NICS Improvement Act sought to address gap in information from states about mental health adjudications/commitments prohibiting purchase of firearms. It authorizes grants for states to improve quality and completeness of records available to NICS, but to qualify for a grant, a state official must certify to ATF that the state has implemented a qualifying program permitting persons adjudicated as a mental defective, or committed to an institution to apply for relief from that firearms disability.
