Coal Hill School
The Skovox Blitzer confronted the Twelfth Doctor in the school hall in the early 2010s. The Doctor used his sonic screwdriver to open a vortex, which swallowed the Blitzer. The TARDIS was parked on the stage. The Doctor revealed it to Danny Pink as Clara Oswald explained everything to him.

As the Skovok Blitzer didn't go far, the next day it re-entered the school hall through the vortex, and chased Clara out of the room. (TV: The Caretaker)

Coal Hill Academy
After major renovations to the campus in 2016 (TV: The Coach with the Dragon Tattoo) and a name change to Coal Hill Academy, the 2016 Autumn Prom was held in the main hall on 14 October. While preparing for the prom alone, a Shadow Kin pinned April MacLean's hand down. When Corakinus materialised, Miss Quill handed her a displacement gun, and instructed her to use it, but Charlie Smith knocked her out of the way before it could destroy her. While not killing Corakinus, his heart was sent out into space, and he began sharing April's. The three finished decorating for the prom the following day.

On the night of the prom, the Shadow Kin returned, and followed Charlie and Quill into the school hall, where all the students screamed and fled. (TV: For Tonight We Might Die)

The Coal Hill School Orchestra had a concert in the school hall sometime in 2016, between 7 PM and 1 AM. (TV: The Metaphysical Engine, or What Quill Did)
