Palm Glades Preparatory Academy and Palm Glades Preparatory High School opened this year on the same campus at 22655 SW 112th Ave., serving students in grades six through 10. Summerville serves students in kindergarten through fifth grade.

The Silver Palms campus at 23255 SW 115th Ave. is home to two schools serving students in kindergarten through 12th grade, records show. It is one of three Somerset sites in South Dade.

‘Saddened’

Somerset Principal Kerri Ann O’Sullivan said, “We are terribly saddened by this tragedy. Our hearts and prayers are with the victim’s family and everyone in our community impacted by this tragic event. The safety and well being of all students is of paramount importance to us.”

Ken Trump, a national bus safety expert who has trained South Florida school bus drivers, said they are taught the mechanics of driving vehicles, but need more training in other areas like crisis management, building relationships with kids and intervention.

“School bus drivers are often the first and last employees to see a student on a school day,” he said.

“Violence and conflict that happen in schools often start in neighborhoods and communities and the bus drivers are often going to be the first ones at risk of encountering that.”

Besides resources like security monitors and cameras, basic and ongoing training is needed for school bus drivers, whether they work for a district, charter or private company, he said.
