LAKEVILLE — All visitors to Freetown-Lakeville school buildings must be escorted by a staff member, one of several protocols emphasized in the wake of a Nov. 17 school security breach, Superintendent of Schools Alan Strauss told members of the Freetown-Lakeville Regional School Committee at their Dec. 7 meeting.

“No one under any circumstances will walk alone in our buildings,’’ he said. 

Visitors will also be required to show a driver’s license as a form of identification; state their name and purpose for the visit, which will be checked, and wear a name tag at all times while in the building, Strauss said.

The discussion followed an incident in which Kayla Farris Churchill of Freetown, the parent of two children in the school system, was able to gain access into Apponequet Regional High School and the Freetown schools by saying she was there to pick up a student, whose name she made up.

She walked through the schools unimpeded despite providing a fictional name for the student she was picking up. She said she attempted to enter the schools to “test the security.’’

Compliance with security measures is crucial, Strauss said. 

“All protocols are only effective if they are followed fully,’’ he said in a solemn voice tinged with emotion. He said he responded to the breach “with anger, deep disappointment, frustration and immediate concern for the well-being of our students and staff.’’

The security breakdown resulted from “human error,’’ he said, and “was unacceptable on many levels.’’

Funding has been “put in motion’’ for strengthened security, including a system that takes a visitor’s license, checks if that license holder has a criminal background or is a sex offender, and then, if the visitor is cleared, creates a label that reflects the image and information on the license, Strauss said.

He called this system “another vital piece of security.’’

School safety has been a focus of administration and local public safety officials “long before the breach of Nov. 17.’’ Work has been done to secure all school vestibules to ensure that visitors enter two separate sets of doors, he said.

After entering the first door, visitors are then trapped in the second doorway until they can be safely allowed into the building, he said. 

The district has also secured a company to provide a free security assessment of each building. Combining this outside firm with local public safety agencies represents the “perfect combination,’’ Strauss said.

Lakeville Police Chief Matthew Perkins assured the community that the “safety of the kids in school is a top priority of the Police Department.’’ He said that minutes after his first meeting with Strauss, who was hired as superintendent earlier this year, the new school chief was describing security as an urgent concern and offering his assistance.

Lakeville students represent the largest population in a building in town during the day, Perkins said. “We train for the worst,’’ he said. “We take it very seriously.’’

Safety officials must have a “positive paranoia,’’ Lakeville Deputy Fire Chief Pamela Garant said. The department undergoes numerous safety drills, she said, and anticipates potential scenarios and how to mitigate them.

A safety committee, with a membership representing the select board, school committee and police and fire of both towns, will meet regularly to review security issues, Strauss said. 

“There were mistakes that happened that we are swiftly working to prevent from ever happening again,’’ Strauss said.
