N.E.R.D.S (National, Espionage, Rescue and Defense Society) is a group of international spies that are 5 6th Grade Nerds in Elementary School. The Nerds are always getting picked on because they're nerds. N.E.R.D.S. contains children with considerably "nerdy" upgrades. It is mentioned that all N.E.R.D.S. are automatically retired when they turn eighteen, which is the legal consent age for adults. The headquarters is under the main setting, Nathan Hale Elementary, in Arlington, Virgina (Jackson comments that it is a "geekopolis"). In the fourth book the NERDS members are at a new school and they have a new playground.
