Five people were taken from the crash scene to hospitals in good condition, Emergency Management Services Authority spokeswoman Lara O'Leary said.
Those taken to hospitals were the driver and four students, including a sibling who rode to the hospital but did not have injuries, Kennedy said.
A parent took another student to a hospital, Kennedy said. All those taken to hospitals were treated and released, she said.
The bus driver, Flynn Lee, has worked for the district since March 2011 and was treated for neck and back injuries, Kennedy said.
Students initially told school officials they were wearing seat belts, but they were not, Kennedy said.
A fire official said there were special needs children on the bus, but Kennedy said she could not confirm that information due to privacy laws.
