CAT scores between 89 and 111 are considered to be average.
GL Assessment (who publish CATs) have three
'above average' categories:
112-118 (the so-called stanine 7)
119-126 (stanine 8 )
127+ (stanine 9) "very high"
It could be argued, therefore, that once you're into stanine 8, you're just entering the 'well-above average' band.
If I remember correctly, Kent used to have a minimum 11+ individual score of around 115 (don't know if it's changed), so you can see that 116 might be a bit borderline by that measurement.
Would you like this thread moved to Kent?
