What the ADCI Air Diving Supervisor Credential Actually Requires
The Association of Diving Contractors International (ADCI) classifies this credential as Air Diving Supervisor, formally described in the standards as Surface-Supplied Air Diving Supervisor. That naming matters because it draws a hard line between this qualification and other supervisor schemes that share similar-sounding acronyms. If you're researching this cert, keep your ADCI preparation distinct from IMCA and UK ADC supervisor schemes - the eligibility paths, governing documents, and application processes do not overlap.
Before diving into the numbers, it helps to understand the shape of the pathway: this is not a stand-alone exam you can sit after a weekend course. It's a capstone credential that sits on top of years of documented field work as a commercial diver. If you haven't yet reviewed the basics of what this role covers, What Is ADC-AIR-DIVING-SUPERVISOR? and ADC-AIR-DIVING-SUPERVISOR Meaning are useful starting points before you commit time to the eligibility checklist below.
Prerequisites: Field Days, Working Dives, and Assistant Supervisor Time
ADCI's eligibility requirements are experience-heavy by design. To qualify for the Air Diving Supervisor certification, a candidate must document:
- At least 200 field days as an Air Diver - accumulated time actually working commercial air diving operations, not just training days.
- 50 working dives as an Air Diver - actual in-water working dives under surface-supplied air conditions.
- 30 working days as an Assistant Supervisor - time spent supporting a qualified supervisor on live jobs, which is where most candidates first get exposure to dive planning, job hazard analysis, and crew coordination.
These three thresholds work together, not independently. A diver with plenty of field days but no assistant-supervisor time isn't eligible yet, and vice versa. Employers and dive companies typically track these numbers through dive logs, job records, and payroll documentation, which is why accurate daily logging from day one in the field pays off later.
Why the Assistant Supervisor Requirement Exists
The 30 working days as Assistant Supervisor exist because supervising is a different skill set than diving. Candidates need direct exposure to the supervisory decision-making covered later by the standards - crew readiness checks, communications discipline, and emergency response calls - before they're expected to hold that role independently.
- Time logged must be verifiable by an employer, not self-reported informally
- Assistant Supervisor days typically overlap with active job sites, not classroom settings
- This experience feeds directly into the judgment tested by the certification exam
Training Pathway and the 625-Hour Standard
Qualification for the Air Diving Supervisor certification builds on top of qualified commercial-diver training plus documented Air Diver competence. The standard training route associated with this pathway includes 625 hours of formal instruction, or a recognized equivalent for candidates who came up through alternative but comparable programs.
This is a meaningful distinction from purely experience-based pathways: ADCI expects candidates to have gone through structured, formal commercial diving instruction before the field-day and working-dive clock even starts counting toward supervisor eligibility. If your training history is non-traditional, confirm equivalency documentation early, since it affects when you can realistically submit your application.
Key Takeaway
Don't wait until you've hit 200 field days to check whether your original training program satisfies the 625-hour equivalent. Verify this early so it doesn't become a bottleneck right before you apply.
Exam Mechanics, Fee, and Application Paperwork
Once the experience and training thresholds are met, candidates sit an online ADCI Air Diving Supervisor Certification Examination. The published fee is $275, and that amount covers both the examination itself and the certification card issued upon passing.
A critical point that trips up under-prepared applicants: passing the examination does not replace the training and experience requirements. The exam confirms knowledge of supervisory duties and standards content, but ADCI still requires the full documentation trail - field days, working dives, Assistant Supervisor time, employer verification - regardless of exam performance. Think of the exam as one gate among several, not the only gate.

If you want a sense of how the exam itself is structured and what to expect on test day, How Hard Is the ADC-AIR-DIVING-SUPERVISOR Exam? Complete Difficulty Guide 2026 walks through that separately from the eligibility rules covered here.
| Requirement | Minimum Threshold |
|---|---|
| Field days as Air Diver | 200 days |
| Working dives as Air Diver | 50 dives |
| Working days as Assistant Supervisor | 30 days |
| Standard formal training | 625 hours (or recognized equivalent) |
| Exam + certification card fee | $275 |
| Certification validity | 5 years |
Standards Scope: What Section 3.4 Covers
The examination and the on-the-job expectations both trace back to the International Consensus Standards, edition 6.5, 2025-1, specifically section 3.4, which addresses supervisor duties. Candidates should be comfortable with the material across these areas:
Dive Planning
Understanding how a supervisor structures a dive plan before crew and equipment ever reach the water, including sequencing of tasks and depth/duration considerations relevant to surface-supplied air operations.
Job Hazard Analysis
Identifying site-specific hazards before work begins and documenting mitigation steps - a core supervisory responsibility rather than a diver-level task.
Crew and Equipment Readiness
Confirming that personnel are qualified for the assigned roles and that surface-supplied air equipment has been checked and is fit for the job at hand.
Emergency Preparation
Knowing what a supervisor must have in place before a dive starts - contingency plans, communication protocols, and readiness to respond if something goes wrong underwater.
Records
Maintaining the documentation trail that supports both the job itself and the supervisor's own ongoing qualification history.
One important scope note: nitrox supervision is not automatically included. It requires the applicable separate endorsement beyond the base Air Diving Supervisor certification. If your work involves nitrox operations, don't assume this credential alone covers you - check the separate endorsement path before you're assigned to a job that requires it.
For a deeper walkthrough of how these areas connect and where candidates most often underestimate the depth of section 3.4, see ADC-AIR-DIVING-SUPERVISOR Exam Domains 2026: Complete Guide to All 0 Content Areas.
Supporting Documentation and Medical/First Aid Provisions
Beyond the raw day counts, ADCI's qualification process leans on several supporting pieces that candidates sometimes overlook until the application stage:
- Employer verification - someone in a position of authority confirms your field days, working dives, and Assistant Supervisor time actually occurred as logged.
- Experience records - your own dive logs and job records need to be complete and consistent with what employers verify.
- Written appointment - documentation showing you were formally appointed to supervisory duties, not just informally filling in.
- Current first aid/CPR - an active certification, not an expired one, at the time of application.
- Applicable medical-fitness provisions - confirming you meet the medical standards tied to commercial diving work.
Gathering these pieces takes time, and it's common for candidates to have the field days and dives covered long before their paperwork trail is application-ready. Start requesting employer verification letters and confirming your first aid/CPR expiration dates well before you plan to submit.
Certification Validity and Renewal Through Skill N Depth
Once earned, the Air Diving Supervisor certification is valid for five years. Applications and renewals are handled through Skill N Depth, so it's worth understanding that process ahead of your certification's expiration rather than scrambling at the five-year mark. Because the credential ties directly to active supervisory work, staying current also means keeping your first aid/CPR and any applicable medical-fitness documentation up to date across that same window.

Mapping the Requirements to a Prep Timeline
Because eligibility here is dominated by accumulated field experience rather than a short study sprint, your "study timeline" really has two phases: the multi-year experience-building phase, and a focused review phase once you're eligible to sit the exam. The second phase is where most candidates benefit from structured study techniques.
