Our federation of schools has a nurture group provision, shared among 11 schools in the area. Qualified teacher plus very experienced (10+ years) TA.
The children can only go to nurture group if they meet certain criteria. They stay for 2 terms, although I know of a child who stayed for 3. On entry and again on exit, the criteria are assessed to see if the nurture group has made a difference to the child.
Ive sat in on a session (with my governor hat on) and its amazing how the staff operate.
To give an example, we had to play a listening game, where each person told the others something good that happened that weekend. You get a good idea of the level of neglect for the children just from listening. (highlight of weekend: Playing COD with dad. CHild is 6)
Then the children had to go round the circle again, and say "Im thinking of someone who had a sleepover this weekend" and the children would all guess who. SO teaching turn taking, listening and speaking.
When the children said something happy, the teacher would say how she felt happy and look, her eyes were all scrunched up and her mouth turned up at the corners and thats how we knew she was happy. Teaching facial expressions.
The session broke for breakfast at 10am, as several children did not come into school with full tums, so they had toast. One child laid the table, another got the butter and spreads...each child selected their own topping and spread it themselves (life skills) and then on to free play and then a structured craft activity involving sharing and co-operating and talking in small groups.
Our nurture group does not teach as it is infants level and the skills of listening and turn taking, co-operating and social play and expression are what is needed to be taught. FOr many children, this is all they need to be able to cope in a classroom setting further down the line.
We have issues with TAs in our school that have been there since Noah built the ark. They cannot be sacked, they wont retire and they are next to useless. Others are brilliant, and take on essential roles like Speech and Language development, under the supervision and guidance of a bought in SALT.
