A first aid instructor teaches cardiopulmonary resuscitation (CPR) and basic life support skills to students through classes and workshops. Your students may need first aid or CPR certification for their job, a volunteer position, or simply due to personal interest. Your job duties include scheduling class times, coordinating locations, transporting equipment and supplies, teaching the approved curriculum, reviewing safety standards, and evaluating student performance. You may have to give and grade an exam, and you must provide signed certificates of completion for your students once they master the first aid and CPR techniques you reviewed.
