    10 Fascinating Facts about British schools


    1.Schools in the UK differ from many countries in Europe in that students start semi-formal education at the age of 5 or younger (with students frequently starting in September of the school year in which they will turn 5).

    2.One way in which the British school system differs considerably from that of other countries is that it is virtually unknown for students to repeat a year. While in other countries, a student who hasn’t got up to the required level in a particular school year will simply be required to do the whole thing again in the company of a new set of classmates a year younger than them, in Britain this is exceptionally rare, and usually only happens in fringe cases at the primary school level (such as in the case of a student born in August who would have been in the year below had they been born in September).

    3.In many countries across the world, most of the ways in which state schools are run is dictated to them by an external body, such as a local or state-level authority.
    This isn’t the case in the UK. 

    4.British schools have increasingly been required to do more than simply teach their students the national curriculum and then throw them out into the world. The school day proper may run from 9am to 3.30pm or thereabouts, but many schools have breakfast clubs from 8am or earlier (to accommodate students with parents who work full-time) and after-school clubs that might run until 4.30 or 5pm. Choirs will practise during lunchtimes and after school; there is after-school sports practice; and there may even be the option of picking up an extra qualification with after-school lessons.
