Agencies

A Pscychical Investigation Agency is an organised group of psychically sensitive child agents who are most often (But not always) led by an adult supervisor, despite this not being a legal requirement.

Larger agencies tend to have more operatives, more teams, more supervisors, and even science teams such as those belonging to the Fittes and Rotwell Agencies who work to understand the science behind The Problem and invent technologies to make the world safer.

To legally operate an agency has to be registered with D.E.P.R.A.C., the conditions that an agency has to meet to become registered are unclear and have never been brought up in the series.

Purpose
The purpose of an agency is to locate and secure the sources of ghosts, either to make the world a better place or for personal gain.

Clients who believe they are threatened by a ghost, or simply want a ghost removed (As long as it's not on private property) may apply to agencies to have the ghost's source located and destroyed for a fee by trained operatives.

Agents
Almost all agents work for an agency, and while Freelance Agents are not unprecedented, they are rare.

They are the highly trained psychically sensitive children employed by an agency to do the dirty work of fending off the spirit, locating, and then disposing of the source.

They use a variety of tools to achieve this.

Supervisors
Supervisors are adult operatives with largely no psychic talent who normally hang back while agents locate the source, they are there to do what their name suggests, supervise the operation and assist if necessary.

Supervisors are very common among agencies, however they are not legally required to be present during an operation. They are only legally required to be present during an agent's training.

Uniform
Many Agencies have a uniform to help them stand out from others, however this is not a legal requirement to operate a D.E.P.R.A.C. Registered agency and is therefore mostly for branding.
