ExploreAbout this exam
NIOSH-approved spirometry training prepares healthcare professionals to perform and interpret spirometry in occupational health screening. It is intended for nurses, respiratory therapists, technicians, and physicians who conduct lung function testing in workplaces, clinics, or mobile screening programs. The course emphasizes practical technique, quality assurance, and accurate interpretation. Training covers indications and contraindications, equipment calibration and quality control, participant preparation, coaching for acceptable maneuvers, acceptability and reproducibility criteria, reference values and pattern recognition, recordkeeping and communication, and infection control. Instruction typically combines lectures, hands-on practice, and a written examination. Because NIOSH approves individual courses rather than a single centralized exam, content and logistics vary by provider. Candidates should verify current requirements with their course provider and NIOSH directly. Preparation includes reviewing spirometry fundamentals, practicing coaching and maneuver technique, and understanding ATS/ERS acceptability standards. Many courses require participants to perform supervised spirometry tests and pass both practical and written assessments. The credential demonstrates competency in obtaining valid spirometry results for occupational health surveillance, but it is not a license to practice independently. Continuing education and refresher training are often needed to maintain skills. Candidates should confirm the specific course objectives, prerequisites, and completion criteria before enrolling.
What you'll study
About NIOSH SSS preparation
What is the difference between NIOSH approval and certification?
NIOSH approves spirometry training courses that meet its content requirements; it does not administer a single national certification exam. Course providers issue documentation of completion. The term "NIOSH certification" is often used informally, but candidates should confirm the exact credential and its scope with the course provider.
How long is the training course?
Course duration varies by provider. NIOSH-approved courses typically span one to three days, depending on whether they include practical skills practice and assessment. Contact the specific provider for the current schedule and hourly requirements.
What does the written exam cover?
The written exam samples all domains: indications and contraindications, calibration and quality control, participant preparation, coaching technique, acceptability and reproducibility criteria, interpretation, recordkeeping, and infection control. Expect scenario-based questions that test applied judgment, not just recall.
How difficult is the practical skills assessment?
The practical assessment is usually the most challenging part. You must demonstrate correct coaching, recognize unacceptable maneuvers, and achieve reproducible results with a volunteer or simulator. Candidates who practice hands-on technique and review acceptability criteria thoroughly tend to perform best.
What happens if I fail the exam or practical?
Retake policies are set by the individual course provider, not by NIOSH centrally. Some providers allow one retake after remediation; others require repeating the full course. Ask your provider about their specific retake policy before enrolling.
How should I prioritize my study time?
Focus first on maneuver technique and acceptability criteria, which carry the most weight in practice. Then review calibration and quality control, interpretation, and infection control. Practice coaching aloud and reviewing sample curves. Use the course manual and ATS/ERS standards as primary references.
What are common reasons candidates struggle?
Common pitfalls include weak coaching that leads to suboptimal effort, failure to recognize back-extrapolated volume or early termination, and misapplying reference equations. Candidates also lose points on calibration documentation and infection control details. Practicing full test sessions with feedback helps prevent these errors.
How much does the course cost and how long is the certificate valid?
Fees and certificate validity periods are set by the course provider and can change. NIOSH does not publish a single fee or validity period for all courses. Check the provider's website and NIOSH's spirometry training page for current details.
Is there a formal application or eligibility requirement?
Eligibility requirements vary by provider. Many courses are open to healthcare professionals and technicians who perform spirometry. Some providers require prior clinical experience or employer sponsorship. Confirm prerequisites with the course provider before registering.
Where can I find official information?
Visit the NIOSH website for a list of approved spirometry training courses and current requirements. The course provider's site will have logistics, fees, and schedules. Always verify details directly with these official sources, as policies and offerings change.
