would you recommend sending your children to the school you work at? we wouldn't be able to afford private secondary and I'm worried that state school might be an awful shock for my son if he spends 6 years at my school first. He's still in nursery now.
I have done and it was fine. It is fairly accepted that your DCs will come to your school, and it makes life a lot easier in terms of commuting, matching holidays, and assemblies/plays/sports. We had a rule in our house not to talk about confidential stuff or gossip at home, and to treat DDs the same as everyone else at school.
what skills/experience/mindset do you think heads look for when hiring?
I think they are looking for overall competency to do the day to day job. They will want you to support the ethos of the school. Do some research into the Prep School Baccalaureate and Common Entrance.
I'm not in it for the money, but I have to live...do you know any way to find out the salary a school pays? And if you are interviewing, is there ever any leeway for negotiation or is it just stated when you are offered the job?
A top prep school will pay market value for your experience. If you are mainscale that will be around 40k, I imagine. When I recently worked in a prep school, they offered me 34k, and I said I couldn’t accept that, and they upped it to 38k. This was via an agency.
Good luck!
