Re: Age standardisation in Kendrick/Reading
I agree that the publication of raw scores would be helpful but totally agree with the idea of standardisation.
Not only have the older children been exposed to more vocabulary (up to a whole year) etc but older children are also much more likely to be put in higher sets at school from early primary which means that they have been exposed to more challenging work for longer. Not to mention the confidence that comes with being in the 'top' sets. So, yes, I am totally for standardisation. You could argue that they don't do enough to re-balance this difference. There was a FOI request (Kent) a couple of years ago that showed that a much larger number of September borns pass the 11+.
Anyone who has issues with standardisation should read Gladwell's 'Outliers'. Sobering stuff.

Re: Age standardisation in Kendrick/Reading
I think age standardised pattern should be disclosed to public. Many people working hard for years.
Re: Age standardisation in Kendrick/Reading
I like this topic.We keep say there is no +/- in the total score.
Did enough due diligence on this last few days comparing my ds raw or standardize score from various borough results. I see there is an impact/difference.
Probability of impact is less hence it is not treated as a major issue.

Re: Age standardisation in Kendrick/Reading
At least in Kent, doesn't make much of a difference... it varied by perhaps 1 std score difference for someone aged 10y10m/10y5m (this was for maths).. Also saw this reply from Kent Council:
There is a limit to the detail I can give, because we have an agreement with our test provider (a company which also carries out the national standardisation which is applied to Kent pupils’ results) that we will not share information which is regarded as commercially sensitive, and this extends to the standardisation process. If “ball park” information will help, though, the standardised score for each birth month puts the raw score in context with the performance of children the same age. If – as is often the case – older children slightly outperform younger ones when the test is trialled, the standardisation will reflect that, in that a slightly lower number of correct answers will yield a slightly higher standardised score for a younger child. The less the effect in trialling, the less the adjustment. The effect of standardisation is generally that a child at the August end of the range will get a slightly higher standardised score than a child at the September end, even if they got the same number of right answers. Usually the greatest range across the year group in an 11+ paper is 6 points, but with the tests we are using at present it is typically less than that.
