The BLS Instructor Essentials Course is taught in a blended learning format. AHA BLS Instructor candidates must complete the online portion, followed by the hands-on session conducted by BLS Training Center Faculty. Prior to taking this course, candidates must have a current BLS Provider course completion card. Candidates who successfully complete the BLS Instructor Essentials Course, followed by course monitoring, will receive a BLS Instructor card, valid for two years. BLS Instructors are then able to teach the BLS Provider course and any course within the Heartsaver portfolio.
