OK. Thanks. I'm in West Sussex. I'l ask the WSCC tomorrow. Reason is my boy has been offered a contract (which I am trying to understand) teaching guitar to groups of kids on p/t basis. Contract says he must teach 10 lessons per term (per school) but not more than 33 in any academic year. So I rather guessed this was one per week which is why I asked about number of weeks in a year. d
