Josh Miller HEARTS Act

Josh Miller Helping Everyone Access Responsive Treatment in Schools Act of 2012 or Josh Miller HEARTS Act - Amends the Elementary and Secondary Education Act of 1965 to direct the Secretary of Education to award matching grants to local educational agencies (LEAs) to: (1) purchase automated external defibrillators (AEDs) for use in their schools, and/or (2) provide training to meet the grant requirement that at least five adult employees or volunteers at each school where an AED is to be used successfully complete training in its use and in cardiopulmonary resuscitation (CPR).

Requires LEA grant applicants also to demonstrate that: (1) the AEDs are integrated into the schools' emergency response procedures, and (2) emergency services personnel are notified of their locations.

Gives grant priority to schools that: (1) lack an AED; (2) typically have a significant number of students, staff, and visitors present during the day; (3) generally have a longer wait for emergency medical services than other public facilities in the community; and (4) have not received funds under the Rural Access to Emergency Devices Act.
