This Is Why We Teach: A Stellar CAOHC Training Experience, in Their Words

For many occupational health professionals, hearing testing and audiometric monitoring is a box to check, and obtaining the required certification can feel the same way. We hear this all the time: folks seek a course that’s not just informative, but clear, engaging, applies to in the real world, and (heaven forbid) is genuinely enjoyable. A course where participants leave feeling confident - not overwhelmed.

Unless you have a direct recommendation from a colleague, finding an excellent, engaging CAOHC certification course can feel like a rolling the dice.

That’s why student feedback like this means so much to our team. Here is a direct message we received from an attendee of a recent 20 hour Initial CAOHC Certification course:

"I thoroughly enjoyed the CAOHC Certification Course. I was the trainer for my company, and I have attended several of virtual trainings. Earmark was by far the absolute best virtual training I’ve attended, and I dare say one of the best trainings - virtual or not!

Your instructions were clear, your study and class materials were incredibly helpful and the content was very interesting. I knew exactly what to expect the whole time. I was really blown away by how wonderful this program was, and how much I loved the content.

A training program is only as good as the instructors though so I do want to give you all the kudos you deserve. Hannah did an amazing job keeping us all engaged and breaking down some of the more difficult topics into bite sized pieces that we could more easily comprehend and digest. She was incredibly thoughtful when answering questions and overall very pleasant to learn from. I liked how Hannah was able to tell stories that applied to the topics in a relevant, engaging way that helped give some real-world examples of what we may encounter instead of leaving it all on the slides. She was also just really fun to have leading class! Juan was also very engaging and his contribution was impactful. I really liked his analogies and the variety of experience he brought to the table. Juan had a very pleasant demeanor and a way of explaining some of the tougher concepts in an easy to understand way. Frank was very engaging, made the class very comfortable, and laid out very clear instructions for each step along the way. I feel like you’re pretty set with who you are at this point, but please never change your dad jokes! It kept class fun and exciting. Your knowledge shone through and I am always impressed with people who can weave jokes into training but not loose the importance of the material. Your analogies and real-world stories were very helpful especially when it came to retaining the information.

One thing I loved about class was that we had three instructors. It kept things fresh and easier to maintain attention. I know you said you appreciate constrictive feedback because it helps you improve, but honestly I have nothing but 5 stars for this team. Thank you so much for your time. Your passion for the subject and the topics you taught really shone through.

From our entire team, we would like to extend a heartfelt thank you for taking the time to write such a thoughtful and detailed reflection. Feedback like this doesn’t just feel good to read - it validates the intentional choices we make in how we design and deliver our courses.

This Is Why We Teach This Way

Everything highlighted in this review is by design, and truthfully takes a considerably amount of effort and resources to maintain. We structure our CAOHC course around a few core principles:

Engagement over passive learning
We keep the focus on discussion, case examples, and real-world application. These analogies, stories, and examples aren’t extras—they’re essential for retention and application on the job.

Multiple instructors, multiple perspectives
Having a team teaching approach keeps the course dynamic, fresh, and easier to stay engaged with throughout.

A comfortable learning environment
People learn better when they feel at ease. Yes, even a well-timed dad joke has a role to play. Please notify your instructor if you are allergic to lukewarm humor and other types of cheese.
