The grant, the second awarded to the district through the department's Project School Emergency Response to Violence program, will support the district as it works to restore a safe, healthy environment in its schools, the federal agency said Monday.
Adam Lanza shot and killed 20 first-grade students and six adults at Sandy Hook Elementary School before shooting and killing himself on Dec. 14, 2012. Before he went to the school, the 20-year-old shot and killed his mother at their home.
The money will be used for additional grief support services; interventions for students identified as needing assistance for post-traumatic stress reactions and other other behavioral and functional problems; tutoring for students showing an academic fall since the incident; security; and other items.
"We will do whatever we can to continue assisting and supporting the healing and recovery of Newtown," U.S. Education Secretary Arne Duncan said. "This additional grant will help students, teachers, families, school district and community move forward after such an unimaginable tragedy."
