Hi, I was hoping someone could help me. I'm looking at stats on all / low / middle / high prior attainers, but I can't find anything that explains what this is and how I can use this information to compare schools, in particular grammar schools versus independent schools.

I can see for example in 2018 all / low / middle / high prior attainers were as follows: -
Ribston: 9.9 / No Entries / 9.4 / 9.9
Cheltenham College: 1.2 / Not Published / Not Published / Not Published

If anyone can help that would be much appreciated - thanks.

It would depend on the cohort, but for those taking GCSEs who would have had the old 'levels' for SATs, Middle = 4, Low = below 4 and High = 5+

Presumably, for GCSE cohorts who took the 'new SATs', it's Middle = 100 - 110 / EXS, High = 111 - 120 / GDS, Low = <100 / Not Met?

Generally, for a grammar school, you would expect mainly High prior attainment. CLC probably has too few state school joiners at age 11 to make the figures meaningful.

Prior attainment related to Sats results so many Indie schools will be excluded.

Ribston has no low attainers only 8 middle attainers and the rest were high attainers in terms of Sats results. The 9.9 figures relate to the number of GCSEs taken so expect some take more than others which is why you don’t end up with round figures.

I assume that CLC's '1.2' indicates that they take mainly IGCSEs?

Just realised also assuming 'Ladies' as well - probably because the comparison was with a girls' school...
