President Trump is planning to move ahead with his contentious proposal to provide firearms training to school employees and intends to establish a federal commission to examine other proposals, like his suggestion to raise the age to purchase some weapons, White House officials said on Sunday night.

But the administration’s efforts appeared to be piecemeal and of limited scope, falling far short of the language Mr. Trump has used for weeks about the need to end the scourge of school shootings, including at a dramatic meeting with relatives of victims of the Parkland, Fla., massacre.

In a call with reporters, the White House laid out a series of proposals that it said Mr. Trump intended to pursue to increase school safety.

The White House said it wanted to partner with local officials to provide “rigorous firearms training” to school personnel, including teachers and other volunteers who want such training. Mr. Trump first proposed the idea shortly after a gunman killed 17 people in Parkland last month.
