Because both kindy and pre-primary aren't compulsory, I think the uniforms aren't compulsory either. Having said that, at my ds's kindy every kid wears the uniform and in the pre-primary class there's only one who doesn't. Was it all year groups you saw or just the littlies?
I would say they were having a casual day Most school have a uniform, I don't think it's always compulsory but more parents get them. Jaidans kinda in Hobart wasn't compulsory but there were only 2 kids in his class of 35 that weren't in uniform.
As for duty teachers, my boys go to a really great private school, and there is only 2 teachers on duty at break times. I don't think it means anything about the school.
