Ofsted has said delivering more in-depth inspections called-for by MPs would cost £8.5 million a year, and warned declining inspector pay means they are losing staff to academy trusts.
The watchdog has published its response to the Parliamentary education committee’s report on the impact of inspection.
The report argued a “nuanced” alternative to “totemic” Ofsted single-phrase judgments should be developed as a “priority”.
MPs also called for less frequent, more detailed inspections, a longer five-day notice period for schools and a review of the government’s coasting schools policy.
