it's only possible to guess the aims of some changes. Kids have always been graded for educational needs one way or another. These days it looks like the stats or what ever they are called are used. The grading sets levels and pace etc but it still wont be even so teaching assistants appear to try and help even it up. More use of PC's etc. Maybe a broader range of curriculums - yet more teachers needed.Do you think this might have a tiny little weeny implication:
Class sizes in England’s state secondary schools have ballooned to their largest size for nearly 20 years
LOL A class size of 22 sound rather small to me at any stage of most of my schooling.
