He started in year 7 this year. I've occasionally needed to contact them as he has SEN and a couple of other minor issues.
If I send an email to general address they send an autoreply saying someone will get back within 2 school days (usually they don't and I have to send a chase)
If I phone it always drops to an answer machine and says someone will call me back - they don't even if I wait a couple of days then leave another message. There is only one phone number.
If I email class teacher or head of year they usually do get back within 2-3 school days...
But short of actually physically turning up there seems to be no way to contact them quickly. If for any reason there was a crisis at home or one of us was urgently admitted to hospital there would be no way to get in touch.
DD's school answer emails within a couple of hours and the phone nearly always gets answered on the first try
I'm probably being over anxious and hopefully we'll never need to get in touch in a rush but I'd like to know that I can if necessary.
