Abstract
PURPOSE: Emergency Medical Technicians (EMTs) provide lifesaving care to sick and injured patients. After completing a state-approved course with cognitive and psychomotor training, EMT certification requires passing the National Registry computer-based adaptive exam. This study examined whether delays in taking the exam are associated with failure and provides context on the EMT role and certification process in the United States. METHODOLOGY: Data included pass/fail results from 714 students who completed EMT courses between January 2013 and June 2025 at a large public university in Los Angeles County, California. All courses used similar curricula, equipment, facilities, instructors, and competencies. The study analyzed first-attempt exam outcomes relative to the time elapsed between course completion and testing. FINDINGS: Students who tested within 15-45 days had comparable pass rates, with the highest success among those testing within 30 days. Passage rates declined significantly after 45 days, and delays beyond 60 days were strongly associated with failure. These results indicate that the best chance of passing occurs when the exam is taken within 1-45 days of course completion. ORIGINALITY: This study demonstrates that delaying the National Registry EMT exam increases the likelihood of failure, particularly after 60 days. The findings can guide administrators and instructors in advising students to minimize delays and may inform curriculum adjustments to support long-term knowledge retention.
