In reply to OP, in my primary school new members of staff are asked at interview about running an after school club; other more long standing teachers (incl myself) are expected to run an after school club because we are the more senior members of staff! (and I suppose should be setting an example!) Basically, if you want to apply to go through the threshold, you need to be running one! I don't agree with this pressure but with Ofsted looming on the horizon I suppose SMT think it reflects well on the school?!
