Another student - a 15-year-old girl - was said to be in a 'fair condition' after being shot in the wrist.
Three other people - including two students - are thought to be have suffered minor injuries.
In a statement quoted by the Los Angeles Times, the LAPD said: "At this time, the information suggests that this was an isolated incident, involving the negligent discharge of a firearm, where innocent children and a staff member were unfortunately injured".
A handgun is also reported to have been recovered at the scene.
LA Mayor Eric Garcetti, meanwhile, said in a statement: "I am praying for the students shot today at Sal Castro Middle School, and want to express my deepest gratitude to the faculty and first responders whose quick, courageous action prevented this tragedy from becoming far worse.
