South Bay students were taught how to defend themselves during an active shooter drill at the San Jose Unified School District.
The district's 32,000 students went through the 25-minute drill inside classrooms Thursday morning.
"Obviously the safety of our students is important to us and so the drill is part of taking that precaution," said Jorge Quintana, San Jose school district spokesman.
The annual drill was called after the Columbine school tragedy in Colorado in 1999.
Students in the San Jose drill were taught to run, hide and if necessary defend.
"They said that if the guy tries to get one of the students to jump on top of the man," said Alyssa Herrera, a 6th-grade student.
District officials for safety reasons did not want to discuss how they are teaching students to defend themselves.
