Applied for HoD in my school. Deadline was a month ago. All 3 of us in the department applied and received letters a fortnight ago saying interviews would be the week after half term.
I emailed the principal today to ask if she had more details and was told the details would be out tomorrow after the deadline had passed.
So, it looks like they re-opened it for another month after our deadline and now my colleague and I think it suggests they aren't considering us at all and would prefer to hire someone external.
I wish they would just be upfront. I have already been told I will be going back to 0.6 if it isn't me who gets HoD. But the way this is being handled, especially if an external candidate is appointed makes me feel that I should really be looking for a HoD post elsewhere.
