Well, I've found out his results. 128 in VR, 118 in NVR and bizarrely 114 in maths. So 3 points away in total. Yet his Year 5 maths results in the optional SAT's was a 5a.
Just goes to show, it what happens on the day.
The school are going to fully support an appeal, and seem to think that we have a good chance.
Experience has proved to me that there is very little correlation between the SAT's and the 11+ papers.
The former is designed as a building block which leads onto the syllabuses in subsequent Key stages 3, 4 and 5 and the latter is a measure of both inherent and tutored ability.
