The kidnappers have since made contact with the family, saying the child was fine, and are demanding a ransom. Police hostage negotiators are among a team trying to help the family.
One parent at the school, Sharon Ragebult, said she was shocked by the incident.
"We've never had safety issues at this school. It's one of the best schools in the area," she told TimesLIVE.
She said the community, parents and police must work together and come up with a solution that would address the safety concerns.
An emergency meeting with parents has been called by the school for this evening.
