What to stanines mean?

[lelly88]

I have just received an email giving me my DS' yr 9 CAT scores from the Senco. My DS has significant dyslexia, and is top 10 of top set in Maths and science. He had
Verbal 98 (5th stanine)
Quant 119 (8th stanine)
Non verbal 128 (9th stanine) (top 9th of pupils who take the test)

What is this stanine? I thought 128 was top 4%??

On my son's CAT score sheet it has stanine ranges:

1 = very low
2 & 3 = below average
4, 5 & 6 = average
7 & 8 = above average
9 = very high

I think that a Standard Age Score of 128 might equate to a National Percentile Rank of around 96th percentile which would be your top 4%.

Thanks, what is confusing me is that he says this is "top 9th" so that's not top 4% -more like 11%!! He's a math teacher.

Someone who is in the top 4% is also in the top 9th. Maybe you could get your son to explain it to you?

After googling a fair bit. I don't think stanines are the same as percentiles. Bit like apples and pears.

So arimaa can you explain how 1/25 is the same as 1/9, you seem to think thay are, please explain.
