- Air Diver is ADCI's Surface-Supplied Air Diver classification, built on documented training and fieldwork, not a standalone written exam.
- You need at least 625 documented commercial-diver training hours meeting ANSI/ACDE-01-2015 or a recognized equivalent.
- Qualification requires 100 field days and 30 working dives as an Air Diver, with required dives completed in the preceding 24 months.
- Only surface-supplied dives count toward the 30 working dives - recreational scuba time does not qualify you.
What the Air Diver Classification Actually Is
Before diving into requirements, it's worth being precise about what Air Diver is - because confusion here causes candidates to prepare for the wrong thing entirely. Air Diver is the Surface-Supplied Air Diver classification recognized by the Association of Diving Contractors International (ADCI) under its International Consensus Standards. It is a training- and experience-based proficiency credential. There is no separate ADCI "Air Diver written exam" that stands apart from your training and logged fieldwork - the classification is earned by combining documented instruction hours with a minimum amount of verified working-dive experience.
That distinction matters for how you prepare. If you're looking for a multiple-choice test date to circle on a calendar, you're looking at the wrong process. Instead, your path runs through an accredited training program, a logbook, and a knowledge review tied to the standards themselves. For a broader orientation on the credential before you get into the mechanics, see What Is ADC-AIR-DIVER? and ADC-AIR-DIVER Meaning.
Core Eligibility Requirements
Air Diver eligibility rests on a small number of hard requirements. Meeting the letter of each one - not just the spirit - is what gets an application approved without back-and-forth.
Training Hours
Applicants need at least 625 documented hours of commercial-diver instruction that satisfies ANSI/ACDE-01-2015 or a recognized equivalent standard. This training is typically completed at an accredited commercial diving school before a candidate ever enters the field-day and working-dive phase.
- Instruction must be documented, not self-reported
- Programs should map to ANSI/ACDE-01-2015 competencies
- Equivalent programs must be verifiable against the same standard
Medical and Safety Prerequisites
Beyond training hours, candidates need current first aid/CPR certification and applicable medical fitness clearance appropriate to commercial diving work. These aren't optional add-ons - they're baseline conditions for being considered field-ready.
- First aid/CPR must be current, not expired, at time of application
- Medical fitness documentation should be on file and up to date
Key Takeaway
Line up your training hours, first aid/CPR, and medical fitness paperwork before you start counting field days - gaps discovered late slow down the entire qualification timeline.
Field Days, Working Dives, and the 24-Month Window
This is the section candidates most often underestimate. Air Diver qualification requires at least 100 field days and at least 30 working dives performed as an Air Diver. Two rules govern how these count:
- Only surface-supplied dives count. Scuba dives, recreational dives, or any dive mode outside surface-supplied air do not apply toward the 30 working dives.
- Timing matters. The required qualifying dives must fall within the 24 months preceding designation. Experience from years earlier, without recent qualifying dives, will not satisfy the requirement on its own.
In practice, this means a candidate can't simply accumulate a large lifetime dive count and stop paying attention to recency. The 24-month lookback keeps the classification tied to current, active field capability rather than historical experience alone.
Documentation You Must Compile
Every piece of the eligibility puzzle needs a paper trail. Supervisors, training providers, and dive logs all feed into the application package. At minimum, plan to assemble:
- Training completion records showing the 625+ hours and the standard they satisfy
- A verified dive log showing field days and working dives, with dive mode (surface-supplied) clearly indicated
- Dates for each qualifying dive, since the 24-month window will be checked against them
- Current first aid/CPR certificate
- Medical fitness documentation
If you want a condensed reference sheet to keep next to your logbook while you assemble this package, the ADC-AIR-DIVER Cheat Sheet lays out the must-know facts in one place.
Fees, Application, and Skill N Depth
The published card fee for Air Diver is $175. New applications and renewals are processed through Skill N Depth, the platform ADCI uses to manage classification records. Certification itself is valid for five years, after which renewal - again through Skill N Depth - is required to maintain active status.
For a full breakdown of what this fee covers and how it fits into the broader cost of pursuing the classification (training, travel, gear, and time away from paid work), see ADC-AIR-DIVER Certification Cost 2026: Complete Pricing Breakdown.
| Requirement | Minimum / Detail |
|---|---|
| Training hours | 625+ hours meeting ANSI/ACDE-01-2015 or recognized equivalent |
| Field days | 100 minimum |
| Working dives as Air Diver | 30 minimum, surface-supplied only |
| Qualifying dive window | Within 24 months preceding designation |
| Card fee | $175 |
| Validity period | 5 years |
| Application/renewal platform | Skill N Depth |
Occupational Knowledge Review and Section 3.3
Alongside training and fieldwork, candidates should be prepared for an occupational knowledge review drawn from the International Consensus Standards, edition 6.5, 2025-1, section 3.3. This is where standards-based knowledge checks come in - questions built around the same terminology, procedures, and safety expectations that govern surface-supplied air diving operations in the field.
It's important to frame this correctly: practice questions and knowledge checks are a way to reinforce and test recall of standards content - they are not a substitute for commercial training or supervised field experience. No amount of question drilling replaces the 625 hours of instruction or the 30 logged working dives. What it does is help confirm that terminology, procedures, and standards references are second nature by the time you're applying.
To understand how the underlying content is organized before you start reviewing, check the ADC-AIR-DIVER Exam Domains 2026: Complete Guide to All Content Areas. If you're trying to gauge how demanding the review process feels relative to other steps in qualification, How Hard Is the ADC-AIR-DIVER Exam? Complete Difficulty Guide 2026 walks through that in more detail, and ADC-AIR-DIVER Passing Score 2026: Exactly What You Need to Pass covers what "passing" looks like for the knowledge component.
Key Takeaway
Treat section 3.3 of the International Consensus Standards as your primary reference text - it's the source document behind the occupational knowledge review, not a generic diving manual.
Who Hires Air Divers
Surface-supplied Air Diver qualification is aimed at candidates entering or advancing within commercial diving operations - inland and offshore construction, inspection, and maintenance work where surface-supplied air is the standard mode of diving. Employers in this space generally look for exactly the things the classification verifies: documented training hours against a recognized standard, a real dive log with recent surface-supplied working dives, and current safety credentials.

Preparing for the Knowledge Review Without Skipping Fieldwork
Because Air Diver qualification is anchored in hours and dives you can't compress, your preparation timeline should follow your fieldwork schedule rather than a fixed study calendar. A practical approach:
Training and Documentation
- Confirm your training program maps to ANSI/ACDE-01-2015
- Start a dive log template that separates surface-supplied dives from any other mode
Accumulate Field Days and Dives
- Track progress toward 100 field days and 30 working dives
- Note dates carefully - only dives within the 24-month window before designation will count
Standards Review
- Work through section 3.3 of the International Consensus Standards
- Use standards-based practice questions to check recall, not to replace training
Application and Submission
- Compile training records, dive log, first aid/CPR, and medical fitness documents
- Submit through Skill N Depth with the $175 card fee

Common Reasons Applications Get Delayed
Most Air Diver applications that stall do so for a handful of predictable reasons:
- Non-surface-supplied dives counted by mistake. Recreational or non-surface-supplied working dives don't count toward the 30 required dives.
- Stale dive dates. Dives logged outside the 24-month window preceding designation won't satisfy the recency requirement, even if the total dive count looks sufficient.
- Incomplete training documentation. Training hours that can't be tied clearly to ANSI/ACDE-01-2015 or an equivalent create verification delays.
- Expired first aid/CPR at submission. This is an easy fix, but easy to overlook when everything else is in order.
Running through the official reference material before submitting is worth the time.

FAQ
No. Air Diver is a training- and experience-based classification. There is an occupational knowledge review tied to the International Consensus Standards, but it sits alongside documented training hours and logged fieldwork rather than replacing them.
No. Only surface-supplied dives count toward the 30 required working dives. Recreational scuba certification alone does not qualify an applicant for Air Diver status.
The required qualifying dives must fall within the 24 months preceding designation. Older dives can support your overall experience narrative but won't substitute for recent surface-supplied working dives.
The published card fee is $175. Applications and renewals are processed through Skill N Depth, and full certification is valid for five years before renewal is required.
Your commercial-diver instruction should total at least 625 documented hours and meet ANSI/ACDE-01-2015 or a recognized equivalent standard, verifiable through your training provider's records.
