How normal is it for an independent school to appoint a new Head/Principal without any process at all? No advert, interview, shortlist... just an internal appointment and no other candidate considered at all. It was just announced as a done deal at the end of the holidays. It's not "acting head" while they do the process, it's a permanent thing.
It's a bit odd isn't it?
If there's an inspection, is it something the inspectors are likely to pick up on?
Is it even allowed under the guidelines of the professional bodies such as ISA, etc?
Would you be worried and start looking around for a new school? The lack of transparency bothers me a lot.
