maximum possible mark

[roger123geegee]

Hi, I'd like to give my 11+ survivor a little reward based on his overall % of the standardised score.
In order to do this I would need to know the max possible std score.
Or, as i'm a bit thick today, would the result be the same as working out the overall % from the raw score data we actually get in the post.

Is it possible to know the max std overall score?

I've just read on another thread that someone thinks the highest score possible is 420. I boggled when I read that there were some candidates who scored in excess of 400!

Thanks.. That's hard going on a ten year old.

Based on what I have seen...

The highest score for 2013 entry posted in these forums was 395.224.

The highest score posted in these forums in the past five years is 396.627.

Hi,


Just read on another thread that it was the CSSE who advised a forum member that a small number of children scored in excess of 400.


This is very worrying for me as I felt my son stood a reasonable chance of securing a place at KEGS (out of catchment) with a standardised score of 372.298

372 is a fantastic score.

Apply anyway. You have nothing to lose.

It is meaningless to work out a % like this after the raw score has been standardised. Reward his effort not his score

Three standard deviations is said to represent 99.7% of a population. This equates to a score of 390. Only half the population is above the central point of 300, so 0.15% score above 390. Four standard deviations would be a score of 420, which includes 99.9% of the population.

0.15% represents 6 children out of the 4000 who took the exam, hence a bit pointless to go beyond a score of 390.

Hi CardyMow,

In which thread you have read this ? Can you please post that thread here ?

Thanks in advance

Perhaps someone else should check with CSSE. Another further confirmation would be good I was just as surprised this year (and still am).
