Policies banning guns at schools create a place that "insane killers" consider "the safest place to inflict maximum mayhem with minimum risk," he said.
Former congressman Asa Hutchinson will lead the school security project.
Armed personnel will be part of the security model but not the only component, Hutchinson said.
"School safety is a complex issue with no simple, single solution," he said. "But I believe trained, qualified, armed security is one key component among many that can provide the first line of deterrence as well as the last line of defense."
The NRA, with its roughly 4.3 million members, is the standard bearer for protecting the Second Amendment. It is also the source of hefty campaign donations.
During the 2012 election cycle, the NRA donated $719,596 to candidates. Republicans received $634,146 of that, according to the Center for Responsive Politics' analysis of federal campaign data.
Some $85,450 went to Democrats, many of them in states that are considered more conservative when it comes to gun control laws.
The NRA's point man on its school security study, Hutchinson, received $7,000 from the organization for his 2000 congressional campaign, and $7,450 in 1998.
