CIA

The CIA or the Central Intelligence Agency of the United States of America is a civilian foreign intelligence service tasked with gathering, processing, and analyzing national security information from around the world. It is a real organization, but in Spy School, it is comprised of fictional characters. Unfortunately, like many other organizations dedicated to justice, it is overrun with moles and double agents, rendering the Agency itself not fully trustworthy. In real life, the amount of employees is classified. Its budget is also classified. The agency has resources to almost everything the government can offer.

CIA Academy of Espionage
It also has a junior agent academy called the CIA Academy of Espionage, which is where most of the Spy School series takes place. They are the main organization of the series. Many of their enemies are classified or not disclosed to the protagonists.

Department of Misinformation
The Department of Misinformation is a department in the CIA. They are tasked with misleading people who are close to discovering the truth about the CIA Academy of Espionage. In some cases they are not able to fool them and instead recruit them, like Mike Brezinski.

Federal Witness Protection Program
The Federal Witness Protection Program, though not actually a part of the agency, plays a big role. The program relocates people who have been wrapped up in crime to safehouses across the United States. It is run by the U.S Marshall Office. They have a strong presence in Florida.
