- The initial Course Director exam fee is $200; the renewal exam fee is $150.
- The October 16, 2026 virtual workshop costs $500 separately, so workshop plus initial exam totals $700.
- Workshop plus renewal exam totals $650; eligible exam-only renewal is just $150.
- Failing both attempts means repeating the workshop and the exam, and paying for both again.
The Fee Snapshot: What CAOHC Actually Charges
The Course Director (CD) credential is issued by the Council for Accreditation in Occupational Hearing Conservation (CAOHC). It qualifies you to direct CAOHC-approved occupational hearing conservation (OHC) certification and recertification courses. Unlike many professional certifications, its published pricing is refreshingly simple: a short list of fees, all quoted in US dollars, with no tiered member and non-member rate structure published.
Here is the core fee picture for 2026, drawn from the reviewed public sources:
| Item | Cost (USD) | Notes |
|---|---|---|
| Initial CD exam | $200 | Online, open-book, delivered through the CAOHC Learning Center |
| Renewal exam | $150 | Used for renewal by workshop plus exam, or for eligible exam-only renewal |
| Virtual CD workshop (October 16, 2026) | $500 | Separate fee; eight-hour training session |
| Initial path total (workshop + exam) | $700 | Calculated: $500 + $200 |
| Renewal path total (workshop + exam) | $650 | Calculated: $500 + $150 |
| Eligible exam-only renewal | $150 | Requires meeting at least two qualifying renewal activities |
One caution: the $700 and $650 totals are arithmetic sums of separately published fees, not a bundled package price. If you see a bundled rate on a registration page, trust the page over this table, and confirm current amounts with CAOHC before you pay.
Why the Workshop Changes the Math
Many candidates focus on the $200 exam fee and overlook that the workshop is the larger line item. At $500, the virtual workshop costs two and a half times the initial exam. It is also the only path for those who need the structured instruction, because the workshop covers the five curriculum areas the exam is prepared around.
The workshop is an eight-hour training session, and it is training time rather than exam time. That distinction matters for budgeting your calendar. The exam itself is online and open-book, with saved progress and a ten-day completion window, so you do not need to block out a single long testing day. You do, however, need to protect the workshop date. Missing the October 16, 2026 session could push you into a later workshop offering and delay your credential timeline.
Costs Outside the Fee Schedule
The published fees cover registration. They do not capture everything a realistic candidate spends. Items to plan for, none of which come with a published price in the reviewed sources:
- Credential documentation. Your qualifying professional license or certification must be documented. If you must obtain copies, verifications or updated records, those costs fall to you.
- Verification letters. Supervisor and Course Director verification letters must be approved before ordinary registration. The letters themselves are free to request, but they depend on relationships you must build well in advance.
- Supervised course participation. Completing a supervised in-person or hybrid OHC course as adjunct faculty or practicum assistant may involve travel, lodging or unpaid time away from your regular job.
- Workshop technology. The workshop is virtual, so you need a reliable connection and a suitable workspace for an eight-hour session.
- Study materials. Reference materials, handbooks and practice resources are your own expense.
None of these are mandatory add-on fees from CAOHC, but together they can exceed the exam fee, especially travel for the supervised teaching requirement.
The Price of Qualifying Before You Pay
The largest "cost" of the Course Director credential is not on the fee schedule at all. Before ordinary registration opens for you, CAOHC requires a package of qualifications. In summary:
- A qualifying current professional license or certification.
- 1,000 relevant hours within five years, spread across at least three specified activities.
- A complete supervised in-person or hybrid OHC course experienced as adjunct faculty or practicum assistant.
- Credential documentation plus supervisor and CD verification letters, approved in advance.
For most candidates, accumulating 1,000 relevant hours is a multi-year investment of professional time. If your current role does not naturally generate hearing-conservation instruction, program management or related work, you may need to restructure part of your job or volunteer for committee and teaching assignments to get there. That is a real opportunity cost, and it is the reason the $700 headline number understates what the credential takes.
Eligible professions also warrant a check. Current web eligibility includes physician assistants, while the November 2025 policy manual list differs. If you are in a borderline profession, confirm your approval with CAOHC before spending anything on the workshop. Our CD requirements guide walks through eligibility and prerequisites in detail.
Key Takeaway
Get your eligibility approved before paying for the workshop. Because letters and documentation must be approved before ordinary registration, paying early without approval risks locking up $500 in a date you cannot yet use.
What a Failed Attempt Really Costs
The exam requires an 80% passing score, and you get two attempts within the ten-day window. That is more forgiving than a single-shot exam, but the consequence of failing both is steep: you must repeat the workshop and the exam. At published prices, that second pass through the full path is another $700 for an initial candidate, plus the time cost of scheduling a new workshop.
The open-book format lowers the stakes of memorization but raises the importance of navigation speed and judgment. Because the exam is open-book, the questions tend to reward your ability to locate and apply the right guidance quickly, so a candidate who arrives unprepared and plans to "look everything up" can still fail twice. For a realistic view of the challenge, read how hard the CD exam is and the breakdown of the CD passing score. Note that CAOHC does not publicly disclose a pass rate, so our CD pass rate article explains what can and cannot be said about outcomes.
Renewal Costs Over the Five-Year Cycle
The CD credential is valid for five years, so the true cost of ownership includes a renewal event. You have two routes, and the price difference is large:
| Renewal Route | Total Cost | What It Requires |
|---|---|---|
| Workshop plus renewal exam | $650 | Attend the workshop ($500) and pass the renewal exam ($150) |
| Eligible exam-only renewal | $150 | Meet at least two of four qualifying activities, then pass the renewal exam |
The exam-only route is the budget-friendly option, saving $500 over the workshop path, but it requires documented activity during your five-year term. You must show at least two of the following:
- Ten qualifying OHC courses directed.
- Two years of CAOHC committee or task-force service.
- Ten relevant continuing education contact hours.
- One approved CD workshop taught.
Do not misread the ten CE contact hours as a universal standalone renewal quota. It is only one of four options, and you need two of the four. Directing courses in the normal course of your work could satisfy the first activity at no extra cost, which is why active Course Directors often end up on the $150 route.
Extensions and Related Credentials
If life interferes, extensions of up to six months are available at CAOHC's discretion, but you must submit your request at least 30 days before expiration. Failed exams do not qualify for an extension, so an extension is a planning tool, not a rescue. Also note that renewing your CD does not renew any separate Certified Occupational Hearing Conservationist (COHC) credential; COHC renewal remains a separate process with its own costs.
Building Your Budget Step by Step
Rather than a single number, think of the cost as a sequence of gates, each with its own spend and decision point:
- Confirm eligibility. Verify your profession is approved and tally your hours against the 1,000-hour, three-activity requirement. Cost: your time.
- Complete the supervised course. Arrange adjunct faculty or practicum assistant participation in a full OHC course. Cost: travel and time away from work, if applicable.
- Secure documentation and letters. Collect credentials and obtain supervisor and CD verification letters. Cost: minimal, but plan for lead time.
- Pay for the workshop. $500 for the virtual session, October 16, 2026 for the current offering.
- Pay for the exam. $200 initial, taken online within your ten-day window.
- Reserve a contingency. Hold funds in case a repeat workshop and exam are needed.
Spending Prep Dollars Where They Count
Since a failed double attempt is the single largest avoidable cost, a modest investment in preparation pays for itself. The workshop curriculum is organized around five course topics, which map to the areas you should be fluent in. These are unweighted preparation topics from the issuer's course, not an official weighted exam blueprint, so weight your effort by where you are weakest rather than by a published percentage.
Domain 1: Developing OHC Certification and Recertification Course Curricula
Understand how an approved course is structured and how certification differs from recertification offerings.
- Curriculum design for initial versus refresher courses
- Aligning content with CAOHC course requirements
Domain 2: Course Director Procedures Before, During and After OHC Courses
This is the operational heart of the role, and open-book candidates should know exactly where to find procedural rules.
- Pre-course preparation and approvals
- On-site responsibilities and instructor oversight
- Post-course reporting and record handling
Domain 3: Effective Teaching Techniques and Hearing-Conservation Training Resources
Know how to teach adult learners and which resources support compliant instruction.
Domain 4: Federal Regulatory Changes Affecting OHC Courses
Stay current on regulatory shifts that alter what a course must cover, since outdated knowledge is a common stumbling block.
Domain 5: Scientific and Technical Advances in Hearing-Conservation Instruction
Be ready to discuss how new science and technology influence what and how you teach.
For a deeper look at each area, see our complete guide to the five CD content areas. When you are ready to organize your preparation, the CD study guide lays out a path, and our CD cheat sheet condenses the must-know facts for quick review.
A Lean Prep Plan Tied to the Fee Structure
Because your workshop comes before the exam, sequence your effort around it. The timeline below is a lightweight template, not a substitute for the curriculum itself.
Domains 1 and 2
- Review curriculum structure and course procedures so workshop discussion builds on a base
- Mark the procedural references you expect to consult during the open-book exam
Domains 3, 4 and 5
- Revisit regulatory updates and instructional advances while workshop notes are fresh
- Run practice questions to test recall and speed before opening your exam window
Controlled Execution
- Use the ten-day window deliberately, saving progress as you go
- Hold your second attempt in reserve; aim to pass the first time
Practice resources such as our CD practice tests are an inexpensive way to expose weak domains before you spend $200 on an attempt. Keep in mind that question allocations on practice material are editorial, since an official weighted blueprint has not been verified.
Frequently Asked Questions
For an initial candidate attending the October 16, 2026 virtual workshop and taking the exam, the published fees total $700: $500 for the workshop plus $200 for the exam. This excludes documentation, travel for the supervised course, and study materials. For background on the credential itself, see what CD certification is.
Renewal by workshop plus exam totals $650 ($500 plus the $150 renewal exam). If you qualify for the exam-only route by meeting at least two of the four qualifying activities, renewal costs just $150.
The exam requires an 80% score and allows two attempts within the ten-day window. If you fail both, you must repeat the workshop and the exam, so you would pay those fees again. A failed exam also does not qualify you for a renewal extension.
A member versus non-member fee distinction is not published in the reviewed sources. Confirm the current rate that applies to you directly with CAOHC before registering.
Yes. Expect indirect costs such as credential documentation, possible travel for the supervised in-person or hybrid OHC course, and your own study materials. The bigger commitment is the 1,000 relevant hours required within five years, which is time rather than money.
