- Air Diver has no single numeric "passing score" - it's a documented-hours and dive-count qualification.
- You need at least 625 hours of ANSI/ACDE-01-2015-aligned training plus 100 field days and 30 working dives.
- Qualifying dives must be surface-supplied and completed within the 24 months before designation.
- Occupational knowledge is reviewed against International Consensus Standards edition 6.5, 2025-1, section 3.3.
Why "Passing Score" Is the Wrong Question for Air Diver
If you're searching for a percentage - 70%, 75%, 80% - that will tell you whether you "passed" the ADCI Air Diver credential, you're applying the wrong mental model. Air Diver, administered under the Association of Diving Contractors International's (ADCI) International Consensus Standards, is the Surface-Supplied Air Diver classification. It is a training- and experience-based proficiency credential, not a standalone written examination with a scaled cutoff score.
That distinction matters because a lot of generic exam-prep content treats every "ADC-AIR-DIVER" search the same way, importing pass-rate numbers and scoring rubrics from unrelated certifications that happen to share letters in their name. None of that applies here. There is no ADCI Air Diver exam blueprint that reports a numeric passing threshold. Instead, qualification is demonstrated through documented training hours, field days, working dives, and an occupational knowledge review tied to the published standards.
For a broader orientation to how the credential is structured before you dig into the numbers here, our ADC-AIR-DIVER Requirements guide and the What Is ADC-AIR-DIVER? overview are good starting points.
What Actually Qualifies You as an Air Diver
Instead of a passing score, ADCI's consensus standards define qualification through a combination of training and logged field experience. To be designated as an Air Diver under the standard route, you need:
Minimum Training Hours
At least 625 documented hours of commercial-diver instruction that meets ANSI/ACDE-01-2015 or a recognized equivalent standard. This is program-level training, not self-study - it's delivered through a commercial diving school and logged formally.
- Training must be documented, not merely attested to informally
- Equivalent programs must map to the ANSI/ACDE-01-2015 framework
Field Days and Working Dives
Beyond classroom and pool-based training, candidates must accumulate at least 100 field days and 30 working dives as an Air Diver. Only surface-supplied dives count toward this total - recreational scuba time, no matter how extensive, does not satisfy the requirement.
- Recreational scuba certification alone does not qualify an applicant
- Dives must be logged with enough detail to verify surface-supplied method
The 24-Month Recency Window
Required qualifying dives must fall within the 24 months preceding designation. This recency rule exists so that the credential reflects current operational competence, not experience from years earlier that may no longer reflect field conditions or equipment practices.
- Older dive logs outside the 24-month window don't count toward the working-dive minimum
- Candidates re-entering the field after a gap may need to log fresh qualifying dives
These three pillars - hours, field days/dives, and recency - function as the real "passing" bar for Air Diver. For a deeper breakdown of how each of these prerequisites fits together, see our full ADC-AIR-DIVER Requirements 2026 guide.
The Knowledge Review Standard: ICS 6.5, Section 3.3
Alongside logged hours and dives, candidates are expected to demonstrate occupational knowledge. ADCI's occupational knowledge review draws from the International Consensus Standards, edition 6.5, 2025-1, section 3.3. This is the reference point that governs what an Air Diver is expected to know and understand about surface-supplied air diving operations.
Because there's no separate published domain-weighting breakdown for a standalone Air Diver exam, your best strategy is to work directly from the standard rather than guessing at a scoring rubric that doesn't exist. If you want a structured walkthrough of how the content in the standards maps to real-world knowledge checks, our ADC-AIR-DIVER Exam Domains 2026 guide organizes the material into study-friendly sections.
Key Takeaway
Treat section 3.3 of the International Consensus Standards as your primary study text - not a third-party guess at what "should" be tested. Everything else, including practice questions, should be built to reinforce that source material.
Documentation That Proves You Qualify
Because Air Diver qualification is document-driven rather than score-driven, the paperwork itself functions as your "proof of passing." Supporting records that examiners and employers expect to see include:
- Formal training records showing the 625+ hours and the instructional program that delivered them
- Dive logs itemizing field days and working dives, clearly identifying surface-supplied method and dates
- Current first aid/CPR certification
- Documentation of applicable medical fitness for diving
Gaps or inconsistencies in this documentation are far more likely to derail a candidate than any single knowledge question. If your dive log doesn't clearly distinguish surface-supplied dives from other types, or if your training hours aren't itemized against ANSI/ACDE-01-2015, that's where qualification stalls - not on a missed exam score.
Fees, Cards, and the Skill N Depth Process
The published card fee for Air Diver is $175. Both new applications and renewals are processed through Skill N Depth, the platform ADCI uses to manage credential issuance. Certification, once granted, is valid for five years, after which renewal - again through Skill N Depth - is required to maintain active status.
| Item | Detail |
|---|---|
| Card fee | $175 |
| Minimum training hours | 625+ hours (ANSI/ACDE-01-2015 or equivalent) |
| Minimum field days | 100 |
| Minimum working dives | 30 (surface-supplied only) |
| Qualifying dive window | Within 24 months of designation |
| Validity period | 5 years |
| Application/renewal platform | Skill N Depth |
For a full walkthrough of every cost element beyond the card fee - training program costs, medical exams, and renewal logistics - see the ADC-AIR-DIVER Certification Cost 2026 breakdown. If you're weighing timing around Skill N Depth submission windows, the ADC-AIR-DIVER Exam Dates 2026 guide covers scheduling considerations.
How to Prepare for the Occupational Knowledge Review
Even though Air Diver isn't a scored written exam in the traditional sense, candidates still benefit from structured knowledge checks against section 3.3 of the standards before stepping into field evaluations or employer screening. A focused review schedule can help you internalize the standard's language rather than skimming it once and hoping it sticks.
Standards Familiarization
- Read through International Consensus Standards section 3.3 in full
- Cross-reference terminology with your training program materials
Documentation Audit
- Verify your 625+ training hours are itemized and complete
- Confirm dive logs clearly show surface-supplied method, dates, and field-day counts
Applied Knowledge Checks
- Work through standards-based practice questions covering surface-supplied air diving procedures
- Identify weak areas and re-read the corresponding standard sections
Practice questions built around section 3.3 are best used as original standards-based knowledge checks and application preparation - they reinforce what you already learned in commercial-diver training and supervised field experience, not a replacement for either. Our ADC-AIR-DIVER Study Guide 2026 lays out a fuller preparation sequence, and you can start practicing directly on our practice test platform to see how knowledge-check questions are structured around the standard.

Common Reasons Candidates Fall Short
Since there's no single score to miss by a point or two, "failing" to qualify for Air Diver usually looks different than failing a traditional exam. The most common shortfalls are:
- Insufficient documented hours: Training that doesn't clearly map to ANSI/ACDE-01-2015 or an equivalent, leaving gaps in the 625-hour requirement.
- Dive count shortfalls: Logging dives that weren't surface-supplied, or that fall outside the 24-month recency window, and therefore don't count toward the 30-dive minimum.
- Assuming recreational certification transfers: Recreational scuba experience, regardless of hours logged, does not substitute for commercial surface-supplied dive time.
- Missing supporting paperwork: Lapsed first aid/CPR certification or incomplete medical fitness documentation at the time of application.
- Weak grasp of section 3.3 concepts: Treating the occupational knowledge review as an afterthought rather than studying the standard directly.
Understanding these failure points ahead of time is far more useful than chasing a percentage that doesn't exist for this credential. For context on how employers view the credential once you've qualified, see ADC-AIR-DIVER Jobs and Is the ADC-AIR-DIVER Certification Worth It?
Frequently Asked Questions
No. Air Diver is a training- and experience-based proficiency credential, not a scored standalone written exam. Qualification is demonstrated through documented training hours, field days, working dives, and an occupational knowledge review against the International Consensus Standards.
At least 625 documented hours of commercial-diver instruction meeting ANSI/ACDE-01-2015 or a recognized equivalent standard.
No. Only surface-supplied dives count toward the 30 working-dive minimum, and recreational scuba certification alone does not qualify an applicant.
Dives outside the 24-month window preceding designation do not count toward the required 30 working dives, so candidates may need to log fresh surface-supplied dive time.
It's based on the International Consensus Standards, edition 6.5, 2025-1, section 3.3, which candidates should study directly rather than relying on generic exam-prep assumptions.
