An oversubscribed secondary in my area normally has a big and very busy Open Evening each Autumn. This year they've announced they won't be having one, though it will still be possible to book on one of a very limited number of tours during the school day as an alternative.
In the meantime, Year 6 parents at neighbouring (and former feeder) primaries (all leafy) have been invited to a talk by the Headteacher of the secondary saying "This meeting will provide you with an early opportunity to discuss matters of mutual concern and interest about the process of secondary transfer and the induction of Year 7 students."
I've heard they held similar meetings in previous years (in addition to the Open Evening) and it was basically a preview of the Headteacher's Open Evening speech, but with more opportunities to ask questions.
Is this sort of favouritism allowed? My gut feel is it's probably completely legal, but surely it's a bit dodgy?
