The students, who were on a trip to visit Humboldt State University, came from a number of Southern California high schools.
Most of the students were from the Los Angeles Unified School District. Los Angeles Unified School District spokesman Tom Waldman said 19 students from 16 schools were on the bus that crashed.
Others on the bus included a senior from Valhalla High School in El Cajon. The Grossmont Unified School District said "we understand him to be safe and recovering from minor injuries." The student's followers on Twitter have been offering him well wishes.
