As for Chelmsford County High for Girls,

Thank you for this useful info. For CCHSG, is anyone able to tell me what the standardised scores of 420 and 217 are roughly equivalent to in percentage terms? Ie. 420 = 85% correct, or something. Obviously ignore age weighting for the purpose of this calculation. Thanks

It doesn't work like that - the girl whose standardised score was 420 could be a September 1st birthday who got c.60 in each paper, or an August 31st birthday who got whatever raw scores plus the uplift for '365 days younger' converted to 420, or any of many possible combinations of scores in each paper.

You could have a look at the thread with membets' reported raw scores, DC's month of birth and standardised scores for the most recent exam to get an idea of what combination of scores gave various standardised scores.

The score is a direct reflection of how the student compared with others in the tests. They can have a good standardised score even if their raw scores are low and vice versa. 420 means they are in the region of top 0.8% (taking age into calculation). 217 would mean they are at the 3 percentile. Imagine 300- 310 is median, I.e. 50 percentile.

Hi there

I'm looking again at the anonymised raw results for CCHSG:
https://csse.org.uk/wp-content/uploads/ ... -Entry.pdf

I hope no offence is taken, but I was really curious to know what could potentially be the reasons for some of the outlier scores at the lower end of the scale. Ability aside, could there potentially have been issues with calculating the correct answers but misaligning the correct option on the answer sheet? With respect to those children and with sympathy, I can't imagine it would be down to a lack of ability as even an untutored child who had never sat a mock would at worst surely score over 10 out of 60. Have there been instances of children not being able to cope with the exam and simply not completing the pages?

Again I was just curious to know, and this is in no way downplaying these children's abilities...just curious as to what could have potentially caused some of these results.

If you have a look at the sample material on the CSSE website, I think you will find that the potential for 'misalignment is very, very low.

Perhaps you are thinking of the CCHS CEM exam papers?

There has been quite a campaign locally, at least, for more DC to have a go at the exam, in an attempt to encourage more Southend pupils to try for the Southend grammar schools (it's the same exam for all the CSSE schools). So some DC will probably doing just that, despite never having a snowball in Hades' chance of doing well enough to qualify. Also, some will go to pieces in the exam and either get lots of questions wrong, or just not answer many. Or any at all. Once you have started the exam, you will have a raw score - even if it is 0 / 60 on each paper - which will be plugged into the randomisation formula and will come up with a standardised score for you.

Thanks ToadMum, yes looking again now at the past CSSE papers it does seem very unlikely that there would be any misalignment, unlike on a multipe choice answersheet.
