Spartan Academy was a former private, all-boys, boarding school in California. After the school administrators were convicted of giving answers to a clandestine society, the Immortals, it is demolished and all of their students were sent to Twin Branches High (then Centerscore High), a public school in Centerscore, California.
Its sister school was Monarch Prep.
- Every year, the school held a cotillion. Students from Spartan Academy would usually get a date from Monarch Prep. At the end of the cotillion, the Immortals would launch fireworks at the beach.
- Spartan Academy would annually hold the Spartan Games. In the Spartan Games, students would participate in a paintball battle against each other for $100,000 prize that will be used to fund the school however way the winner wishes.
