What Is A/D Director?
A/D Director stands for Assembly/Disassembly Director, a credential issued by the Crane Institute of America (CIA). It identifies the person on a crane crew who is qualified to plan, supervise, and sign off on the assembly and disassembly of telescoping-boom, lattice-boom, and tower cranes. This is not a generic "crane certification" - it is a specific, narrow role defined by OSHA's crane rules, and CIA built a dedicated training-and-experience pathway around it.
If you searched "A/D Director," you likely landed here because your employer, a jobsite requirement, or a career move requires you to hold this specific CIA credential. This site, A/D Director Exam Prep, focuses exclusively on the CIA written examination tied to that credential - not on any other program that happens to share the same acronym. Every fact below comes directly from CIA's published A/D Director materials.
Who Issues It: Certificate of Training vs. Certification
One of the most misunderstood parts of the A/D Director pathway is the difference between two documents that sound similar but are not the same:
- Certificate of Training - awarded when you complete the CIA A/D Director course. It proves you sat through the instruction; it does not, by itself, make you a certified A/D Director.
- A/D Director Certification - the full credential, which requires the training plus documented field experience, physical capability, and a passing score on the written exam.
Confusing the two is a common mistake. For a deeper breakdown of exactly which boxes you need to check, see A/D Director Requirements 2026: Eligibility, Prerequisites & How to Qualify and the companion overview at A/D Director Certification.
| Item | Certificate of Training | A/D Director Certification |
|---|---|---|
| Requires classroom/course completion | Yes | Yes |
| Requires documented field experience | No | Yes - 2+ years mobile/tower crane A/D experience |
| Requires passing a written exam | No | Yes |
| Requires physical capability documentation | No | Yes |
Eligibility Requirements
To pursue full A/D Director certification through CIA, a candidate must satisfy four distinct conditions:
- Complete the CIA A/D Director training course.
- Demonstrate physical capability to perform assembly/disassembly duties.
- Provide documentation of at least two years of mobile- or tower-crane assembly/disassembly experience.
- Pass the written examination.
None of these steps is optional, and skipping the documentation piece is the most common reason applications get delayed. If you're still mapping out whether you currently qualify, the detailed walkthrough at A/D Director Requirements 2026 goes step-by-step through what counts as acceptable experience documentation.
Key Takeaway
Passing the written exam is only one of four requirements. Line up your two years of documented experience and physical-capability confirmation early so the exam isn't your only bottleneck.
The Nine Course Topics
CIA's A/D Director training - and by extension the written exam - is built around nine published topics. These are the concrete, testable subject areas candidates need to master, spanning telescoping-boom, lattice-boom, and tower crane work:
Director Responsibilities & Site-Specific Hazards
Candidates must understand what the A/D Director is personally accountable for on a job site, plus how to identify hazards unique to a specific site layout before work begins.
- Scope of the director's authority during A/D operations
- Site walk-down and hazard identification process
Power Line Awareness & Boom Configurations
Assembly and disassembly near energized power lines is one of the deadliest failure points in crane work, and boom configuration knowledge is foundational to safe setup.
- Minimum clearance planning near power lines
- Telescoping-boom vs. lattice-boom assembly sequencing
Jibs, Extensions & Post-Assembly Inspection
Erecting and stowing jibs and extensions correctly, then verifying the finished assembly through a structured post-assembly inspection, are both heavily tested skill areas.
- Jib/extension erecting and stowing procedures
- Post-assembly inspection checklist logic
Assist Cranes, Fall Protection & Rigging Selection
Many A/D jobs require a second "assist" crane, proper fall protection for crew working at height on the boom, and correct rigging selection for the loads involved.
- Coordinating assist-crane operations safely
- Selecting rigging hardware appropriate to the assembly task

The Written Examination
After completing training and while gathering your experience documentation, you'll need to pass CIA's written examination to complete the certification. The exam draws directly from the nine course topics above and from the assigned study materials - it is not a generic crane-safety quiz, so studying material unrelated to A/D-specific procedures wastes time.
Because CIA does not publish granular scoring breakdowns publicly, avoid trusting any source that cites specific pass-rate percentages for this exam unless it's directly sourced from CIA. If you want a grounded, numbers-honest discussion of what's actually known about difficulty and outcomes, read How Hard Is the A/D Director Exam? Complete Difficulty Guide 2026 and A/D Director Pass Rate 2026: What the Data Shows. For the specific score threshold you're aiming for, see A/D Director Passing Score 2026: Exactly What You Need to Pass.
Official Study Materials
CIA points candidates toward a specific, limited set of resources rather than a broad reading list. Stick to these and you're studying what's actually testable:
- Mobile Cranes Handbook
- Rigging Handbook
- A/D Director workbook (the course-specific manual)
- OSHA 1926 Subpart CC - the regulatory backbone behind nearly every scenario question you'll see
Pair these official sources with practice questions modeled on the nine course topics - you can start with the free practice tools on the main A/D Director practice test site - and a structured guide like A/D Director Study Guide 2026: How to Pass on Your First Attempt.
Recertification and Renewal
A/D Director certification isn't a one-time achievement - CIA lists it among its online recertification options, and the credential must be renewed periodically. Here's what's published:
- Renewal (online or instructor-led) costs $495.
- A renewed certification card is valid for three years.
- The online renewal exercise gives you 10 days after starting it, and most candidates spend roughly 4-5 hours completing it.
These renewal mechanics are separate from the cost of the initial certification pathway. If you're budgeting for the whole process - training, initial exam, and future renewals - the full cost breakdown at A/D Director Certification Cost 2026: Complete Pricing Breakdown lays out every line item.
Key Takeaway
Mark your renewal window early. A $495 renewal with a three-year validity period means the cost of staying current is predictable - but only if you don't let the card lapse.
Who Hires A/D Directors
Crews performing tower crane erections, telescoping-boom mobile crane setups on infrastructure and commercial builds, and lattice-boom assembly for heavy-lift projects all need a qualified A/D Director on site under OSHA 1926 Subpart CC. Typical employers include crane rental companies, heavy-lift and rigging contractors, general contractors running tower crane projects, and specialty erection crews. Holding the certification signals to these employers that you can legally and safely direct A/D operations rather than merely participate in them.

How to Prepare Without Wasting Time
Because the exam maps tightly to the nine course topics, the most efficient prep sequence follows that structure rather than a generic study calendar. A simple way to organize the weeks leading up to your exam date:
Foundations
- Read director responsibilities and site-specific hazards sections in the A/D Director workbook
- Skim relevant portions of OSHA 1926 Subpart CC
High-Risk Procedures
- Study power-line clearance rules and boom assembly configurations
- Review Mobile Cranes Handbook chapters on telescoping- and lattice-boom setup
Inspection & Rigging
- Drill post-assembly inspection checklists
- Work through Rigging Handbook sections on selection and use
Final Review
- Take timed practice questions covering assist cranes, fall protection, and jib/extension procedures
- Revisit weak topics with a condensed reference like A/D Director Cheat Sheet 2026: One-Page Review of Must-Know Facts
This sequencing works because it front-loads the conceptual, responsibility-based material before moving into hands-on procedural topics, ending with the highest-consequence items (fall protection, assist cranes) right before exam day. Run through timed practice sets on the practice test platform throughout, not just in the final week - spacing your exposure to each topic reduces the chance you freeze on a scenario question during the real exam.
