The Number: 70% on a 70-Question Exam
The International Council for Machinery Lubrication (ICML) sets the passing score for the Level I Laboratory Lubricant Analyst (LLA) examination at 70%. The exam consists of 70 multiple-choice questions, administered closed-book with a two-hour limit. That is the entire scoring rule as published: one threshold, applied to the whole exam.
If you came here hoping for a hidden curve, a per-domain minimum, or a scaled-score conversion chart, the public ICML materials do not describe any of those. Nothing in the issuer's published testing documentation suggests you must clear each domain separately; what matters is your overall percentage. That said, because the exam objectives are weighted unevenly, your overall result is still driven far more by some content areas than others, which is why this article spends real time on the domain weighting.
What 70% Means in Practice
On a 70-question exam, a 70% threshold is simple arithmetic: you need 49 correct answers to reach 70%. A score of 48 correct falls just under (about 68.6%). ICML's public documentation does not state whether the exam includes unscored items or how any individual item is weighted, so treat 49 as the working target and aim well above it.
| Correct Answers | Approximate Score | Outcome vs. 70% Cutoff |
|---|---|---|
| 48 of 70 | 68.6% | Below the cutoff |
| 49 of 70 | 70.0% | Meets the cutoff |
| 56 of 70 | 80.0% | Comfortable margin |
| 63 of 70 | 90.0% | Strong margin |
Two hours for 70 questions works out to a little under two minutes per item on average. That is generous for recall questions but tight enough that you should not linger on calculation-style problems. A sensible approach is to answer everything you can resolve quickly, flag the rest, and return with the time you have banked.

Format and Conditions That Shape Your Score
The questions are multiple-choice and the exam is closed-book. There are no reference materials to lean on, so everything you need must be retrievable from memory: terminology, test method purposes, units, acceptance logic, and the reasoning behind laboratory procedures.
The content is aligned with ISO 18436-5, Category I, Annex A, and the four exam headings and their percentages are the official objectives published in ICML's Level I LLA Body of Knowledge. This alignment tells you something useful about question style: the exam tests the practical knowledge of a Category I laboratory analyst, someone who runs routine lubricant tests accurately and handles the supporting work of samples, reagents, and instruments, rather than someone designing programs or interpreting complex failure investigations.
Where Your Points Come From: The Four Domains
Because 70% is an overall threshold, domain weighting is the most useful lever you control. The official breakdown for the four headings is:
| Domain | Weight |
|---|---|
| Sample handling and preparation | 30% |
| Lubricant health monitoring | 30% |
| Reagent Management | Remaining share (see Body of Knowledge) |
| Instrument Calibration | Remaining share (see Body of Knowledge) |
Sample handling and preparation and Lubricant health monitoring are the joint-largest areas at 30% each, which together account for 60% of the exam. That means roughly 42 of the 70 questions, if the exam mirrors the published weights, come from just two domains. The other two domains, Reagent Management and Instrument Calibration, share the remaining 40%. For the precise split, consult the ICML Level I LLA Body of Knowledge in the LLA I section of ICML Certifications.
Sample Handling and Preparation (30%)
This domain covers what happens between a sample arriving at the lab and the moment it goes into an instrument. Errors here corrupt every downstream result, which is why it is weighted so heavily.
- Recognizing how sample integrity can be compromised before testing begins
- Preparing samples consistently so results are repeatable
- Understanding why representative sampling and proper preparation matter to every later test
- Documenting and tracking samples through the laboratory workflow
Lubricant Health Monitoring (30%)
This is the analytical core: understanding what the tests tell you about the condition of the oil and the machine it came from.
- Knowing which properties indicate lubricant degradation, contamination, or wear
- Connecting a test result to the condition it signals
- Recognizing when a result looks abnormal and needs verification
- Understanding the purpose behind routine laboratory test methods
Reagent Management
Questions here test whether you can keep the chemistry in your lab trustworthy.
- Storage, labeling, and handling of reagents
- Awareness of reagent shelf life and the consequences of using degraded materials
- Safe practice and record-keeping around laboratory chemicals
Instrument Calibration
Calibration questions probe whether you understand why measurements can be trusted and what to do when they cannot.
- The purpose and basic logic of calibration and verification
- Recognizing signs that an instrument may be out of tolerance
- Keeping calibration records and acting on them appropriately

Key Takeaway
Do not treat the smaller domains as optional. With only a 30% margin of error across the whole exam, losing most of Reagent Management and Instrument Calibration can sink an otherwise strong performance in the two heavyweight domains.
Paper vs. Online: Same Score, Different Conditions
The 70% threshold is identical whether you test on paper or online. What changes is the environment, and some of those differences can affect how you perform on calculation-style questions.
| Factor | Paper Testing | Online Testing |
|---|---|---|
| Proctoring | Proctored paper exam | Live ProctorU proctoring |
| Calculator | Basic nonprogrammable scientific calculator permitted | No external calculators allowed |
| Location | Proctored testing session | Private room required |
| Identification | Per ICML paper testing terms | Government photo ID required |
| Equipment | Provided testing setup | Compatible computer with webcam, microphone, and speakers |
| Standard fee | USD 295 first attempt | USD 295 first attempt |
The calculator rule deserves attention. If you plan to test online, practice any arithmetic you may encounter without an external calculator. If you test on paper, bring only an approved basic nonprogrammable scientific model. Review the full rules in ICML's Terms and Conditions for Online Testing and Terms and Conditions for Paper Testing, along with the ICML Exam Procedures, before you schedule. For timing and logistics, see LLA Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
If You Miss the Cutoff: Retake Rules and Costs
Falling short of 70% is recoverable, but the rules are firm and the costs add up.
- Two retakes are permitted after an initial attempt.
- At least 30 days must separate attempts.
- Three consecutive failures require a 12-month wait before you can submit a new first-time application, and that new application carries the full fee.
- Standard pricing is USD 295 for the first exam and USD 175 for a retake. Temporary country-specific prices may apply.

Eligibility Gates You Must Clear First
The passing score only matters once you are approved to sit the exam. ICML requires:
- At least 12 months of laboratory-based lubricant testing and analysis experience, including at least 1,200 hours of actual testing or analysis.
- 24 documented hours of formal training aligned with the Level I LLA body of knowledge.
Online or recorded training, exercises, laboratory tasks, practice exams, and review may contribute at most four of those 24 training hours. Training records must include your name, the instructor's name and signature, dates, and hours, and you should verify that each instructor holds current certification at the level taught. ICML does not endorse or designate any particular training course as official or approved, so be skeptical of any provider claiming otherwise. Full details are in LLA Requirements 2026: Eligibility, Prerequisites & How to Qualify, and you can explore options in LLA Training.
Sequencing Your Prep Around the Cutoff
Because 60% of the exam sits in two domains, a prep plan should front-load them and leave the smaller domains for consolidation. One short, domain-driven sequence:
Sample handling and preparation
- Build a clear mental model of how sample errors propagate into test results
- Review the body of knowledge objectives for this heading line by line
Lubricant health monitoring
- Link each test to the condition it indicates
- Practice interpreting abnormal results and explaining why
Reagent Management and Instrument Calibration
- Cover both smaller domains fully; they decide close results
- Practice any needed arithmetic without an external calculator
Timed mixed practice
- Run full 70-question sets under a two-hour limit
- Aim consistently above 70% before booking your date
For the complete method, including how to turn the Body of Knowledge into a checklist, see the LLA Study Guide 2026: How to Pass on Your First Attempt. To gauge your readiness against exam-style items, work through the questions on the LLA Exam Prep practice test site, and use its timed sets to rehearse the two-hour format.
After You Pass: Three-Year Clock
A passing score earns a credential that lasts three years. Renewal requires a completed application, the recertification fee (USD 175 at standard pricing), and 15 approved recertification points earned during the active period, with no significant interruption in relevant employment. Ordinary employment earns four points per year, capped at 12, and up to three additional points can come from the issuer's listed employment-related best-practice activities. Training, conferences, publications, and presentations can also qualify.
ICML membership can soften the cost. Standard membership is free for current certified professionals; Premier dues are USD 100 annually for certified professionals (USD 140 for non-certified) and include a USD 50 exam or recertification credit, while the three-year certified option costs USD 260 and includes a USD 150 credit. Credits apply to qualifying invoices generated during the membership term and expire when it ends. Details are on the ICML Membership page.
If you are weighing the payoff, the U.S. Bureau of Labor Statistics reports a median annual wage of USD 60,390 for chemical technicians as of May 2025. That is a broad occupational benchmark, not an LLA-specific figure, and it does not measure any certification premium. For a careful treatment, see the LLA Salary Guide 2026: Complete Earnings Analysis and Is the LLA Certification Worth It? Complete ROI Analysis 2026, and browse LLA Jobs for the kinds of laboratory roles where the credential is relevant. ICML also distinguishes this laboratory-focused credential from the field-focused MLA in its What Exam is Right for Me? guide, which is worth reading if you are unsure which path fits your job.
