With recent school shootings very much on their minds, some Tredyffrin-Easttown Middle School parents are taking aim at T/E’s response to an alleged threat of gun violence and bullying.

They sent e-mails, made phone calls, met with school officials.

Then, scores of them showed up at a school board meeting Monday night.

The district was ready. Message received, loud and clear.

The Superintendent announced the creation of parent focus groups to evaluate T/E’s threat-response policy and suggest changes as needed. He said the district will also explore “best practices” of other districts across the country and review relevant research.

And the day after the meeting, the principal of T/E Middle School sent an extraordinarily detailed e-mail to parents explaining how, as a parent himself, he takes students’ safety personally.

The hubbub started in early February. It simmered, then boiled over last week after a TEMS family, the Nissenbaums, told their story to the AP.

And it ran in newspapers across the country.
