After successful completion of an approved EMS education program, candidates are initially given three attempts to pass the cognitive examination (provided all other requirements for National EMS Certification are met). If a candidate is unsuccessful on an exam attempt, they may apply to retest 15 days after the last examination. After three unsuccessful examination attempts, EMT, AEMT, and Paramedic candidates must submit official documentation verifying the completion of a remedial training program. Remedial training is designed to provide candidates additional education and to improve their performance on subsequent examination attempts. After a remedial training program is complete, the candidate is given additional attempts to pass the examination (provided all other requirements for National EMS Certification are met). Candidates who fail to pass the cognitive exam after a total of six attempts are required to complete an entire state approved education program.
