NIOSH-Approved Spirometry Training courses offered at the University of Washington (UW) incorporate the most recent American Thoracic Society and European Respiratory Society (ATS/ERS) spirometry testing procedures and interpretation standards. The ATS is the leading medical professional society in the United States that provides evidence based statements for pulmonary function laboratory standards, testing procedures, and the interpretation of test results. Both the 2-day initial and 1-day refresher spirometry classes are offered on UW campus or can be conducted at your site.

The 1-day refresher course is designed for experienced spirometry technicians who have completed a NIOSH spirometry certification course within the last five years. Documentation of a valid NIOSH Spirometry certificate is required. Technicians with certificates older than five years must repeat the initial 2-day course to maintain their certification.
