KNOXVILLE, Tenn. (WVLT) -- Knox County School leaders wants to know what lessons they can learn from the shooting at Inskip Elementary School last week.

"How someone could do this. Why someone would do this," Knox County School Board Chair Indya Kincannon said.

Superintendent Dr. Jim McIntyre announced Monday he wants to to create two working groups to re-evaluate two areas: safety and security policies, along with hiring and non-renewal protocols.

"This was a terrible incident last week and if there's lessons to be learned from it, we want to make sure we learn from them," McIntyre said.

4th grade teacher Mark Foster shot two school principals last Wednesday after learning his teaching contract wouldn't be renewed, police said.

"I think this raises some concerns around our whole hiring and non-renewing process," school board member Cindy Buttry said.

The district says Foster had passed standard background checks.

School officials later received an anonymous email, alleging Foster was a danger; however, a school security investigation ended with nothing to justify firing Foster.

"I'm not sure if there are policy issues that could have been better that could have prevented this. I'd like to think so, but I'm not sure, "Kincannon said.

School board member Sam Anderson said he wanted the district to focus resources on helping students, not just fixing human resource problems.

"No matter what we do, bad things will continue to happen to good people," Anderson said. "Where we can really help prevent this kind of thing from happening is to make sure we raise people who really care about Knox County Schools."

McIntyre said he plans to name the committee members in the next few days.

Regarding district hiring policies, McIntyre said he'd like to incorporate human resource experts from either the Y-12 National Security Complex or the Oak Ridge National Labs.

Parents will have a chance to talk with McIntyre and share their concerns during a community meeting set for Thursday night at 6:00pm.

The meeting is in the Inskip Elementary School gym.

Childcare will be provided, according to school officials.
