Inspectors carry identification (ID) badges
These include a photograph of the inspector along with their name and identification number.
The names of the inspection team will be given to you during your phone call with the lead inspector the day before the inspection begins. Check these names against their ID badges when they arrive.
There's no requirement for you to take a copy of the information on the ID badges, but they must be worn by inspectors at all times whilst visiting your school.
If you have a no-notice inspection, the lead inspector will usually phone the Ofsted regional office on arrival. You should raise and discuss any concerns about the identity of your inspectors at this point.
Inspectors will have been DBS checked by Ofsted
They don't tend to carry their DBS
