ThreeTomatoes, my children are grown up now but when they were at a Lewisham primary school ten years ago Lewisham's banding procedures went like this:
- At the end of year 5 all children took the banding tests.
- At the start of year 6 the child's band was notified to the parents. There were five possible bandings: 1, 2A, 2B, 2C, 3. 1 was highest. The banding was done by ranking all the children by their total score in the tests and then labelling the top 20% as band 1 and so on down the list.
- Child's band was then automatically fed into the CAF so it was available when applications to Lewisham schools (and Greenwich, which was using a similar system) were being processed.
- Each school aimed to take 20% of its intake from each band. So in effect five separate admissions procedures were run in parallel for each school. They could be oversubscribed in band 3 and undersubscribed in band 1, for example. In those cases they would leave the Band 1 places unfilled rather than put children in from other bands - although there came a point in the late spring/summer when that went by the board and unfilled places would go to children of any band.
The effect of that system was that if the school managed to fill all its places in the right proportions, it would have an intake broadly comparable to the borough profile.
However, at Haberdashers' Aske's Hatcham, the system was different, more like the Harris academies described above. They tested all the children who applied (using a different test from Lewisham) and then allocated them to bands with reference to a national scale. So say a child got 182 they'd look at the scale they were using and say '182 - that means Band 2'.
Say they had 3000 applications altogether and 600 of them turned out to be from Band 2. They'd then say 'OK, that means this year we should allocate 20% of our places to Band 2 children'.
Now of course if they had 50% of their applications from children at the bottom end of the ability range then they'd end up allocating 50% of their places to lower ability children. But in practice they were getting a very high proportion of their applications from children at the top end of the ability range, so quite legitimately they were taking a very skewed intake, but were still labelled as comprehensive. The intake was representative of the applicants, but not of the borough.
Health warning: this may all have changed in the intervening years!
