The IHS Distance Learning for Professionals in Hearing Health Sciences course is designed to provide the foundational knowledge necessary for independent professional practice when coupled with hands-on training. Each book included in the course, the Professional Training Textbook, Professional Training Workbook, and the Trainer Manual, are included in the list of recommended reference materials for the ILE. 

In fall 2022, a new edition of the course is being released. This new edition may include some information that differs from what is included in the 2016 edition of the course (the blue and orange books). Below is which edition of the course should be used to study for the ILE at which time.

ILE Testing Year Edition to Use

2022 2016 Edition

2023 Either 2016 or 2022 Editions

2024 2022 Edition

The 2016 Edition of the course will be supported through May 31, 2023. Students enrolled in the 2016 Edition of the course must finish their studies and earn the Certificate of Completion by May 31, 2023. After that time, only the 2022 Edition will be supported. More information can be found on the 
2022 Edition page.


How long do I have to complete the course?

Students must complete the course by May 31, 2023 to receive the Certificate of Completion.

What is the average time it takes for a person to complete the program?

This is an independent, self-study course and you set your own pace. It’s totally up to you whether you want to cram and get it done in a few weeks, or utilize many months to complete the course. However, students must complete the course by May 31, 2023 to receive the Certificate of Completion.

What does the course entail?

The course is 40 lessons. At the end of each lesson, there is a test.  Please note: Lesson 26: Hearing Instrument History does not require a test. Lesson tests are taken online. Results can be viewed immediately so you can see which areas need to be improved upon. There are no pass/fail results on the lesson tests; just do your best. The 39 lesson tests prepare you for the cumulative 100 question final exam. 75% is a passing score on the final exam. You may re-take the final examination as many times as necessary.

Can IHS provide the correct answers to the cumulative final exam?

Unfortunately, we cannot provide correct answers because it would jeopardize the integrity of the course.

What happens after I pass the final examination?

After you have taken the final exam, you will receive instant score results. If you have passed, you will earn a Certificate of Completion, which is electronic. It is your responsibility to forward documentation to your local licensing body, if required. Students must complete the course by May 31, 2023 to receive the Certificate of Completion.

What else should I know about the state/provincial licensing process?

All questions surrounding licensure should be directed to your local licensing body.

My licensing body requires that I have a mentorship/apprenticeship. How do I go about obtaining one?

You may be responsible for locating a hearing aid specialist that agrees to mentor you. You may use the Directory located on the IHS website to search for a hearing professional in your area.
