when looking at the NMC's submission for the GRA fully supportive of self-id, I came across this paragraph:
While the numbers in this category is low and should be interpreted with caution, our data suggests that trans nurses, midwives and nursing associates are more likely to be referred to us to assess their fitness to practice. The next stage of our work will involve us digging deeper to understand why these differences exist, which will inform what action we then take.
so I read the report looking at discrimination etc and they mention gender and gender identity but not sex (although sometimes they seem to use gender when they mean sex). I haven't managed to read the whole thing yet but it is very confused.
36.1 We have looked at more protected characteristics (the seven
characteristics for which we have data: age, disability, ethnicity,
gender, gender identity, religion or belief, sexual orientation).
