I'm a bit late with this one - been moving house (flitting I suppose I should say!) drama getting internet etc.
Have sent out an audit sheet to staff at school but replies are few so far. I fear I'm not going to get many, I don't think Scots is at the top of anyone's list at the moment - everyone is getting geared up for our return inspection!
From my own observations, I think most of us in the English department teach some Scots texts - but the level to which we focus on the language varies. There are a fair few teachers who definitely speak Scots in and around the school but don't actually teach it. I would say the majority of our pupils are happy to speak Scots but would not be confident writing it. There are a few of us who are really keen to have a real focus on Scots novels, short stories etc. We are trying to include Scots texts in units we are creating as we refresh our curriculum.
As far as I'm aware we don't have a Scots language policy in school and I haven't heard any rumours about one being put in place. This is something I will look further into.
We do teach Scottish Studies - but it is currently being taught in Social subjects, so their focus is not on the language particularly - I taught it a couple of years ago and did focus on the language, used Scots texts etc.
Hopefully there will be some teachers in my school who are keen on Scots being taught who will help with the audit.
