I am glad this issue has been raised, as requiring potential recruits to be observed in their own schools is discriminatory practice. In the past few years, I have been a supply teacher, a teaching assistant and unemployed, so have been unable to apply for any posts which have stated in the advert that candidates will be observed teaching in their own schools (I have seen quite a lot of these over the past few years). Due to my lack of job, I am now doing yet another course of study!. I think it says a lot that when I was applying for teaching posts, I never seemed to get invited to interview when a school was a significant distance from my base in the West Midlands- one head even phoned me up wondering if the reason I had applied for a post in his school was that I might have family in the area (er... no, I just wanted a post in which I could finally start my NQT year!).
