Disclosed are methodologies, a system and components thereof and associated computer programs for providing training/testing of one or more users performing treatment of Sudden Cardiac Arrest(SCA) victims. The system provides computer controlled interactive instruction and testing methodologies that enable one or more users to be trained and/or tested using a plurality of mannequins including circuitry and hardware that enable each users compressions to analyzed for rate, depth and recoil to ensure that each user is performing the chest compressions properly. The data collected for determining rate, depth and recoil are collected via mannequin-specific hardware and electronics that utilize a plurality of magnets provided in proximity to a Hall Effect sensor. Data is collected at each mannequin and transmitted to at least one computer processing unit operating to receive, collect, analyze and display the data as well as store data for subsequent use in individualized training and certification of users.
