What is the purpose of the course certificate?

Federal mandates require workers exposed to cotton, coal, and silica dusts to have spirometry testing performed by technicians with valid certificates from a NIOSH-approved Spirometry Training Course.

Students who successfully complete a NIOSH-approved spirometry training course will receive a certificate from the course director.

Certificates should be printed with a watermark and include the following information:

  • sponsor’s name
  • student’s name
  • dates and location of the course
  • NIOSH course approval number
  • signature of the approved director responsible for that course

Certificates can indicate the awarding of continuing education credit if this is granted by specific accrediting organizations.

The certificate may be requested as part of federal regulation site inspections and therefore must be retained by the student.

The course certificate is valid for 5 years. There is a 7-month grace period allowed after the initial or refresher training course 5-year expiration. After 5 years and 7 months, spirometry technicians must retake an initial 2- or 3-day course (a NIOSH-approved Refresher Course) in order to continue testing under mandated regulations.

To obtain duplicate copies of course certificates, individuals should send a written request to the sponsor of their course. NIOSH does not maintain copies of individual course certificates.

Licensure of health professionals is generally the function of a state board, and issuance of a course certificate does not imply that NIOSH has certified that student as a pulmonary function technician, nor does it imply that NIOSH warrants the performance of the student after completion of the course.
