We introduced 4 Matrix about a year ago - The system really helped with the summer analysis and I was able to use the Press Release and Research Groups in my report to Governors in August. Staff can use it to focus their intervention right down to group and individual level, which is where we find it is most powerful. We have a sig- KS2 PA cohort, so a lot of our students are in the target C/D group and every little thing we can do to help identify intervention helps!
