“Having a dedicated trans officer doesn’t mean that the fight is over though, it doesn’t mean that trans people now miraculously have equal rights, access to education or adequate support.”
The NUS estimate that there are 28,000 trans students in the UK, while 2014 research found that one third of this group have experienced bullying or harassment on campus.
