Direct answer: IICRC certification is a professional credential for cleaning, inspection, and restoration technicians, issued by the IICRC — the Institute of Inspection, Cleaning and Restoration Certification, a nonprofit standards body. You earn one by taking an IICRC-approved course and passing the IICRC exam for that category. The exam fee is $80 for most certifications ($150 for AMRT and the inspection exams), the passing score is 75%, and certification stays active through an annual renewal fee plus 14 continuing education hours every four years (every two years for Master and Inspector certifications). The entry credential for water work is WRT (Water Damage Restoration Technician), which has no prerequisites.
What IICRC certification is
The IICRC does two jobs. It writes the industry’s standards — the ANSI/IICRC S500 for professional water damage restoration is the best known — and it certifies the technicians who work to those standards. A certification means the holder sat through an approved course in that category and passed a proctored exam on it. The certification belongs to the person, not the company: a technician who changes employers takes the card with them.
One boundary worth stating plainly: IICRC certification is a private professional credential, not a government license. Some states separately license specific work, mold remediation especially. The card and the license are different things, and holding one does not give you the other.
The main certifications
The IICRC certifies across cleaning, inspection, and restoration, but the restoration core is a short list. Courses run one to five days depending on the category, in person or by live stream.
| Certification | What it covers | Prerequisite |
|---|---|---|
| WRT — Water Damage Restoration Technician | Water damage, its effects, and techniques for drying structures: water categories and classes, extraction, and drying science. The entry point for water work. | None |
| ASD — Applied Structural Drying Technician | Advanced drying of structures after water damage, beyond the WRT foundation. | WRT |
| AMRT — Applied Microbial Remediation Technician | Mold and sewage remediation. Four-day course; the exam fee is $150, not $80. | WRT |
| FSRT — Fire and Smoke Restoration Technician | Fire and smoke damage restoration. | None |
| OCT — Odor Control Technician | Odor sources and deodorization. A one-day course. | None |
| HST — Health and Safety Technician | Health and safety practice on restoration and remediation jobs. | None |
| CPT — Contents Processing Technician | Packing, handling, and processing of contents after a loss. | None |
Beyond the technician list sit two different kinds of credential. MRS (Mold Remediation Specialist) is experience-based rather than course-based: no class, but twelve months of verifiable mold remediation field work, then a 100-question exam with a 79% pass mark. It runs on a two-year term instead of the annual one. And the Master designations — Master Water Restorer, Master Fire and Smoke Restorer, and Master Textile Cleaner — are tracks earned over time by stacking the required certifications and years of certified service. Master Water Restorer, for example, requires WRT, ASD, AMRT, HST, and a carpet-side certification, plus at least three consecutive years as an IICRC-certified technician. Holding all three Master designations is the Triple Master.

What we actually ran, what it measured, and what it means for a restoration shop — every week, including the flops.
How to get certified
1. Pick the certification. For water work, that means WRT first — it has no prerequisites, and it is the required prerequisite for ASD and AMRT.
2. Take the course at an IICRC-approved school. Only approved schools and instructors can deliver certification courses. Courses run in person and by live stream; you must attend every day in full, or you forfeit eligibility.
3. Register for the exam and pay IICRC’s exam fee. $80 for most certifications, $150 for AMRT and inspection exams, paid to the IICRC — separate from the school’s tuition.
4. Sit the exam. In-person students test on the last day of class. Live-stream students test through the IICRC Online Exam Portal, within 45 days of the course’s last day. The passing score is 75%. If you fail, you get two retest opportunities within 45 days of the exam date, at the same fee.
5. Wait for processing. Certification processing takes four to six weeks from exam completion, and the certificate mails seven to ten business days after that.
What it costs
Three separate costs, paid to two different places. Course tuition goes to the approved school and varies by school and category. The exam fee goes to the IICRC: $80 per exam, $150 for AMRT and inspection exams, and retests cost the same as the first attempt. The annual renewal fee keeps the certification active afterward; it is billed per technician based on the number and type of certifications held — IICRC’s own examples run $46 to $58 a year.
Keeping it: renewal and continuing education
Certification is not permanent. Renewal is annual and required — let it lapse and the credential is no longer active. Alongside the fee, certified technicians must complete 14 CECs (continuing education credit hours) every four years. Master and Inspector certifications run a faster clock: 14 CECs every two years. CECs come from approved courses, live-stream certifications taken for credit, and industry events, and the technician is responsible for submitting the documentation. A lapsed certification is not gone forever: expired less than 24 months, you request a renewal invoice; past 24 months, reinstatement goes through a separate process and may carry added fees.
Certified Firm: the company-level credential
Individuals hold certifications; companies hold Certified Firm status. A Certified Firm needs current liability insurance, at least one active Certified Technician on staff, and a completed application. The application fee is $25 plus a prorated amount, and renewal is $199 a year. Each business location must qualify separately, with its own certified technician who is not listed for another location — and because certifications follow the person, a firm whose one certified technician leaves loses the basis for its status until another is on staff.
What the card is worth in pay
The basics above are what the credential is. What it pays is a separate, measurable question — and the honest measured answer is more interesting than the brochure one. We priced IICRC certifications against real restoration job postings, held role and city still, and published the full dataset: the pay premium is a wide interval around zero for the common cards, which is exactly why the method matters more than the slogan. The study: What an IICRC Card Is Worth, Measured. Field companions: the IICRC Van Pocket Card and IICRC S500 in the Van.
Frequently asked questions
What does IICRC stand for? Institute of Inspection, Cleaning and Restoration Certification — a nonprofit organization for the inspection, cleaning, and restoration industries. It develops standards, including the ANSI/IICRC S500, and certifies technicians who complete its approved courses and exams.
How much does IICRC certification cost? Course tuition is set by the approved school and varies. On top of tuition, the IICRC exam fee is $80 for most certifications and $150 for AMRT and inspection exams; retests cost the same. Keeping the certification active costs an annual renewal fee, billed by the number and type of certifications you hold.
How long does it take to get IICRC certified? The course itself runs one to five days depending on the certification — WRT is three days. After you pass the exam, certification processing takes four to six weeks, and the certificate mails seven to ten business days after processing.
Do IICRC certifications expire? Yes. Technician certifications renew every year, with an annual fee and 14 continuing education hours due every four years; Master and Inspector certifications need their 14 hours every two years. A certification that passes its renewal is not active until renewed or reinstated.
What is the first IICRC certification to get? WRT — Water Damage Restoration Technician. It has no prerequisites, covers the foundations of water damage and drying, and is the required prerequisite for the advanced water certifications, ASD and AMRT.
Is IICRC certification a license? No. It is a private professional credential, not a state license. Some states license mold remediation and similar work separately; an IICRC card does not substitute for a required state license.
