ABIM SM Practice Test with Latest Exam Questions 2026

The ABIM Sleep Medicine certification exam assesses physicians who diagnose and treat sleep disorders. It covers normal sleep physiology, insomnia, sleep related breathing disorders, central disorders of hypersomnolence, circadian rhythm disorders, parasomnias, movement disorders in sleep, and the interpretation of polysomnography and other sleep studies.

Because Sleep Medicine is used by employers, boards and credentialing bodies as evidence of competence, preparation deserves a structured plan. Most questions are written as short clinical scenarios, so understanding why an answer is correct matters more than memorizing lists.

It is worth looking at what sits inside each topic area. Normal Sleep and Variants focuses on sleep wake mechanisms and neurophysiology; scoring and staging; and normal sleep across the lifespan. The Circadian Rhythm Sleep Wake Disorders area includes delayed/advanced phase, non-24-hour and irregular rhythm disorders; and shift work disorder and jet lag disorder. Questions on Insomnia typically involve chronic insomnia in adults and children; insomnia related to behavior, medical conditions or drugs; and short term insomnia. Central Disorders of Hypersomnia covers narcolepsy types 1 and 2; insufficient sleep syndrome, idiopathic hypersomnia, Kleine Levin syndrome; and hypersomnia due to medical/psychiatric disorders or medications.

Preparing for the ABIM-SM exam requires not only understanding the exam topics but also practicing with exam style questions. Our Sleep Medicine exam questions in practice tests help candidates review key concepts and familiarize themselves with the format and difficulty of exam.

At Killexams.com, our team works to maintain up-to-date practice content for exam preparation. We continuously review and refine our question sets and explanations to cover the latest relevant syllabus areas and help learners strengthen their understanding of core topics before facing the official exam. These Practice tests allow you to identify areas where you need improvement by measuring your readiness, and provide you exam questions to polish those areas.


By using our ABIM-SM Practice Exam PDF and Test Engine, you can practice a structured set of questions and answers that ensure your readiness to face the difficulty of exam. Wherever possible, content includes detailed explanations to clarify reasoning and support deeper learning.

The exam is computer based multiple choice and includes questions with polysomnography tracings. Practice scoring and interpreting sleep studies, and review treatment options for obstructive sleep apnea and narcolepsy.

The exact number of questions, the time allowed and the passing score for ABIM-SM are set by ABIM and can change when the exam is revised, so check the current candidate information before you book. Plan your pacing around those figures once you have them, leaving a few minutes at the end to review flagged questions.

One effective way to prepare for ABIM-SM is to work through the sections in order. Start with Sleep Related Breathing Disorders, which carries about 20% of the exam, and then Insomnia at about 17%. Spending your first weeks on the heaviest sections gives the biggest return on study time. After that, move through Normal Sleep and Variants; Circadian Rhythm Sleep Wake Disorders; Central Disorders of Hypersomnia; and Parasomnias, keeping short notes of definitions and examples for each. Before booking, make sure your practice scores are steady across every section rather than strong in only one or two.

Many candidates preparing for ABIM-SM find that spaced repetition works well for facts such as drug classes, lab values and diagnostic criteria, while case based practice questions build clinical reasoning. Combine both, and leave the final weeks for full length timed practice.
