It's possible. Here's the detail. I wrote to each of the schools in May, asking for the number admitted under each criterion and for the cutoff distances and scores, both for the start of the school year (Sep) 2008 and allocation day (Mar) 2009.
Parmiters' responded on 17th June with two sets of figures, merely labelled 2008 and 2009. The figures labelled 2008 I assumed were the Sep 2008 figures I had requested, and they showed plausible movement from the figures they supplied me in June last year. It may be that the figures labelled 2009 give the position at the time they wrote, i.e. June, rather than March.
WB responded on 3rd June. For numbers admitted and the distance cutoff, they gave two sets of figures, labelled Year 7 September 2008 and 2nd March 2009. However for the cutoff scores, they merely gave one set of figures, without indicating what time they referred to. Since some of the cutoff scores are higher than the corresponding March 2008 cutoffs they gave me last year, I presume they cannot be for Sep 2008, but cannot be sure they are for Mar 2009. I have written to the school asking for clarification, but have had no response.
