We have a local school that used to be private so quite small classes. Mixed ability apparently worked well, as you might expect. It became an academy and has increased the intake over the past couple of years. The classs are now larger and as far as I know mixed ability still (or they were when it came to apply for my DSs). I was not confident that they could keep the same standards with a much higher number of pupils in a mixed ability class. I know that they were advertising for various SEN Staff soon after increasing their numbers, so maybe it because apparent to them that larger classes meant that teachers were less able to focus on pupils’ with additional needs than they had been previously.
I am a cynic, having worked in a secondary school for the past 8 years. There are a lot of changes put in place because of lack of funding, or because it makes things easier for the running of the school but not necessarily better if you see what I mean.
As an example my school used to have an hour and 5 min lunch break. Everyone was on lunch at the same time which meant plenty of Staff available to do lunch duties ie monitor behaviour on yards and Corridors. Better sense of staff morale as colleagues would eat together in the Staff room. Time available for pupils to print out homework, attend a club etc.
They then switched to a system of 2 different 40 min breaks. It’s chaotic and frenzied and doesn’t lead to a calm atmosphere for pupils going into afternoon classes. There is not enough time to sort out pastoral issues properly and often heads of year end up on a different lunch break to children who are need an issue sorting. Not enough time to run any lunchtime clubs. No staff in the Staff rooms which has led to a decline in the sense of cameraderie. Staff lunch duty rota is a nightmare with Staff forever having to ask for a swap with someone on the opposite lunch break. Minimal visible staff around to prevent behavioural issues building up. I’ve had to break up physical fights with no other adult visible or within shouting distance. It doesn’t feel safe to me now.
Yet, both Staff and pupils have voted to keep the system because it means that school finishes earlier. Staff who have kids in local schools can rush off at 3.10 in time to pick them up, unlike before. But it means that that they are often not available after school if you want to set up a meeting with them, and they’re not available to see a pupil who may be struggling with something. It is also said that there are FEWER behavioural issues because of the shorter lunches with fewer pupils on each. My opinion is that no, there are actually MORE, they are just not being seen in the first place by a lot of staff, or dealt with properly due to lack of time so it must FEEL to staff that they are dealing with fewer pastoral issues.
The real reason lunch was switched to a 2 lunch break system was because they built on 2 of the yards and there is now nowhere for pupils to physically go at lunchtime. Complete lack of forethought during the planning process. But because pupils like to get off Home earlier (who’d Have thought it?!) then I am told that “people like this system and have voted to keep it”
Whether it is BETTER for all is a whole other matter.
This is what I suspect is the case with schools choosing to switch to mixed ability classes. They will tell you one or two advantages (while ignoring the major disadvantages), but I suspect the real reason is due to funding as a couple of others have mentioned. Fewer classes will be needed, so fewer teachers. They are getting rid of TAs left right and centre. I suspect that schools are hoping that mixed ability classes will improve the behaviour of disaffected kids too. In my experience that won’t happen in a lot of schools. In my school there are disaffected pupils in sets 2 and 3, not just bottom sets. Brighter pupils in sets 2, for example, often complain that progres of the class is impeded by a couple of kids being naughty then a few others give up and join in.
The other reason they may be doing it is because of the progrsss 8 thing. In my school, low ability pupils are not making required progress. It would surprise me if they decided to change to a mixed ability system to try to raise the aspirations of disaffected kids using the high-achieving hard-working kids as examoles. What should be happening is that bottom set disaffected kids should be given outstanding teachers to inspire them.
Mixed ability classes will not work unless you have extremely good behaviour already across the school and fantastic teachers. I suspect in schools where it seems to be working, behaviour was already good.
