Key Stage 5 Value Added errors after update 188.8.131.52/184.108.40.206 (November 2018)
After applying updates 220.127.116.11 and 18.104.22.168 (November 2018), the key stage 5 Value Added tool may appear 'broken' and the following may be seen:
1) Yellow/orange warning triangles throughout the VA tool
2) All pupils have the same estimates as each other in the same subject
3) Value Added scores appear to be much lower than before
The reason for all of the above is because we have added the DfE's latest methodology for KS4 APS which is now based on 9-1 points, not QCA points. This is how VA is calculated in the provisional Ready Reckoner, issued in October 2018, for the 2017/18 Y13 cohort.
