The Number to Beat: 75%
If you are searching for the Color Repair Technician (CRT) passing score, the answer is straightforward: IICRC's retest guidance gives a 75% passing threshold. That is the figure to plan around. This credential, issued through the Institute of Inspection Cleaning and Restoration Certification (IICRC), covers color correction and repair of nylon and wool textiles, so the exam rewards candidates who understand how dyes, fibers, and chemicals interact, not people who memorize a handful of definitions.
A threshold of three quarters means you can miss roughly one question in four and still pass. That sounds forgiving until you consider how the material is built. Color repair draws on chemistry, fiber science, and procedural judgment, and a weak area can quietly cost you more than you expect. If you want a broader view of how demanding the test is in practice, our guide on how hard the CRT exam is walks through the difficulty factors in detail.
What a 75% Threshold Means for This Exam
Percentage threshold, not a scaled score
IICRC states the pass line as a percentage. That framing matters because many credentialing exams report scaled scores with arbitrary ranges. For the CRT, the published language is a plain percentage threshold, so your goal is simple: answer at least three of every four scored items correctly.
What you should not assume
Two details are easy to over-interpret, so treat them carefully:
- Question count: No CRT-specific number of questions has been verified. Do not rely on any figure you see quoted without a source.
- Timed duration: No timed exam length has been verified either. The 45-day figure you will see in the rules is a completion window for live-stream candidates, not the number of minutes you get to sit the test.
Because the format specifics are unconfirmed, the safest strategy is to prepare for the whole curriculum rather than gambling on a narrow slice. Our CRT study guide lays out a full first-attempt approach.
How the passing score connects to pass-rate talk
People often blur the passing score and the pass rate. The passing score is the bar you must clear; the pass rate is how many candidates clear it. Only the first is published in the sources we rely on, and we do not quote a pass-rate figure here. For a careful look at what is and is not known, see CRT pass rate: what the data shows.
Where Your Points Come From: The 11 Curriculum Topics
IICRC's course description names a set of preparation topics. We list them as eleven curriculum domains below. Important caveat: these are unweighted preparation topics, not an official eleven-section exam blueprint with published percentages. IICRC's broader headings for the credential, color theory, practical application, and hands-on techniques, remain valid learning outcomes but do not establish separately weighted exam sections.
Since no weighting is published, you cannot safely skip any area. At a 75% bar, a domain you ignore is a domain that can sink you. For a deeper walk-through of each area, read our complete guide to all 11 CRT content areas.
Domains 1-2: History of Color and Color Theory
These form the vocabulary for everything else. A technician who cannot reason about color cannot diagnose why a repair looks wrong.
- How color is described and why shades appear different under changing conditions
- Applying color theory to decide what a correction needs to accomplish
- Connecting theory to the practical application outcome IICRC lists
Domains 3-5: Natural and Synthetic Dyes, Dye Methods, Types of Dyes
This cluster is the chemistry backbone of the course. Questions here ask you to distinguish what a dye is, how it is applied, and which category fits a given situation.
- Differences between natural and synthetic dye sources
- Dye methods and how they relate to the way color is set in a fiber
- Recognizing dye types and what that implies for repair choices
Domains 6-7: Types of Fibers and Carpet Styles
The credential focuses on nylon and wool, so fiber behavior is central. Carpet construction and style affect how color shows and how repairs blend.
- How nylon and wool take, hold, and lose dye
- How carpet style influences the appearance of a repaired area
Domain 8: Dye Procedures
The most hands-on topic. It connects knowledge to execution and links to IICRC's stated emphasis on selecting dyeing procedures and repairing improperly dyed fabrics.
- Choosing a procedure that fits the fiber and the problem
- Understanding why a procedure fails when it is mismatched to the situation
Domains 9-11: Fading, Contamination or Bleaching, and Color-Affecting Cleaning Agents
These three describe how color is lost, which is the starting point for nearly every repair job.
- Fading as a distinct cause of color change
- Color loss from contamination or bleaching
- Cleaning agents that may affect or remove color from carpet
What IICRC Has Not Published
Honest preparation means knowing the edges of the public information. For the CRT, the following are not verified in the sources used for this article:
- The number of questions on the exam
- The timed duration of the exam itself
- Any domain-by-domain weighting
- A published pass-rate figure
What is clear is the 75% threshold, the retest structure, the fee, and the delivery routes. Build your plan on those. If you see a website quoting a precise question count or pass percentage for the CRT, check it against IICRC directly before trusting it. Our CRT cheat sheet separates confirmed facts from guesses so you can review without second-guessing.
Fees and Deadlines That Surround Your Score
Your score only matters if you sit the exam on time and in the right way. The mechanics differ by delivery route.
| Item | Live-Stream Route | In-Person Route |
|---|---|---|
| Course length | Two days, 14 instructional hours (excluding exam time, lunch, and breaks) | Two days, 14 instructional hours (excluding exam time, lunch, and breaks) |
| Attendance rule | Attend the entire course | Attend the course |
| When you test | IICRC Online Exam Portal, within 45 days after the final course date | Written exam on the final course day |
| Initial exam fee | $80 USD | $80 USD |
| Retest fee | $80 USD each | $80 USD each |
| Course tuition | Separate unless the school bundles it | Separate unless the school bundles it |
Notice what the 45 days is and is not. It is the window in which a live-stream candidate must complete the portal exam after the last course date. It is not the amount of time you get to answer questions. For a full pricing picture including tuition, read the CRT certification cost breakdown, and for scheduling specifics see CRT exam dates, windows, and deadlines.
Key Takeaway
Treat the $80 exam fee as a reason to prepare thoroughly before your first attempt. Every retest costs another $80, and a second failed retest also forces you to re-enroll in the course, which adds tuition on top.
If You Miss the Mark: Retest Rules
A score below 75% is not the end of the road, but the rules are structured and they have teeth.
- Initial attempt: Your first sitting of the exam.
- First retest: Allowed after an initial failure.
- Second retest: Allowed after the first retest if you fail again.
- After a second failed retest: You must re-enroll in the course before trying again.
The 45-day retest clock and a wording wrinkle
IICRC's detailed retest rule gives 45 days from the preceding exam's scoring date for each retest, and a new 45-day period begins after the first retest is scored. However, the general FAQs refer to the exam date rather than the scoring date. That is a real difference in wording. Because the two pages do not match exactly, do not assume which anchor applies to you. Confirm your assigned deadline directly with IICRC so you do not lose an attempt to a miscounted calendar.
Why this changes how you prepare
With only three total attempts before a course re-enrollment, the sensible approach is to treat your first sitting as the one that counts. Use the time between your final class day and the exam to review weak domains rather than rushing straight into the portal. Our first-attempt study guide shows how to structure that review.
Prerequisites That Come Before Any Score
You cannot simply book the CRT exam on its own. IICRC requires CCT or CCMT certification before the CRT. After that, candidates complete approved CRT instruction and then the exam. Some providers may suggest enrollment paths or use inconsistent wording about designations, but those recommendations do not override IICRC's own prerequisite and designation requirements.
If you are still mapping your route, the CRT requirements and eligibility guide explains how to qualify, and CRT training covers how the course fits in. You can also confirm the basics at what CRT stands for if you landed here from a general search.
Sequencing Your Prep Around the Threshold
Because the pass line is 75% across a curriculum that spans chemistry, fibers, and procedure, a sequenced plan helps. This is the one place we lean on a timeline, and it is tied directly to the CRT domains. Adjust the pacing to the days between your course and your exam window.
Foundations: Color and Dyes
- History of color and color theory (Domains 1-2)
- Natural and synthetic dyes, dye methods, and types of dyes (Domains 3-5)
- Why first: later procedure questions assume you already speak this vocabulary
Materials and Procedure
- Types of fibers and carpet styles, focusing on nylon and wool (Domains 6-7)
- Dye procedures and how to match a procedure to a problem (Domain 8)
- Why second: procedure choices only make sense once fiber behavior is clear
Causes of Color Loss and Full Review
- Fading, contamination or bleaching, and color-affecting cleaning agents (Domains 9-11)
- Mixed practice across all eleven topics
- Re-study the domains where you score lowest
Mixed practice is where the 75% bar becomes real. Our CRT practice tests let you see which domains pull your total below the line, and you can return to the main practice test site as often as you need while you tighten weak areas.
After the Score: Renewal and the Master Textile Cleaner Path
Passing is the start of a maintenance cycle. Technician-level certification requires annual renewal and 14 continuing education credit hours every four years. Master and Inspector holders follow a separate requirement of 14 hours every two years. Renewal charges vary with the number and type of credentials you hold, so budget based on your own portfolio.
The CRT also matters for career progression. It is required for the Master Textile Cleaner pathway, but not sufficient by itself, so passing opens a door without completing the journey. To judge whether it fits your goals, compare the worth-it analysis with the earnings overview, and see where the credential leads in CRT jobs.
Frequently Asked Questions
IICRC's retest guidance gives a 75% passing threshold. That is the figure to plan around. A CRT-specific question count and timed exam duration have not been verified, so focus on mastering the full curriculum.
After an initial failure you are allowed two retests. If you fail the second retest, you must re-enroll in the course before attempting again. Each retest costs $80 USD, the same as the initial exam.
IICRC's detailed retest rule gives 45 days from the preceding exam's scoring date, with a new 45-day period after the first retest is scored. The general FAQs instead mention the exam date, so confirm your exact deadline with IICRC.
No. For live-stream candidates, 45 days is the window to complete the online exam after the final course date. It is a completion deadline, not the timed duration of the test, which has not been verified.
No weighting has been published. The eleven topics come from IICRC's course description and are unweighted preparation topics, not an official eleven-section exam blueprint. Study all of them rather than guessing which count most.
Yes. IICRC requires CCT or CCMT certification before the CRT. After that you complete approved CRT instruction and the exam, delivered either live-stream or in person.
