Hi All,

Could anyone please help me?. I’m looking to find out what raw scores equate to the minimum pass mark of 303 as we are in catchment. I appreciate it varies every year just looking for a guide. Many thanks. Hoping someone can help.

This is the calculation:

Standardised score = (((raw score - mean) /standard deviation) x 15) + 100
Total score = 1.5 x standardised Mathematics + 1.5 x standardised English. (from a thread from 2014)

And here are the mean scores and standard deviations for the 2018 entry papers (from the 2018 collated cut-offs thread):

English (% since from 2012 to 2014, the paper was marked out of 50, but from 2015 out of 60)
____________________ 2012 ____ 2013 ___ 2014 ____ 2015 ____2016 ____ 2017 ____2018
mean ________________46.0____ 37.4____ 49.3_____ 55.3 ____ 50.8 ___ 47.2 ____ 67.1
standard deviation ____ 13.8____ 14.2____ 13.8_____ 14.4 ____ 9.2 _____8.1_____ 8.7

67.1% of 60 = raw score of 40.26

Mathematics (% since from 2012 to 2014, the paper was marked out of 40, but from 2015 out of 60)
____________________ 2012 ____ 2013 ___ 2014 ____ 2015 ____2016 ____2017_____2018
mean ________________ 54.1____ 54.6____ 52.1_____ 63.9 ____ 59.9 ____58.3_____54.1
standard deviation _____ 20.4____ 17.7 ____ 20.5 ___ 17.8 _____12.8 ____ 12.0 ____ 11.2

54.1% of 60 = a raw score of 32.46

Applying a bit of trial and improvement, I calculated that

• an English score of 36 plus Maths of 36 would have given a standardised score of 296.094

• an English score of 36 plus Maths of 40 would have given a standardised score of 304.13

• an English score of 38 plus aMaths of 37 would have given a standardised score of 303.275

(I think! - feel free to chip in and tell me I must have gone horribly wrong somewhere ).

Thank you. Looks like 60% minimum in both papers. Best crack on then

Thanks for the explanation, ToadMum - the leap from 2017 English to 2018 English seems massive! Must have either been a much easier paper than previous years, or a much stronger (in English at least) cohort? I haven't seen the paper (the most recent one we have is the 2017 intake Ishiguro one) but I'd love to know how such a big difference came about??

Hi,

I had one daughter sit the 2017 paper and one the 2018 paper. Both of mine are very strong in English. The 2017 paper was a lot harder than the 2018 English paper. My middle daughter came out saying it was a lot easier than any of the practice papers she had sat.

Hi ToadMum,

I wonder if you can help. My daughter had a practice using the 2015 CSSE papers. She scored 42/60 raw on English and 45/60 on maths. I've tried several times to work out the standardised score using your figures above but am getting way-out results. I wondered if you could kindly calculate it for me please. Thank you.

Do you mean the paper sat in September 2015 (for 2016 entry), or the paper sat in September 2014 for 2015 entry?

The 2015 paper for 2016 admissions.

Thank you.

I make it 344.1 (anyone else, please pitch in ):

Mean (E) = (50.8/100)*60 = 30.48

(((42 - 30.48)/9.2)*15) + 100 =118.78

Mean (M) = (59.9/100)*60 = 35.94

(((45 - 35.94)/12.*15) + 100 = 110.62

(118.78 + 110.62)*1.5 = 344.1
