Can someone please check my understanding.
In order to be considered for a grammar school place in bexley your child has had to score a 'selctable' score. this year this was 218. (which roughly equates to 76 %).
If the child scored in top 180 in the borough (this year 254 - which is roughly 90%) than he or she is guranteed a place.
Anything between 218-254 (ie 76%-89%) is all done by distance. Even if you are out the borough. So a child scoreing 77 % if living living closer will get priority than a child getting 88% if living further.
Is that right?
Yes, your understanding is correct. Except for Top 180, a Pass is a Pass (regardless of score) and the distance criteria comes into play.
Although, because the scores are standardized, they don't equate to the percentages you mention.
Hope that helps, it's such a nerve wracking time making the right choices. Best wishes.
