The Number: 75% and What It Actually Means
If you are searching for the Resilient Flooring Inspector (RFI) passing score, the answer is simple on its face: the general IICRC passing criterion is 75%. The Institute of Inspection Cleaning and Restoration Certification (IICRC) applies that threshold across its certification examinations, and the RFI written exam falls under it.
What 75% does not tell you is how many questions you can miss. That depends on how many questions your exam form contains, and no current RFI-specific question count has been verified. Anyone quoting a precise "you can miss exactly N questions" figure for this credential is guessing. Treat 75% as a proportion of the total, and aim well above it rather than trying to calculate a minimum.

What You Are Being Scored On
The RFI credential covers resilient flooring from the inspector's point of view. IICRC's public competency description for the credential is organized around four topic areas. These headings are the issuer's published phrases, used here as unweighted preparation scope. They are not issuer-numbered exam domains, they carry no official percentage allocations, and they should not be read as an exhaustive list of what any single exam form will ask.
Domain 1: Classifications within the resilient flooring category
You must be able to tell product families apart and place a given floor in the correct category.
- Recognizing the main resilient classifications as the course presents them
- Distinguishing categories that look similar on the surface but behave differently
Domain 2: Basic raw materials used in the manufacturing process
Inspectors diagnose problems more accurately when they know what a product is made of.
- Connecting raw materials to the finished product's performance
- Understanding why composition influences how a floor reacts to moisture, heat, and cleaning
Domain 3: Common and individual characteristics and properties of the individual classifications
The shared traits of resilient flooring versus the traits unique to each classification.
- Separating properties common to the whole category from those specific to one type
- Applying those properties when evaluating a reported flooring complaint
Domain 4: Manufacture, installation, maintenance, and demolition
The product lifecycle from factory to removal, including maintenance knowledge within the inspection credential.
- How manufacturing and installation decisions show up later as inspectable conditions
- Maintenance practices as they relate to inspection, not as a stand-alone maintenance credential
- Demolition considerations at end of life

What Has to Happen Before You Can Sit the Exam
You cannot simply register for the written exam and show up. The pathway has several fixed steps, and the passing score is only the last gate.
- Earn ISSI first. Introduction to Substrate and Subfloor Inspection (ISSI) certification is required before RFI.
- Complete approved training. The course must be IICRC-approved. The approved-course requirements and locator are available at iicrccert.org.
- Sit the written examination in person. The credential page specifies in-person certification, and the general FAQ places the in-person examination on the final day of the course.
That final-day placement shapes how you should think about the passing score. You will have just absorbed the course material, and your exam happens in the same room, so your preparation window is largely the weeks before class plus whatever review you do each evening. For the complete eligibility picture, read RFI Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Key Takeaway
Because the exam is on the course's last day, do your heavy studying before class begins. Arrive already familiar with the four content areas so classroom time reinforces what you know rather than introducing it for the first time.
Exam Fee, Retest Fees, and the Conflicting Listings
The money side of passing is where published information gets messy, so here is exactly what can and cannot be said.
| Item | What the sources say |
|---|---|
| Initial inspection-exam fee | USD 150, separate from course tuition. This inspection-specific fee supersedes older USD 80 provider listings. |
| Retest fee (main FAQ) | USD 150 for inspection retests. |
| Retest fee (dedicated Retest FAQs) | A general USD 80 retest fee, listed without the inspection exception. |
| Resolved RFI retest price | Not confirmed. Verify the amount with your course provider before you test. |
Notice the two retest figures disagree. The main FAQ names USD 150 for inspection retests, while the dedicated Retest FAQs give a general USD 80 figure that does not mention an inspection exception. Because the two pages conflict, this article does not advertise a single RFI retest price. Ask your provider which amount applies to you, and get it in writing if you can.
Also remember that exam fees are separate from tuition. When you budget, add the course cost, the exam fee, and a contingency for a possible retest. A fuller breakdown lives in RFI Certification Cost 2026: Complete Pricing Breakdown.
Retest Rules and Why Deadlines Differ
Missing 75% is not the end. Two retests are permitted. The complication is how the clock works, because IICRC's own pages describe the window in two different ways.
| Source | How the deadline is described |
|---|---|
| Dedicated Retest FAQs | 45 days from the initial exam scoring date for the first retest, then 45 days from the first retest scoring date for the second. |
| Main FAQ | Two retest opportunities within 45 days of the original examination date. |
These are not the same rule. Under the first reading, each retest gets its own fresh 45-day window that starts from the most recent scoring date. Under the second, both retests must fit inside one window anchored to the original exam date. A candidate who assumes the generous version could miss a deadline entirely.
If you fail the second retest, you cannot simply keep trying. You must re-enroll and take another examination, which means paying for the training pathway again. That is a strong reason to treat the first attempt seriously. Scheduling details are covered in RFI Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Building a 75% Across the Four Content Areas
Because no official domain weights have been published, you cannot responsibly bet on one area to carry you. A safer plan is to build even competence across all four, then spend extra time where the material is densest. This is the one place a study schedule is worth laying out, tied to the specifics of this credential.
Classifications and raw materials
- Learn the resilient flooring categories and what each is made from
- Start here because later topics build on these definitions
Characteristics and properties
- Sort traits into "common to the category" and "unique to one classification"
- This is the area where look-alike answer choices tend to cause trouble
Manufacture, installation, maintenance, and demolition
- Trace how each lifecycle stage can leave an inspectable condition behind
- Review maintenance as it relates to inspection judgment
Mixed review and ISSI refresh
- Take mixed practice sets across all four areas
- Revisit weak spots and confirm retest paperwork before class
Practice under realistic conditions helps. Work through questions on the RFI practice test site so you see how topics are framed, then return to the material behind every miss. For a fuller plan, see RFI Study Guide 2026: How to Pass on Your First Attempt, and keep a condensed reference handy from RFI Cheat Sheet 2026: One-Page Review of Must-Know Facts.
Key Takeaway
Aim for roughly 85% or better on practice sets before exam day. That cushion absorbs unfamiliar wording and the occasional question outside your prepared scope without putting your pass at risk.
What We Cannot Confirm: Question Count and Timer
Two details candidates ask about most are the number of questions and the time limit. For this credential, neither has been verified from a current RFI-specific source. Course hours should not be mistaken for examination time. A course may run for many hours across its days, but that says nothing about how long you will have for the written test itself.
The practical approach is to ask your instructor at the start of class what the exam format is, then plan your pacing accordingly. If you want to gauge your readiness before then, the practice questions here can show you how your accuracy holds up across the four content areas, though they are a study tool and not a replica of any official exam form.
After You Pass: Renewal and Continuing Education
Passing the exam earns the credential, but keeping it requires ongoing effort. Inspectors are subject to annual renewal, plus 14 continuing education credit hours every two years. The continuing education cycle is separate from the annual renewal, so tracking one does not satisfy the other. Renewal fees depend on which certifications you hold, so the amount varies from person to person.

Frequently Asked Questions
The general IICRC passing criterion is 75%. That threshold applies to the written certification examination for this credential.
That depends on the total number of questions on your exam form, and no current RFI-specific question count has been verified. Because the criterion is a percentage, aim well above 75% rather than counting an allowed number of misses.
Two retests are permitted. If you fail the second retest, you must re-enroll and take another examination. Retest deadlines are described differently across IICRC pages, so confirm the exact dates assigned to you.
The sources conflict. The main FAQ specifies USD 150 for inspection retests, while the dedicated Retest FAQs list a general USD 80 fee without the inspection exception. No resolved RFI retest price can be stated, so verify the amount with your provider.
Yes. Introduction to Substrate and Subfloor Inspection (ISSI) certification is required first, followed by approved training and the in-person written examination. See the RFI requirements guide for the full pathway.
