I meant the appeals held after the review process is over. I found in the leaflet:" Should your child not qualify at review, if you wish, you will be able to ask for an independent admission appeal for a place at a particular grammar school after the allocation of school places in March. Admission appeals will be heard from May 2015."
Ah, I see what you are asking now.
Yes, because the Appeals (as opposed to Reviews) are now held following allocation, and some schools will be oversubscribed, they are essentially heard for an individual school. However, if the school is undersubscribed, there is no Group hearing, and the order of business goes straight to the N/Q hearing.
Would these appeal panels consist of staff members from the particular grammar school that someone would appeal to?
Absolutely not! These are Independent Appeal Panels (IAPs), and consist of 3 members of the public. (At least one lay member, and at least one non-lay member.)
What happened last year? What was the percentage of successful appeals at different grammar schools?
We don't have the statistics by school, only the overall rate of success (as at August 2014):
Grammar school (Unqualified after review)
137 cases heard
33 (24%) successful
Grammar school (Unqualified with no review)
39 cases heard
12 (29%) successful
