The Securing Aid for Every School Act establishes a federal grant program, overseen by the Attorney General, to significantly enhance security measures in elementary and secondary schools nationwide. This program aims to provide financial assistance to states and local educational agencies for a range of critical security improvements. A primary focus of the grants is to facilitate the training and hiring of veterans and former law enforcement officers to serve as dedicated school safety officers. States can use funds to create certification or licensure programs, which may include specialized firearm or de-escalation training, to prepare these individuals for their roles. The bill also permits the hiring of off-duty law enforcement officers. Furthermore, the grants support comprehensive physical security upgrades within school premises. Eligible activities include installing advanced access control systems like metal detectors and surveillance cameras, enhancing door security with automatic locks and peepholes, and reinforcing building exteriors with forced entry or bullet-resistant glass. Funds can also improve emergency responsiveness through increased lighting, emergency call boxes, and alert systems. The legislation explicitly prohibits federal interference in how states and local agencies utilize these funds, ensuring flexibility in implementing eligible security activities and training programs. Grants are to be awarded without discrimination based on a school's public or private status, religious affiliation, or existing school resource officer funding. An appropriation of $900,000,000 is authorized to carry out this vital program.
