ADC-AIR-DIVER Pass Rate 2026: What the Data Shows

Why "Pass Rate" Means Something Different for Air Diver

If you've searched for an "ADC-AIR-DIVER pass rate," you've probably noticed something odd: there isn't a published percentage anywhere. That's because Air Diver, as defined by the Association of Diving Contractors International (ADCI) in its International Consensus Standards, is a training- and experience-based proficiency classification - not a standalone graded written examination administered on a set date with a scored outcome. There's no national testing center handing out pass/fail letters the way there is for some other trades.

That doesn't mean there's nothing to prepare for. Candidates still need to demonstrate occupational knowledge, meet documented experience thresholds, and satisfy medical and safety-training requirements before a contractor or training program will sign off on the Air Diver designation. The "test" candidates actually face is a combination of logged field performance, supervisor sign-off, and knowledge checks tied to the Consensus Standards - which is exactly why practice questions modeled on those standards are useful preparation, even without an official numeric pass rate to chase.

How Air Diver Qualification Actually Works

Air Diver sits inside ADCI's Surface-Supplied Air Diver classification. To reach that designation, a candidate's file needs to show:

• At least 625 documented hours of commercial-diver instruction meeting ANSI/ACDE-01-2015 or a recognized equivalent training standard.
• A minimum of 100 field days in commercial diving operations.
• At least 30 working dives logged specifically as an Air Diver - and only surface-supplied dives count toward this total; recreational scuba time does not apply.
• Qualifying dives completed within the 24 months immediately preceding designation, so experience has to be recent, not just cumulative.
• Current first aid/CPR certification and applicable medical fitness clearance.

Recreational scuba certification alone will not satisfy any part of this pathway - a point worth repeating because it's a common misconception among people exploring commercial diving for the first time. For a full breakdown of every prerequisite and how the pieces fit together, see the ADC-AIR-DIVER Requirements guide, which walks through documentation order and common eligibility mistakes in more depth.

The Knowledge Review Candidates Must Master

Even though Air Diver isn't a single scored written exam, ADCI's Consensus Standards define the occupational knowledge base examiners and training programs use to evaluate readiness. That review is grounded in International Consensus Standards, edition 6.5, 2025-1, section 3.3. This is the section that spells out the practical, safety-critical knowledge a Surface-Supplied Air Diver is expected to hold before being signed off - covering surface-supplied equipment operation, communication procedures, decompression awareness, and job-site safety protocols relevant to air diving specifically.

Because this material is standards-based rather than trivia-based, the most effective preparation looks like structured knowledge checks against the actual standard text, not generic dive-shop quizzes. If you want a section-by-section walkthrough of what's covered, the ADC-AIR-DIVER Exam Domains guide breaks the content areas down further, and the ADC-AIR-DIVER Cheat Sheet condenses the must-know terms and procedures into a one-page reference for quick review before a check-off.

Who Hires Air Divers, and Why Preparation Still Matters

Surface-supplied Air Diver is typically the entry point into commercial diving careers - inland construction, harbor and port work, offshore support, and inspection/maintenance contracts often look for divers holding this classification as a baseline qualification before advancing to mixed-gas or other specialty designations. Because contractors are hiring based on a combination of your logged experience and your demonstrated knowledge of surface-supplied procedures, being genuinely fluent in the standards - not just technically eligible on paper - affects how competitive your application looks.

This is also why "pass rate" framing can be misleading for job seekers: a hiring supervisor isn't evaluating a test score, they're evaluating whether your file and your working knowledge line up. For more on how this classification translates into actual job opportunities and what employers scan for, see ADC-AIR-DIVER Jobs.

Where Candidates Typically Fall Short

Without a published failure-rate statistic to point to, it's more useful to look at the qualitative patterns that repeatedly trip candidates up during the qualification process:

• Incomplete dive logs. Missing detail on whether a dive was surface-supplied, or missing dates that place it outside the 24-month window, are common documentation gaps.
• Confusing recreational and commercial hours. Recreational scuba time, no matter how extensive, does not count toward the 625 training hours or the 30 required dives.
• Underestimating the knowledge review. Candidates who focus only on accumulating field days sometimes under-prepare for the standards-based knowledge component tied to section 3.3.
• Letting first aid/CPR or medical fitness lapse. These supporting credentials are easy to overlook while focused on hours and dives, but they're essential to the file being considered complete.

If you're trying to gauge how demanding this process feels in practice compared to other commercial diving pathways, the How Hard Is the ADC-AIR-DIVER Exam guide covers difficulty expectations in more detail, and ADC-AIR-DIVER Passing Score explains what "meeting standard" looks like for the knowledge review component.

Building a Realistic Preparation Timeline

Because Air Diver qualification blends supervised field time with a knowledge review, your preparation plan should run on two parallel tracks: logging verified field days/dives, and working through standards-based knowledge checks tied to section 3.3. A simple phased approach works well for most candidates approaching their designation window.

Cost, Renewal, and Documentation Mechanics

The published Air Diver card fee is $175. Certification is valid for five years, and both new applications and renewals are processed through Skill N Depth. Because renewal isn't automatic, candidates should plan ahead for what documentation will need to be current again at the five-year mark - first aid/CPR, medical fitness, and any updated dive experience if required.

For a complete look at every fee, renewal cost, and budgeting consideration tied to this classification, see the ADC-AIR-DIVER Certification Cost breakdown. And if you're still weighing whether pursuing this classification fits your career plans, Is the ADC-AIR-DIVER Certification Worth It? lays out the return-on-investment considerations in more depth.

If you want to practice standards-based knowledge questions modeled on section 3.3 while you're logging field time, you can work through structured drills on the main practice test platform to keep the occupational-knowledge side of your preparation moving alongside your dive log. Many candidates use practice question sets as a low-stakes way to confirm they understand surface-supplied procedures before facing a real check-off.
