DD in Yr 8 at a GS, performing well so far as much as we can tell.
She has a friend not at the school who has recently passed 13 plus and now just has to wait for a space to open up.
I wasn't sure how much movement the school typically had. DP suggested that it was typical for GS's to discuss with parents of poorly performing students that an alternative school might be a more suitable option and encourage th to leave. This is more often before year 9/start of the schools gsce course. She seemed to think it was done at her school years ago and is still common practice at a number of schools now including DD's school.
I wasn't sure if this was rumour/myth or something that goes on in some or a number GS to, I presume to aid with maintaining higher exams results?
