I would always go and have a look round. I had an interview for a DHT job once. I was so excited, everything seemed ideal but when I had a walk round I was filled with dread, the classes were divided by shutters and tiny. The offices were in a separate part of the school. These were the things I had very little control over. It all felt wrong and I am glad I didnt get the job. When looking for HT role, I would go and have a look round, have a good think about how the school made me feel, could I work with the staff, do a bit of digging, have a drive past at the weekend etc I don't think I would compromise, in my part of the world there about 12 primary headships going at the moment and HT conferences are like a Saga holiday-I would say hang in there until you feel it's right for you.
