History
The "new" Governors were installed at Coal Hill Academy by EverUpwardReach Ltd. around the time of the spring 2016 renovations of the school grounds. (TV: Brave...ish Heart)

Shortly after the start of the Autumn term, the Governors built a robot to masquerade as an Ofsted inspector named Paul Smith, in order to evaluate Miss Quill's class. Miss Quill discovered their label in the robot's wreckage after it was destroyed by a skin-peeling dragon. She was intrigued as to who exactly the Governors were. (TV: The Coach with the Dragon Tattoo)

They arranged for Dorothea Ames to become the new head teacher of Coal Hill Academy, succeeding Frank Armitage. Ames claimed that the Governors were capable of removing the arn in Miss Quill's brain, which would free her from Charlie's control. (TV: Co-Owner of a Lonely Heart)
