No I think it’s more the discipline side (and sort of parenting on a mass scale )of thing ,so that they can identify you (in the school grounds or near the school grounds ),because the comprehensive schools have a large amount of pupils compared to the primary school ,that divide them into houses ,the classes are exactly the same as your classes and just so we understand !we all don’t just go into twee! little houses ! you can be visually identified by a piece of thick ribbon (different colour each house )that’s sewed onto a top pocket.
So, just to make sure I understand. There are typical classes with your peers (do I understand well that they are divided by subject, so Maths, English, Art etc. - are there classes like Maths Class A or something?) that you have every day that can change depending on the timetable (do classes and students in the classes changed throughout the academic year?) but throughout the whole education in that specific school, you are counted as part of a house. Your classes can be with students of different houses and you can see the difference between houses by wearing some visual sign like a coloured ribbon.
But then... what's really the point of houses?
