- CICC does not publish a verified CMRS/LD pass rate, so any specific percentage you see online deserves skepticism.
- The passing score is a scaled 500 on a 200-800 scale, not a raw percentage of correct answers.
- Only 80 of the 100 questions are scored; 20 are experimental and unscored, and you cannot tell which.
- Application is the largest subdimension at 30 scored items, so it deserves the most study time.
Why a Published Pass Rate Is Hard to Find
If you searched for the CMRS/LD pass rate hoping for a clean number, here is the honest answer: the Carpenters International Certification Council (CICC) does not post a verified, citable pass rate for the Certified Master Rigger and Signaler/Lift Director examination. Any site quoting a precise percentage without naming a primary source is guessing, or worse, borrowing a figure from a different credential that happens to share the same acronym.
That last risk is real. Several unrelated certifications abbreviate to "CMRS/LD," and their statistics, fees, and exam formats do not apply here. The credential discussed on this page is the one administered by CICC for members of the United Brotherhood of Carpenters (UBC), delivered through Pearson VUE with CPS HR Consulting coordinating administration. It is separate from NCCCO Lift Director certification and from New York City Master Rigger licensing, and nothing about those programs should be assumed to describe this exam.
So what can you actually learn from "the data"? Quite a lot, as it turns out. The structure of the exam, the scoring method, the blueprint weights, and the makeup of the candidate pool all tell you more about your realistic chances than a single headline percentage ever could. The rest of this article works through those verifiable pieces. For a broader take on difficulty, see our complete difficulty guide for the CMRS/LD exam.
What the 500 Scaled Score Really Means
The passing standard for the CMRS/LD is a scaled score of 500 on a 200-800 scale. This is the single most misunderstood detail among first-time candidates, because it looks like a percentage but is not one.
Scaled versus raw scoring
A scaled score is a mathematical conversion of your raw performance onto a common reporting scale. Different versions of an exam can vary slightly in difficulty, and scaling keeps the passing standard equivalent across forms. In practice, this means:
- 500 does not equal 50%. The midpoint of the scale is not the same thing as half the questions answered correctly.
- You cannot reverse-engineer a required number of correct answers from the scaled cut score alone, and CICC does not publish a raw-score conversion.
- Two candidates with the same number of correct answers could, in principle, see slightly different scaled results if they sat different exam forms.
The practical takeaway is to stop asking "how many can I miss?" and start asking "which blueprint areas am I weakest in?" We cover the scoring mechanics in more depth in our guide to the CMRS/LD passing score.
Exam Structure That Shapes Your Odds
Pass rates are partly a function of exam design. The CMRS/LD format has several features that influence how candidates experience it.
| Feature | CMRS/LD Detail | Why It Matters for Passing |
|---|---|---|
| Question count | 100 total | Substantial coverage across both domains |
| Scored items | 80 scored, 20 experimental/unscored | You cannot identify the unscored items, so treat every question seriously |
| Time allowed | Four hours | Generous pacing; rushing is rarely the problem |
| Open or closed book | Closed book | Load charts, hitch rules, and plan elements must live in your memory |
| Practical component | None; written exam only | Hands-on skill must be translated into written-question reasoning |
| Passing standard | Scaled 500 on 200-800 | Not a raw percentage |
| Certification term | Four years, reexamination for renewal | Plan to retest, so durable understanding beats cramming |
The experimental-item factor
Twenty of your 100 questions do not count. That sounds like good news, but it removes any strategy of "writing off" a hard-feeling question as unscored. A question that feels unfamiliar might be experimental, or it might be a scored item in your weakest area. Since you cannot tell, the only rational approach is to give every item a full effort.
No practical exam means reasoning carries the day
Because there is no separate practical test, the written exam must assess field competence on paper. Expect scenario-style thinking: given a load, a configuration, and site conditions, what is the correct hitch, plan element, or safety response? Experienced riggers sometimes underestimate this, assuming that years on the job guarantee a pass. Field fluency and exam fluency overlap, but they are not identical, especially when the question wording requires you to apply a formal standard rather than a crew habit.
Where the 80 Scored Items Come From
CICC's posted blueprint is based on its 2017 practice analysis. It organizes the scored content into two top-level dimensions, which map directly to the two exam domains: Rigging Procedures and Rigging Safety. Within them sit five subdimensions.
| Domain | Subdimension | Scored Items |
|---|---|---|
| Rigging Procedures | Hitch Configuration | 15 |
| Rigging Procedures | Application | 30 |
| Rigging Safety | Critical Hoist/Lift Plans | 16 |
| Rigging Safety | Site Awareness/Personnel Safety | 15 |
| Rigging Safety | Load Stability | 4 |
Those allocations total 45 scored items for Rigging Procedures and 35 for Rigging Safety, accounting for all 80 scored questions. Our complete guide to both CMRS/LD exam domains breaks each area down further.
Application: The Largest Single Block (30 items)
Application is the biggest individual subdimension, worth more than a third of all scored questions. Weakness here is very hard to offset elsewhere.
- Expect questions that ask you to apply rigging principles to realistic lifting situations rather than recite definitions.
- Practice working from a described scenario to the correct decision, not just recognizing terms.
- Because this block sits inside Rigging Procedures, it pairs naturally with hitch knowledge.
Critical Hoist/Lift Plans (16 items)
The second-largest block rewards candidates who understand what makes a lift "critical" and what a plan must address before the load leaves the ground.
- Know the purpose and components of a written lift plan.
- Understand the responsibilities that attach to planning, not just execution.
- Expect questions that test judgment about when a plan is required.
Hitch Configuration (15) and Site Awareness/Personnel Safety (15)
These two blocks are equal in weight and often underprepared because candidates assume field experience covers them.
- Hitch Configuration rewards precise knowledge of how configuration choices affect the load and the rigging.
- Site Awareness/Personnel Safety covers hazards around the lift, including people, surroundings, and communication.
Who Sits for This Exam
A pass rate is only meaningful in light of who is taking the test. The CMRS/LD candidate pool is not a random sample of the public. Eligibility requires UBC membership and a current Certified Rigger and Signaler (CRS) credential or a qualifying rigging qualification. Candidates also begin the process through their Local Training Center rather than registering independently.
That pre-screening has two implications for how you should think about your chances:
- The pool is already experienced. Most candidates have meaningful rigging background, so the exam is calibrated against people who know the work. Being "good in the field" is the baseline, not a differentiator.
- Your Local Training Center is a resource. Because the pathway runs through it, it is the natural place to ask about preparation support and the practical steps of scheduling.
For the full eligibility picture, read our breakdown of CMRS/LD requirements and how to qualify, and check testing windows and scheduling before you plan your timeline.
Where Candidates Tend to Lose Points
Without a published pass rate, we cannot quote how many candidates fail. But the blueprint and format point to predictable weak spots. Treat the following as reasoned risk areas based on the exam's design, not as measured failure statistics.
Assuming field habits equal the standard
Crews develop local shortcuts. A closed-book written exam asks for the correct, standards-based answer, which can differ from "how we do it on our site." Candidates who answer from habit rather than from the rule risk missing otherwise familiar questions.
Underinvesting in planning content
Critical Hoist/Lift Plans carries 16 scored items, yet many hands-on riggers spend more time on hitches than on planning documentation. If your daily role rarely involves writing or reviewing lift plans, this block deserves deliberate attention.
Treating Application as one topic
With 30 scored items, Application is large enough to contain many distinct situations. Candidates sometimes study it as a single bucket and discover on exam day that it spans a wide range of scenarios. Break it into the situations you personally see least often and prioritize those.
Ignoring the renewal reality
Certification lasts four years and renewal involves reexamination. Candidates who memorize for a single sitting set themselves up for a harder second round. Building understanding rather than rote recall pays off twice. See our CMRS/LD study guide for approaches that build durable knowledge.
Key Takeaway
Because scoring is scaled and the blueprint is weighted, your best predictor of success is not a pass-rate statistic but your performance by subdimension. Take a diagnostic, rank the five subdimensions by weakness, and weight your hours toward Application and Critical Hoist/Lift Plans first.
Sequencing Your Preparation by Domain
Generic study advice is plentiful; what matters here is how to order the CMRS/LD blueprint. A simple four-week arrangement keeps the heaviest blocks front-loaded while leaving time to integrate everything.
Application and Hitch Configuration
- Start with Rigging Procedures because it holds 45 of the 80 scored items.
- Work scenario-style problems in Application, the largest single block at 30 items.
- Review hitch configuration choices and their effects on the load.
Critical Hoist/Lift Plans
- Study what a critical lift requires and what a plan must cover.
- Connect planning responsibilities to the roles involved in a lift.
Site Awareness/Personnel Safety and Load Stability
- Cover hazards, communication, and personnel protection around the lift.
- Do a focused pass on Load Stability so its 4 items are not given away.
Integration and Timed Practice
- Take full-length closed-book practice sessions within a four-hour window.
- Revisit your lowest-scoring subdimension and retest it.

Who Values the Credential
Understanding the credential's audience also frames what "passing" is worth. The CMRS/LD is tied to the UBC and CICC ecosystem, so its value shows up most clearly among carpenter-affiliated contractors, training programs, and employers who work with UBC members on projects involving significant rigging and lift coordination. Roles that blend rigging expertise with signaling and lift-direction responsibility are where the combined credential makes the most sense.

Frequently Asked Questions
CICC does not publish a verified pass rate for the Certified Master Rigger and Signaler/Lift Director exam. Be cautious of any specific percentage that does not cite a primary source, since several other credentials share the same acronym and their figures do not apply here.
The passing standard is a scaled score of 500 on a 200-800 scale. It is not a raw percentage, and CICC does not publish a raw-score equivalent, so focus on strengthening every blueprint area rather than targeting a specific number of correct answers.
The exam has 100 questions, but only 80 are scored. The other 20 are experimental and unscored, and they are not identified, so you should answer every question as though it counts.
No. The CMRS/LD is a closed-book written examination with four hours allowed and no separate practical exam, so your field knowledge must be demonstrated through written questions.
Application, within Rigging Procedures, is the largest single subdimension at 30 scored items. Rigging Procedures overall accounts for 45 scored items and Rigging Safety for 35, so prioritize Application and then Critical Hoist/Lift Plans, which has 16.
Certification runs for four years, and renewal involves reexamination. Building genuine understanding now makes that future retest considerably easier than relying on short-term memorization.
