What Is an Air Diving Supervisor?
An Air Diving Supervisor is a commercial diving credential issued by the Association of Diving Contractors International (ADCI). In ADCI's own standards language, the role is described more formally as a Surface-Supplied Air Diving Supervisor - a person qualified to plan, direct, and take responsibility for surface-supplied air diving operations on a job site. This is not a recreational or scuba-instruction title; it sits inside the commercial diving industry's chain of command, above the Air Diver and Assistant Supervisor roles that feed into it.
If you're new to the credential landscape and want the short version, our companion piece What Is ADC-AIR-DIVING-SUPERVISOR? covers the same ground from a slightly different angle, and ADC-AIR-DIVING-SUPERVISOR Meaning breaks down the terminology itself.
Who Certifies It: ADCI and the Consensus Standards
The Association of Diving Contractors International is the certifying body, and it governs the role through its International Consensus Standards. The version currently referenced for supervisor duties is edition 6.5, 2025-1, with section 3.4 specifically addressing supervisory responsibilities: dive planning, job hazard analysis, crew and equipment readiness, emergency preparation, and recordkeeping.
ADCI publishes its supporting documentation and exam application forms directly, including the standards PDF and the supervisor/nitrox exam application. Anyone verifying eligibility or exam mechanics should treat those official ADCI pages as the primary source, and treat any third-party summary - including this one - as a starting point rather than a substitute.
The Qualification Pathway Before You Ever Sit the Exam
Unlike credentials where the exam is the entire gate, ADCI's Air Diving Supervisor certification is built on a documented experience ladder. Before you're eligible to test, you need to have already accumulated:
- At least 200 field days working as an Air Diver
- At least 50 working dives logged as an Air Diver
- At least 30 working days served as an Assistant Supervisor
This experience sits on top of qualified commercial-diver training in the first place. The standard training route into the diving profession itself includes 625 hours of formal instruction, or a recognized equivalent, before a diver even begins accumulating the field days and dives that lead toward supervisor eligibility.
Supporting documentation matters as much as the raw numbers. Employer verification, experience records, a written appointment to supervisory duties, current first aid/CPR certification, and applicable medical-fitness provisions all support the qualification package. For a full breakdown of exactly what paperwork and prerequisites are expected, see ADC-AIR-DIVING-SUPERVISOR Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Key Takeaway
Don't assume the exam is the hard part. The 200 field days, 50 dives, and 30 supervisory days are the real gate - budget your career timeline around accumulating documented experience, not just study hours.
The Certification Exam Itself
Once the experience thresholds and documentation are in place, candidates sit an online ADCI Air Diving Supervisor Certification Examination. The published fee is $275, which covers both the examination and the certification card issued upon passing.
A critical point that catches candidates off guard: passing the exam does not replace the training and experience requirements. The exam confirms knowledge of supervisory duties and standards; it does not substitute for the field days, dives, or assistant-supervisor time. Both tracks - documented experience and exam performance - have to be satisfied independently.

What Section 3.4 Actually Requires of a Supervisor
The heart of what an Air Diving Supervisor is expected to know - and what the exam draws on - is section 3.4 of the International Consensus Standards. That section frames the supervisor's job around five practical clusters:
Dive Planning
Supervisors are responsible for translating a job scope into an actionable dive plan: depths, bottom time, decompression considerations, and contingency options before anyone enters the water.
- Matching the plan to the actual site conditions, not a generic template
Job Hazard Analysis
Before operations begin, the supervisor must identify and document site-specific hazards - currents, vessel traffic, contamination, entanglement risks - and how the crew will mitigate them.
- JHA documentation is part of the supervisor's accountability trail
Crew and Equipment Readiness
This covers verifying that divers, tenders, and support staff are qualified and fit for the assignment, and that surface-supplied air equipment is inspected, tested, and ready.
- Readiness checks are the supervisor's direct responsibility, not delegated away
Emergency Preparation
Supervisors must have emergency procedures in place before diving starts - evacuation, recompression access, and communication protocols - rather than improvising if something goes wrong.
- Preparation is evaluated as a proactive duty, not a reactive skill
Records
Accurate logs of dives, personnel, equipment checks, and incidents are part of the supervisor's ongoing responsibility, tying back to the same documentation habits that support certification renewal.
- Recordkeeping discipline is a recurring theme across every other duty area

Fees, Validity, and Renewal Through Skill N Depth
Certification is valid for five years from issuance. Applications and renewals are processed through Skill N Depth, ADCI's administration partner, rather than directly through a self-service ADCI portal. This means keeping your documentation - experience records, medical fitness paperwork, and current first aid/CPR - organized well before the five-year mark, since renewal isn't automatic.
| Requirement | Detail |
|---|---|
| Exam fee | $275 (includes exam and certification card) |
| Field days as Air Diver | 200 minimum |
| Working dives as Air Diver | 50 minimum |
| Days as Assistant Supervisor | 30 minimum |
| Formal training hours | 625 hours (or recognized equivalent) |
| Certification validity | 5 years |
| Renewal administered by | Skill N Depth |
Nitrox Endorsement and Avoiding Scheme Confusion
Base certification as an Air Diving Supervisor covers surface-supplied air operations. If your work involves nitrox, that's not automatically included - nitrox supervision requires the applicable separate endorsement, applied for independently of the base air-diving credential.
It's also worth being deliberate about which supervisor scheme you're studying for. ADCI's Air Diving Supervisor program is distinct from IMCA supervisor schemes and from UK ADC supervisor programs, even though the acronyms and general subject matter overlap heavily. Mixing study materials from those other schemes into ADCI exam prep is one of the more common - and avoidable - mistakes candidates make.
Who Hires an Air Diving Supervisor
Air Diving Supervisors are typically employed by commercial diving contractors working in offshore construction, inspection, salvage, and marine civil works where surface-supplied air diving is the operational method. Employers verify the field days, dive counts, and assistant-supervisor time as part of hiring and internal advancement, which is why documentation discipline matters as much during your diving career as it does at exam time.

Preparing Around the Domains, Not Generic Advice
Because the exam draws directly from section 3.4's five duty clusters, the most efficient prep sequences study time around those clusters rather than around generic test-taking tricks. A reasonable approach: spend early study time reinforcing dive planning and JHA concepts (since these are foundational to every other duty), then move into crew/equipment readiness and emergency preparation once the planning logic is solid, and finish with records - tying the paperwork habits back to what you already do in the field as an Assistant Supervisor.
This is where light use of standard techniques - short timed review blocks, self-testing on standards language rather than passive rereading - pays off, but only when it's anchored to these specific duty areas rather than applied as a one-size-fits-all study plan. Our ADC-AIR-DIVING-SUPERVISOR Study Guide 2026: How to Pass on Your First Attempt lays out a week-by-week sequence built around exactly this structure.
