CAOHC Questions and Answers

What is the CAOHC certification exam?

The CAOHC (Council for Accreditation in Occupational Hearing Conservation) exam certifies Occupational Hearing Conservationists to perform audiometric testing in workplace hearing conservation programs. It validates competency in pure-tone air conduction testing, otoscopic inspection, and OSHA 1910.95 compliance. Certification is required under OSHA's Hearing Conservation Amendment for technicians conducting employee audiograms.

What is the format of the CAOHC certification exam?

The CAOHC exam is a written multiple-choice test administered at the end of an approved 20-hour initial certification course. It includes both a written knowledge assessment and a practical hands-on demonstration of audiometric testing skills. Candidates must pass both components under the supervision of a CAOHC-approved Course Director.

How many questions are on the CAOHC exam?

The CAOHC written exam typically contains 50 multiple-choice questions covering hearing conservation fundamentals, audiometry procedures, and regulatory requirements. The practical portion requires candidates to demonstrate proper audiometer calibration checks, otoscopic examination, and a complete audiometric test on a live subject. Exam length varies slightly by Course Director.

What topics are covered on the CAOHC exam?

Topics include anatomy and physiology of the ear, noise-induced hearing loss, sound measurement, OSHA noise standards, audiometer operation and calibration, pure-tone air conduction testing, otoscopic inspection, standard threshold shift calculations, hearing protector selection, and employee training requirements. The curriculum follows CAOHC's standardized core content outline for Occupational Hearing Conservationists.

Who is eligible to take the CAOHC exam?

CAOHC certification is open to nurses, industrial hygienists, safety professionals, medical assistants, technicians, and other personnel responsible for workplace audiometric testing. There are no formal education prerequisites, but candidates must complete an approved 20-hour initial course taught by a CAOHC-certified Course Director. Audiologists and physicians are exempt from certification requirements.

How do I register for the CAOHC exam?

Registration is handled directly through CAOHC-approved Course Directors rather than a central CAOHC testing portal. Candidates locate an approved course via the CAOHC directory at caohc.org, contact the Course Director, and enroll in the 20-hour training session. The exam fee is typically bundled into the course tuition charged by the provider.

How long is CAOHC certification valid?

CAOHC certification is valid for five years from the date of successful completion. To maintain certification, technicians must complete an 8-hour CAOHC-approved recertification course before their expiration date. Recertification reviews updates to OSHA regulations, audiometric best practices, and refreshes hands-on testing competencies with a Course Director.

What are the best tips to prepare for the CAOHC exam?

Review OSHA 1910.95 hearing conservation standards, study ear anatomy and audiogram interpretation, and practice calculating standard threshold shifts with age corrections from Appendix F. Familiarize yourself with audiometer daily biological checks and proper headphone placement. Take timed practice tests covering decibel math, noise dosimetry, and hearing protector attenuation ratings before course day.
