The Inspector

The Inspector was a robot, labelled as the property of the Governors, who was sent to Coal Hill Academy to evaluate Miss Quill under the guise of an Ofsted inspector named Paul Smith. His Ofsted nametag would expire on 24 March 2017. He was destroyed by the leaf dragon, revealing his true nature to Quill. (TV: The Coach with the Dragon Tattoo)

He was later revealed to Miss Quill by Dorothea Ames to be expensive and difficult to replace. (TV: Co-Owner of a Lonely Heart)

Behind the scenes
On 9 November 2016, the official Class Facebook page released an image of the Inspector's report on Miss Quill.

Among events seen in The Coach with the Dragon Tattoo, the report mentions Quill calling the Inspector "a s***, w******, and a f*** h***".

It is shown that the Inspector marked Quill inadequate and gave her level fours in every section of his assessment.
