I was more asking if in general, would art classes be co-ed or separated by gender specifically where nude models were concerned. The comments I received so far however, reminded me that nude models may not even be used for 'high school' level art classes (maybe 6-7 years in the case of Hogwarts). I do thank everybody who has responded so far, your feedback has been helpful and I'm sure I can dredge up my own experiences taking art in school before I took it in college.

I welcome more comments if anybody has any but for now I have enough info to get a lesson post up for all the art students at Hogwarts.
