KenR, The quote from a previous discussion contains a number of inaccuracies. The Judd website does not say that the mean score is 120, it says that the minimum selective score is 120. The mean cannot be 120 or 50% of the children will pass. According to NFER, 11+ tests still have a mean of 100. The Judd website does say that 140 is the most

*common *score, which is true because it includes all those who would have scored 140+ ie those in the rh tail of the bell curve above 140. This may be where some confusion occurred.

Kent use local standardisation for their 11+, as you can see on the NFER website. This has to be the case, as 11+ candidates are mostly a self-selecting group of the most able children, so standardising them against the general population would just produce lots of 140s, not the spread required to differentiate between abilities. Local standardisation is why we can never work out how many age standardisation marks our children may get- it depends how clever the other children taking the test are (and specifically how clever those born in the same month are.) As NFER point out, the 11+ is standardised using the one and only group of children to take the particular test written for them.

If anyone is interested, I found this link while looking for something else.

It is from NFER, showing how they trial test questions to make up a bank to choose from for testing and makes interesting reading. So what happened to our NVR?? Makes you think they must make one of the papers in each year harder on purpose, then.......???
