Honolulu Department of Emergency Services spokeswoman Shayne Enright said the shooting happened at Roosevelt High School in Honolulu.
No additional details about the injuries or shooter were released. Police and Department of Education officials didn't immediately respond to messages seeking comment from The Associated Press.
An official who answered the phone at Roosevelt said the school was locked down.
About a half-dozen parents, including Carolyn Richardson, gathered outside the school after word of the shootingspread.
"This is really freaking me out," Richardson told The Associated Press.
Richardson said she learned about it around 9 a.m. through a text from her son, CarDarow, a sophomore.
Her son told her he heard shots had been fired at the school, but that he was OK. She then used her cellphone to video chat with her son. "I told him, I gotta hear your voice," Richardson said.
Other parents outside the school also texted and talked on their phones to their children.
