Yes- we have a eys nurture class, quite a range of sen as well as 'just' social problems- all children who struggle in a large, free flow classroom, often poor social, communication and play skills . Love it, children make huge progress. I have 11 but 3 lsas which makes it manageable, also provide some drop in support for other classes.
I have loved all the nurture and EBD work I have done though. Small groups so you actually get to focus on each child's individual needs and you can actually drill down to what each child needs and feel like you are making a difference to the rest of their life. So rewarding.
I'm surprised at schools these days needing a Nurture Group at EYFS level as the key worker and free flow format provides a similar level of individual experience for each child.
I work in an EBD secondary school where we have three nuture groups out of 8 classes: upper and lower KS3 (so 7/8 and 8/9 with year 8s going in the group that best suits their emotional maturity and academic level) and KS4.
I used to teach in a school which had them. Quite some time ago - it was pretty new at the time.
They were with the same teacher most of the time - 15 students, 2 classes, but came to other teachers for certain specialist things (I teach Drama - I had them once per week) I found it difficult. They had a wide range of learning and behavioural issues, and without full time support (which I didn't have) I found it difficult to ensure that they all made progress. I remember that the whole thing was deemed a success, and I think it was, in all fairness. There were two groups in Yr 7, then reviewed it and reduced it to one group in Yr 8, with the rest of those students joining mainstream classes. By Yr 9, they were all integrated.
