Coates Academy (most commonly referred to as "Coates") is a private, elite boarding school, situated close to Perdido Beach. It is where troubled or "difficult" children are sent by their mostly rich parents. This implies that all students at Coates are relatively intelligent. Major characters that went to Coates include Caine, Diana, Drake, Taylor, Computer Jack, Brianna, Bug, and Dekka. There is a slight rivalry between the children at Coates and the children at Perdido Beach school.
The location of Coates is referred to as "up the hill". The path up the hill to Coates has been described as more of a mountain than a hill. The school's interior is described as being dull and gray. The tiles in the lunch room are arranged to an arrow pointing up.
- Before the FAYZ
Because children were sent to Coates due to their problems, many of the children hide the stories behind why they were sent there.
Coates is used as a base of operations for Caine and his followers. They hold an operation to see what happens when somebody poofs. They held Andrew in place and forced him to use his powers, to see if it would counter poofing. Jack catches it on a recording, giving them an insight of what happens when one poofs.
Caine continues to use Coates. Lots of kids had changed over to Sam's side. Orsay travels there with Drake. Drake uses the headmistress' office as his.
When Caine and the remainder of those loyal to him leave for San Francisco de Sales Island, Coates becomes empty. At some point in the books, Howard begins to use it as a base for his alcohol (and supposedly drug) operations.
Coates remains as a base for Howard and his illegal activities. It is also where Astrid goes to hide Little Pete from the Human Crew, and where Little Pete dies.
Coates becomes deserted once again when Howard is killed by Drake. It is not referred to after this.
