A super selective means that they require above " just " passing the 11+
Using Kent Sevenoaks/Tonbridge/Tunbridge Wells area there are 6 grammar schools and 1 Academy with a grammar stream.
Of the 7 schools.
1 (the Academy) takes children who either passed with low pass (so around 360 for pass make) and children who just missed out (so down to about 350)
2 takes girls/boys *one is boys only one is girls only who passed the 11+
1 Has 14 Governors' places that went to girls scoring 411 or above. Most girls offered places at this school qualified on distance grounds - and a score above 410 (this school uses inner and outer circle I think inner is 3 miles radius)
1 takes girls who passed 11+ with those who lived in their " inner area" (from memory this is a 3 mile radios) needing a score above 408, except for one who came in with 407. The 40 places offered to girls living outside the local area required an aggregate score of 415
1 takes boys who passed 11+with a score above 411
Of the schools 4 will be viewed super selective and 2 will be viewed a selective.. The last is brand new and only started the grammar steam last year at the moment I do not know if people will call it selective or luck I have heard both claimed grin
1 takes boys who passed 11+ with a score above 418 (some got in with a score of 417 but not all)
As for scores the school who takes boys who passed 11+ and then on distance/parish in 2013 scored higher in their A levels than the school who takes above 411 so even with a super selective it is not a guaranty that there is a A plus A level.
