I've just finished reading this thread and as a secondary teacher I just want to put forward how the sub-group targets work from my school's perspective.
Class teacher - it is our job to ensure all children reach their potential, to flag up any starting to underachieve and to put forward interventions. Next week I will be going through my year 11 results and explain why there was any underachievement. I will also be creating my action plans for my new groups in regards to differentiation and additional support which may be needed. These are added to and changed as the year progresses and includes SEN, G&T, EAL and FSM.
HoD, HoY and management regularly meet to look at the data for entire year groups from year 7 up to year 11 to discuss what intervention is needed.
In my school results are generally really good and most sub-groups do really well, but we are still struggling with our FSM sub-group.
For example (these are rough figures for ease of mathematics, but not too dissimilar), there are 100 students in a year group. 15 have FSM. The data for a year group shows that 90% of children are achieving their predictions or better. Our value added is fab with children achieving 1 or sometimes 2 levels higher than statistics say they should.
This all looks great until we look at the 10 who are underachieving, sometimes by quite a lot.
1 child is in and out of hospital a lot.
1 child has suffered bereavement
The other 8 are FSM.
It is management's job to work out why these students are not achieving. We want all these children to achieve. The PP helps us to try different interventions to stop these children on FSM falling through the cracks.
You will notice that the other 7 students on FSM are doing absolutely fine, so intervention is not needed for them.
So we could look at the stats and say 90% of our students achieve their predictions or better and look wonderful, but we can also say that 50% of students on FSM at our school fail to reach their potential. This should not be the case. It is wrong that with a free state education system there are those who are failing due to poverty and deprivation. It should not happen. The teachers don't want it to and neither does the government hence PP.
