About Self-Study Lessons

Self-study lessons help you maintain your IAHCSMM certification by providing ongoing education to keep you up-to-date on the latest information in central service. Each lesson features a three-page article exploring a practical, central service-related topic and a 20-question exam. You will receive two points from IAHCSMM for every self-study lesson exam graded by Purdue University that you complete with a score of 70 percent or higher (14 out of 20 correct). Two attempts to achieve a passing score are permitted per examination. You can expect to study two hours on each lesson.

Six new self-study lessons are published annually, from March to January, here on the Purdue Digital Education Web site and in the IAHCSMM Communiqué magazine. Each lesson is valid up to three years after the publication date.
