Separate Changing Areas for Year 5 / 6

[McBainClan1970]

I'm trying to get some ideas what happens at other Primary schools with regards to changing for PE. At my son's school they do not have any changing facilities so they all get changed together in the classroom. My son is in year 6 and there are some well developed girls and boys. With regards to Safeguarding from adults and the opposite sex (children) I would have thought it to be best practise to provide separate changing areas?
Let me know your thoughts and what happens in your children's school.
Thank-you

Our school has 2 classes per year. Both classes do pe on the same afternoon/morning but not at the same time.

Both yr 5 classes get changed at the same time, girls in one classroom, boys in the other. 1 class goes out to people, other class does classroom stuff in their pe kits. Then they swap over. Once both classes have done pe, they all get changed again, boys in one class girls in the other. Yr 6 is the same.
