The "Weapons Detector Systems in Schools Act" aims to enhance security in South Carolina public schools by mandating the installation of weapons detector systems at all public school building entrances and athletic venues. The bill requires that appropriate training be provided to staff and volunteers on the use of these systems and the protocols for responding to weapon detections. Additionally, it stipulates that all individuals entering these facilities must be screened by qualified personnel, with penalties established for those who refuse to comply. Until the full systems are installed, schools are permitted to use handheld metal detectors.

The legislation also tasks the State Department of Education with creating regulations regarding the selection, implementation, and maintenance of these weapons detection systems, as well as establishing standard protocols for their use. The definition of "weapons detector" is broadened to include metal detectors and any other technological means for screening for weapons, as deemed appropriate by the State Board of Education or local school district boards. The act will take effect upon the Governor's approval.
