Ofsted has rejected calls to automatically exempt education providers with RAAC from inspection, but urged leaders to use its deferral policy if they get the call.
In the autumn term, the watchdog removed all schools and colleges affected by the crumbly concrete from its inspection schedule.
But since January, these education providers have been eligible for inspection.
Geoff Barton, the general secretary of the Association of School and College Leaders, wrote yesterday to education secretary Gillian Keegan to request an extension of the approach.
