OHC Frequently Asked Questions
If I leave my current employer, does my Council for Accreditation in Occupational Hearing Conservation (CAOHC) Certified Occupational Hearing Conservationist (COHC) certification become my employer's property?
No, the COHC certification is awarded to the individual who successfully completes all the requirements for the credential. Even if an employer pays for the course and certification, the certification is awarded to the individual and only that individual can use the credential to perform audiometric tests and other responsibilities in the hearing conservation program. Other technicians, supervisors or the employer cannot use or share the COHC certification number. If you have concerns, contact the Professional Supervisor (PS) who is the licensed physician or audiologist providing oversight of your hearing conservation program (HCP).
Who is responsible for remembering the expiration date of the certification?
You are responsible for maintaining your certification since the CAOHC number is yours and not your employer's. You will receive a 6-month and a 1-year recertification notification from CAOHC.
Does CAOHC offer any extension on certification expiration?
All extension requests must be received by the CAOHC administrative office at least 30 days before expiration of the certification, subject to approval by CAOHC. This exception is intended for COHCs having difficulty locating a course in a specific geographic area, serious illness or other extenuating circumstances. To request an extension, go to the My CAOHC Account link on our home page.
What determines my expiration date?
The COHC certification expiration date is set for 5 years from the date you complete the course, not the exam.
How can I find my CAOHC certificate number and expiration date?
When your Course Director applies for a certificate on your behalf, you receive a congratulatory letter, a certificate for framing and a wallet ID card with your certification number and expiration date. You can also get a copy of your certificate by going to the My CAOHC Account link on our home page. If you have questions, contact the CAOHC administrative office at firstname.lastname@example.org or 414-276-5338.
Do I need a license as an audiometric technician in my state?
It depends on your state. Some state government agencies may claim jurisdiction over your actions as a COHC. For example, Oregon and Washington Departments of Labor require CAOHC certification for OHCs, while the Department of Health in Texas requires registration of all audiometric technicians, including COHCs.
Your state audiology licensure board may require audiologists to register COHCs as an audiology aide. Likewise, COHCs operating under the supervision of a physician are typically subject to a state's medical practice laws. To find out about your state's license requirements, contact your hearing conservation program manager or your professional supervisor (audiologist or physician).
Where can I find a job in this field, and what can I expect for compensation?
Jobs and wages vary greatly by region; check local resources. CAOHC does not have a job bank or salary data.
Is there an exam for the OHC course?
For both the 20-hour certification course and the 8-hour recertification course, it is required that participants pass a national standardized written exam in addition to practical examinations on audiometric testing and hearing protection fitting given during the course. Currently all exams are administered in the classroom by the course director and must adhere to specific standards and procedures.
The national standardized written exam for both the certification and the recertification are intended to address the following objectives:
1. Evaluate the level of knowledge obtained through the classroom experience.
2. Determine whether the student has gained sufficient knowledge to work as a COHC.
3. Reinforce course content and provide additional learning opportunities.
4. Standardize the student's course experience and enhance the credibility and value of the COHC credential.
How do I know if the course I am attending is CAOHC-approved?
Only approved courses are listed on this website have been approved by CAOHC. Also, a CAOHC certificate of course approval issued to the course director should be displayed at your course. If you do not see this certificate, ask for it.
How do I get Continuing Education Units (CEUs) for taking this CAOHC course?
If course directors wish to offer continuing education credits for their COHC courses, they are individually responsible for submitting all applications to the continuing education board for the association granting the continuing education credits, i.e. the American Association of Occupational Health Nurses, the American Academy of Audiology, the American Speech-Language Hearing Association, etc. CAOHC does not provide this service.
How do I find and register for a CAOHC course in my area? What does it cost?
CAOHC-approved courses are listed on this website. To find a course, visit the OHC Course Search Listings section. Contact the course director to register and obtain cost details, which will vary by course depending on instructor and location.
What is the difference between a Professional Supervisor of the Audiometric Monitoring Program (PS) and a supervisor/manager of the hearing conservation program?
According to the Occupational Safety and Health Administration (OSHA) hearing conservation amendment, the PS of a hearing conservation program (HCP) must be a licensed audiologist or physician. This professional ensures that audiograms for monitoring noise-exposed workers are correctly administered and interpreted. (See Scope of Practice: The Professional Supervisor of the Audiometric Monitoring Program). The PS advises the COHC. Conversely, a supervisor/manager of an HCP is typically a safety professional, human resources administrator or other management-level company personnel. This supervisor/manager is responsible for the HCP's overall management and effectiveness and may also directly supervise the COHC.
