Sleep Scoring Proficiency Exam
The American Board of Sleep Medicine (ABSM) Scoring Proficiency Examination is intended for applicants for the Sleep Technologist Registry Examination. Candidates applying under Pathway B (A-STEP program) or Pathway C (health professionals) must demonstrate sleep study scoring competency in order to qualify for the Sleep Technologist Registry Examination by participating in the inter-scorer reliability (ISR) program of an AASM-accredited sleep disorders center or by successfully completing the ABSM Sleep Proficiency Examination. The Scoring Proficiency Examination is provided at no charge for candidates preparing for the ABSM Sleep Technologist Registry Examination.
The Scoring Proficiency Examination is made up of 200 consecutive 30-second epochs from an actual sleep study. Scoring must be in accordance with the AASM Manual for the Scoring of Sleep and Associated Events. Each epoch requires four separate scores: sleep stage, respiratory events, periodic limb movements and arousals. Percentage agreement is calculated on an epoch-by-epoch basis. The threshold for passing is 85 percent agreement with the gold standard score.
Each epoch is presented as an image in your internet browser. Gain, filter settings and window size cannot be changed, but a magnifier is available for better detail. A 30-second and 120-second window is provided for each epoch. The 30-second window is recommended for scoring of sleep stage and arousals; the 120-second window is useful for scoring respiratory and limb movement events.
Details of the scoring system and examination-specific rules are provided on the starting page of the Scoring Proficiency Examination. You will have 48 hours to complete the examination. A timer is positioned at the top left of the page. You may retake the examination if you are unsuccessful. This is not a learning exercise – answers will not be provided.
