The head of Ofsted’s curriculum unit, Heather Fearn, is leaving the watchdog to take up a directorial post at Ark Schools.
The senior HMI will become director of curriculum and assessment at the academy trust in September.
The shake-up comes as Ofsted’s strategy director also announced his departure from the inspectorate this week. Chief inspector Amanda Spielman’s tenure ends this year.
Fearn has worked for Ofsted for the past six years, during which she set up Ofsted’s curriculum unit, including overseeing its subject review inspection process.
