That AI ad is vair interesting.
Nice option for schools to second someone, have ofsted pay their wages for a bit, and have an unqualified TA and a couple of supply hours to cover the workload... Bit of a cost saving for the school if they do it right.
(with the added impetus that the school would then have an ofsted inspector on roll.
)
Win, win, really. (except for, um, the kids and the unwanted experienced AIs, and the teachers and other staff picking up the slack, but y'know.)
The whole thing is frankly bizarre, and I can understand the op's frustration.
The governor thing is interesting, especially with the appointment of head teachers. I find it difficult to square that 'civilians' are capable of running the selection process for a new HT, and choosing one, for a school, (which usually includes an assessment of the candidate's teaching skills in a planned lesson) but that someone with 18 years experience of the same is deemed less capable. And an ofsted inspector isn't the one hiring or firing. Funny old world.
I hope you find an equally fulfilling appointment elsewhere, op.
