There are two adjoined rooms in the School. The kids in the left room have some basic information about the game of Pokémon. On the table is a notebook with notes on Trainers written inside. Status conditions and their effects are listed on the chalkboard at the back. In the room on the right, there are two School Kids on a blue carpet who will ask the player to battle. There is a reward for defeating them both.
In Pokémon Diamond and Pearl, on the player's first visit to the School, Barry is situated at the back of the room, reading the chalkboard. Upon talking to him, the Parcel is delivered. Two Town Maps are found inside the Parcel, and Barry will give the player one.
A teacher from the school can be found in a hidden section in the northern section of Route 204 that can only be accessed by using Cut. She will give the player TM78 (Captivate) for finding her.
