11 Plus Exams Forum

Can anyone tell me what percentile a maths score of 111 would be in Ashford, kent? I have found plenty information on percentiles and age standardisation but having difficulty working out the answer.

I may be the only person not really understanding your question, but possibly not as you have had no other replies...

111 in what maths test?

If that's a standardised 11+ score then 111 is around the 63rd percentile.

If it's a standardised CATs score then it's around the 75th percentile (and equates to about 120 on the 11+).


The standardisations are done nationally so it's impossible to say how Ashford may differ from the national distribution although it is well known we have fat tails in Kent but I doubt it would change things by more than a percentile or two at that point of the distribution.

Sorry. I should have said its an 11+ standardised maths score. My only reason for mentioning Ashford was to avoid information relating to west kent as I believe its different there. Thank you for your response.
KCC have sent me the raw score and I have calculated the percentage from that. I have asked them what raw score my daughter would have needed to pass the test at her age ( I'm assuming she will be classed as age 11 as she was only 2 weeks away from her 11th birthday. Can anyone think of anything else I could ask KCC which might be useful to know in order to get a more accurate result from them?

for standardised scores you usually take age as years and number of complete months, so she will be 10 years 11 months

Thank you.

F.Y.I.

That's a percentage which is not the same as a percentile. The two are not related in any useful way. You need the standardised score and the moments of the distribution to calculate the percentile.

Thank you. I will see if I can find out that information.
