The full certification CAOHC course is 2 ½ days of instruction and practicum for those not previously CAOHC certified.

The one-day recertification refresher course is for those with unexpired CAOHC certification. Courses will be held at designated venues and times throughout the U.S.A.

Companies who prefer training at their site should simply indicate this preference on the form below and they will be contacted independently for arrangements. Upon successful completion of the examination CAOHC certificates are valid for a five-year period. CAOHC courses are designed to be product neutral but are permitted to show or describe products and services used throughout the hearing conservation industry.

NOTE: Those seeking recertification must ensure that their certificate is valid at the time of the course. If your certificate expires before the course is offered, an extension may be obtained by calling CAOHC at (414) 276-5338.
