Bit of controversy at our school at the mo - it is usually very strict on uniform - year 11s have a leavers assembly just before half term, prob similar to most schools, as it's the last day that the whole of the year group spend together.
The year 11s then come in for their exams/revision sessions as and when, in their own clothes. I don't see a problem with this but there have been a few complaints - mainly about some kids looking scruffy, but also about girls in 'inappropriate' clothing - very short shorts, crop tops etc.
Just wondered what MN view is. This is the first year the school have done this.
