and the school to legal action, as they have a duty of care to protect all students from discrimination.
When schools fail to respond appropriately
If the school fails to address this appropriately after your formal complaint, you can escalate to the local authority or Department for Education. The school's inaction could constitute a breach of their duty of care and their obligations under equality legislation. This persistent discrimination can have serious consequences for your child's educational experience and mental health.
