There are schools out there that simply can’t recruit adequately. There are lots of factors that impact this, leadership and management, funding, location for example.
So what are HMI/OFSTED doing to help with these?
If staff retention is an issue, HMI should be looking into why, and could be providing support to address and resolve.
If staffing is difficult to attract because of funding or location then the DfE (on behalf of HMI) can direct training providers to place staff in these schools (billions has been spent on contracts for Teach First, Ambition and lots of other local and national providers)
Going around driving school leaders to leave the profession (and at the very worst a Ruth Perry scenario) with their narrow judgements helps no one.
Everyone in education should be committed to the central mantra of giving kids the best start in life. HMI/OFSTED/DfE shouldn’t be separate from that, and when it fails culpability should also rest with them.
