The training and trial room on level 3 is a large space set aside for employees of the Accidents and Catastrophes department in order to continually work on their skills, or try out some experimental charms for assessment and tweaking purposes. While the room was originally charmed to behave much like the Room of Requirement within Hogwarts, this is no longer the case. Instead the large room is relatively empty, though there is a large pool in one corner for practising water-based charms work, and some heavy duty crash pads in another corner so that if you are levitating yourself, anyone else, or working with objects that are otherwise breakable, dents and bruises won't be an issue. These crash pads are also useful for those who wish to duel as part of their training and trialing.

If you need anything else within this space, you are expected to either provide it yourself or speak with your Department Head if it is something a little more questionable, large, or dangerous. Many muggle items are available in storage for charmswork (including a few automobiles), and you may indeed find some items within the storage cupboard on the other side of the department.

While this room is intended for use primarily by level 3 employees, those who work in other departments may make use of this space with a written request and approval from Maddox Quigley, Accidents and Catastrophes Department Head.
