Those in charge of the region’s public schools said they aren’t sure what changes might be in store for their security policies and procedures in months to come.

But locally and across the country, officials at schools and other institutions centered on children have begun to evaluate their plans in light of last week’s shootings of 26 students and educators in an elementary school in Newtown, Conn.

“As with any time we experience a tragedy, it’s going to bring up a number of questions that schools need to consider,” said Jeff Schuler, superintendent at Kaneland School District 302. “And it begins with how, potentially, we can make our buildings safer.”
