HOD here. No disrespect to supply teachers - what many have to put up with in schools is terrible - large double classes crammed in together, covering any and all subjects outside their specialism, kids who play up because it's 'just a supply', lack of support from SLT for behaviour issues. Don't even get me started on pay and conditions......
However, I do laugh at the idea of keeping a list of names of good supply in my little black book. I have not had a decent supply teacher in my subject for years. Even specialists applying for permanent posts are thin on the ground, and supply teachers in my subject area are as rare as hen's teeth. We have had long term supply in to cover several maternity leaves and long term sickness in my dept over the last decade. Not one of them was any good. Following the most recent changes to the GCSE and A Level spec the supply teachers really struggled with the content. I had no choice but to timetable them onto GCSE classes, but they just did not have the up to date subject knowledge to do it properly.
I have spent hours and hours trying to support long term supply cover. I provide everything - lesson plans, lesson materials, assessment materials. I support with marking, assessment and moderation - all of this and trying not to let my own classes suffer. I am exhausted.
The point I am trying to make SammyScrouge is that much as I would love to be able to get together a list of good supply to choose from there is no one to put on the list. In the last year having ANY supply in has been nothing short of a miracle. I have had to resign myself to hope for people to cover lessons who can at least manage behaviour.
It IS a babysitting service. My exam results do suffer as a result. I wish I lived in a part of the country where good, reliable subject specialist supply teachers were in such abundance that I could keep a list of them to chose from.
