CANTON — A controversial new security protocol that teaches staff and students to active­ly resist an armed intruder will be extensively reviewed by School Committee members, parents, and selectmen before students are actually trained.

“We are not ready to go ­beyond the point of training staff,” Superintendent Jeffrey Granatino said at a Canton School Committee meeting Thursday night, stressing that the school district is “under no time constraint” to implement the enhanced strategies, known as ALICE, right away.
