- ADCI's Air Diving Supervisor exam is administered online, not tied to fixed regional testing windows like some other credentials.
- You need 200 field days as an Air Diver, 50 working dives, and 30 days as an Assistant Supervisor before you're eligible.
- The $275 fee covers both the examination and the certification card once you pass.
- Certification is valid for five years, with applications and renewals processed through Skill N Depth.
The Scheduling Reality: No Fixed Testing Windows
If you're used to certification programs that publish quarterly testing windows or specific "exam season" calendars, the Air Diving Supervisor certification from the Association of Diving Contractors International (ADCI) works differently. This is an online ADCI Air Diving Supervisor Certification Examination, and there isn't a published set of 2026 testing dates the way there might be for a proctored, in-person credential. Instead, scheduling is driven by your own eligibility timeline and the administrative process behind the exam and card issuance.
That means the real "exam dates" question for most candidates isn't "when does ADCI open registration" - it's "when will I actually meet the qualification thresholds and have my documentation ready." Get that answer wrong and you can delay your own scheduling by months, regardless of what any calendar says.
Building Your Eligibility Timeline Before You Book
Before you can even think about a testing date, you have to hit the field experience thresholds. These are the numbers that actually govern your 2026 timeline:
- 200 field days as an Air Diver
- 50 working dives as an Air Diver
- 30 working days as an Assistant Supervisor
On top of that, the standard training route calls for 625 hours of formal instruction or a recognized equivalent, built on qualified commercial-diver training and documented Air Diver competence. If you're still accumulating field days or working-dive counts, your realistic 2026 "exam date" is whenever that documentation crosses the threshold - not a date on a calendar. For a full breakdown of every prerequisite, see the detailed ADC-AIR-DIVING-SUPERVISOR Requirements guide.
Key Takeaway
Start logging your field days, working dives, and Assistant Supervisor days now if you haven't already. The exam itself is fast to schedule once you're eligible - the bottleneck is almost always the experience record.
The Application and Verification Process
Once your field days, dives, and Assistant Supervisor time are documented, scheduling the exam involves several administrative steps that take real calendar time in 2026:
- Employer verification of your logged field days and working dives
- Written appointment confirming your role as Assistant Supervisor (or equivalent progression)
- Current first aid/CPR documentation
- Applicable medical-fitness provisions for diving personnel
- Submission of the application, along with the $275 fee
Applications and renewals run through Skill N Depth. Because employer sign-off and paperwork verification aren't instantaneous, plan for administrative lead time before your actual exam sitting - don't assume you can submit paperwork one week and sit the exam the next. Building slack into your 2026 plan for this verification step is one of the most overlooked parts of scheduling.
What Exam Day Actually Looks Like
Because the certification exam is administered online, "exam day" for the Air Diving Supervisor credential is less about travel logistics and more about making sure you're prepared to sit for a focused assessment covering supervisor-level responsibilities. The content is grounded in the International Consensus Standards (edition 6.5, 2025-1), section 3.4, which addresses:
Section 3.4 Focus Areas
Candidates should be ready to apply these areas in scenario-style questions, not just recall definitions.
- Supervisor duties and chain-of-command responsibilities
- Dive planning and pre-dive decision-making
- Job hazard analysis for surface-supplied air operations
- Crew and equipment readiness checks
- Emergency preparation and response protocols
- Records - logging, documentation, and reporting requirements
If you want a topic-by-topic breakdown of how these areas map to exam content, review the exam domains guide. For a sense of how demanding the scenario-based questions can feel in practice, the difficulty guide walks through what candidates commonly find challenging.
Remember: nitrox supervision sits outside this core exam and requires its own separate endorsement - don't expect nitrox-specific content on the standard Air Diving Supervisor exam, and don't schedule that endorsement exam expecting it to cover the same ground.
The Five-Year Renewal Clock
Once you pass and receive your certification card, the clock starts running: certification is valid for five years. That renewal deadline is really the second "exam date" concept that matters for long-term career planning - mark it now so you're not scrambling in year four and a half.
| Milestone | What Happens |
|---|---|
| Initial Eligibility | 200 field days, 50 working dives, 30 days as Assistant Supervisor confirmed |
| Application Submission | Employer verification, first aid/CPR, medical fitness, $275 fee submitted via Skill N Depth |
| Exam Sitting | Online ADCI Air Diving Supervisor Certification Examination |
| Certification Issued | Certification card mailed/issued; five-year validity begins |
| Renewal Window | Application for renewal through Skill N Depth before the five-year mark |
Because renewals also route through Skill N Depth, keeping your contact and employment records current with them makes the renewal process far smoother when that five-year date approaches.
Mapping a Prep Schedule Around Section 3.4
Generic study techniques like spaced repetition only help if they're applied to the right material at the right time. Here's a practical way to sequence your final weeks before sitting the exam, built around the section 3.4 focus areas rather than generic test-prep advice:
Supervisor Duties & Dive Planning
- Review chain-of-command scenarios and pre-dive planning checklists
- Cross-reference with your logged Assistant Supervisor experience
Job Hazard Analysis & Crew Readiness
- Practice identifying hazards in surface-supplied air scenarios
- Review equipment readiness verification steps
Emergency Preparation & Records
- Study emergency response protocols and documentation requirements
- Run through sample scenario questions under timed conditions
Full Review & Application Check
- Confirm all verification paperwork is submitted
- Finalize review using a structured study guide and a condensed cheat sheet
Practicing with realistic scenario questions on our practice test platform before your scheduled sitting can help you get comfortable with the format so exam day itself holds no surprises.
Fee Timing and What $275 Covers
The published fee for the Air Diving Supervisor exam is $275, and it covers both the examination itself and the certification card you receive upon passing. Budgeting for this fee is straightforward, but timing matters: submit it alongside your application once your employer verification and experience documentation are complete, not before. For a full cost breakdown including how this fee fits into the broader path (training hours, first aid/CPR renewal, etc.), see the certification cost guide.
Key Takeaway
Passing the exam does not replace the training and experience requirements - the $275 fee only unlocks the exam and card, not a shortcut around field days, dives, or Assistant Supervisor time.
Common Scheduling Mistakes to Avoid
- Assuming a fixed testing calendar exists. There isn't one - your timeline is driven by eligibility and paperwork, not a published exam window.
- Submitting the application before employer verification is finalized. This creates avoidable delays in processing.
- Letting first aid/CPR certification lapse right before intended application submission.
- Confusing this exam with IMCA or UK ADC supervisor scheduling norms. Those programs run on entirely different timelines and requirements.
- Waiting until the five-year mark to think about renewal instead of tracking it well in advance through Skill N Depth.

FAQ
No published fixed windows exist for this online examination. Your effective "exam date" is whenever you've met the field day, working dive, and Assistant Supervisor requirements and completed the verification paperwork.
It varies based on how quickly your employer completes verification of field days, working dives, first aid/CPR status, and medical-fitness provisions. Build in lead time rather than assuming immediate turnaround.
Passing the exam is one requirement among several. It does not replace the required 200 field days, 50 working dives, 30 days as Assistant Supervisor, or the 625 hours of formal instruction (or recognized equivalent).
Certification is valid for five years. Start reviewing renewal requirements with Skill N Depth well before that five-year mark to avoid a lapse in your certification status.
No. Nitrox supervision requires a separate applicable endorsement and is scheduled and examined independently of the core Air Diving Supervisor certification.
