The Council for Accreditation for Occupational Hearing Conservation (CAOHC) online verification system allows the public and current and prospective employers to verify if an individual holds a current CAOHC credential.
This system can also help certified occupational hearing conservationists (OHCs) check the expiration date of their credential and ensure their information is correct.
