The whole point is that there is no advantage or disadvantage according to age.
If 2 children, one 10 years 1 month, the other 11 years, do the same tests and both score lets say 80%, the will have different marks due to the standardisation process. So the older child needs to get a higher % in the tests to get the same mark. This is fair, unlike virtually every other test they do, in which the older child gets the advantage of their increased development and experience.
The problem is, that as far as I can find, there is no information available on how strong the standardisation is. In other words, what the difference is in % terms between pass marks at the various ages.
To add complication, there is an appeal process, and borderline pupils may benefit from higher SATs scores etc, giving an advantage to older pupils. In our area (Wirral), it seems like a large proportion of pupils get through via this route, rather than with a straight test pass, so when you take the process as a whole into account, there is probably a bias in favour of the older pupils after all.
