The Today Programme emailed me (they don't know I'm nuts) because of a story in the news claiming that some schools are breaking the rules regarding admissions policy. These schools allegedly ask parents naughty questions about their marital status or financial background, and some apparently even ask for money. Read about it here
My own view is that any Head who doesn't do all of this and more is a complete fool. I've seen it done loads of times (but usually with more subtlety) and I'm sure you have too.
Anyway they would like to talk to anyone who has any experience of this and they assure me that all communication will be treated in the strictest confidence. (Make sure you get them to confirm this in writing and don't enter any naming competitions either)
If you want to tell them anything then email email@example.com (Put ‘schools’ in the subject header).
