IICRC Certification: What It Is, Which Credentials Exist and How Restoration Techs Get Certified

The IICRC — the Institute of Inspection Cleaning and Restoration Certification — is a non-profit certification body for the inspection, cleaning and restoration industries.

It was founded in 1972, originally as the International Institute of Carpet and Upholstery Cleaning Inc. (IICUC).

On its About page in October 2026, it counted more than 49,000 active Certified Technicians and more than 6,500 Certified Firms worldwide.

It is a certifying body, not a school: the IICRC owns no schools and has no instructors on staff, and it approves independent schools and instructors that apply and meet the criteria its board of directors sets.

Certification, in IICRC's own definition of the path, means a person attended an IICRC-approved course, passed the written examination and documented skills in the specific subject.

One credential breaks that pattern — the experience-based Mold Remediation Specialist, covered in the list below.

The credential belongs to the individual, not the employer.

IICRC's own wording is that your certifications follow you and not your company, so they stay in your name when you change employers — worth remembering if an employer offers to put you through a course, because the credential stays yours either way.

Firms can be certified too: the 6,500 figure above counts IICRC Certified Firms — a company-level listing, separate from a technician's personal certifications.

IICRC's Certifications Offered page listed 28 credentials as of October 2026, grouped into three divisions: Cleaning, Inspection and Restoration.

The full acronym list runs: AMRT, ASD, BMI, BCI, CCMT, CCT, CDS, CPT, CRT, FCT, FSRT, HCT, HST, ISSI, LCT, MRS, OCT, RCT, RFI, RFMT, RRT, SCI, SMT, TCST, UFT, WFMT, WLFI and WRT.

The restoration division is the one restoration work draws on, and IICRC's restoration training page lists its credentials: AMRT, ASD, BMI, CDS, CPT, FSRT, HST, OCT, RRT, TCST and WRT.

If you are mapping these onto the job itself, our restoration technician career guide covers the role; this page stays on the credentials.

• WRT — Water Damage Restoration Technician. IICRC says WRT holders can handle a residential water loss, explain Category 2 vs 3 water to an adjuster and adjust drying plans based on the science of drying. It has no prerequisites.
• ASD — Applied Structural Drying Technician. Requires the WRT first.
• AMRT — Applied Microbial Remediation Technician. Requires the WRT first, and covers mold and sewage remediation techniques for people in restoration, property management and indoor environmental quality work.
• CDS — Commercial Drying Specialist. Requires the WRT, and covers commercial, industrial, institutional and complex residential drying.
• FSRT — Fire and Smoke Damage Restoration Technician. Covers scoping, mitigation, cleaning, deodorization, subrogation, spoliation and documentation of fire- and smoke-damaged structures and contents.
• HST — Health and Safety Technician. Covers OSHA standards, inspections and citations, recordkeeping, PPE, hazard communication, hazardous materials, confined spaces and bloodborne pathogens.
• OCT — Odor Control Technician. The odor-control credential on the restoration track.
• CPT — Contents Processing Technician. Has no prerequisites, runs live-stream and in-person, and is not required for any Master designation.
• TCST — Trauma and Crime Scene Technician. Built on ANSI/IICRC S540, with no prerequisites.
• RRT — Carpet Repair and Reinstallation Technician. Covers carpet repairs and taking up and reinstalling carpet.
• BMI — Building Moisture Inspection. The moisture-inspection credential on the restoration track.

On the cleaning side, IICRC's cleaning-division list includes CCT, CRT, CCMT, FCT, HCT, LCT, RFMT, RCT, SMT, UFT and WFMT.

Several of these get their own credential pages on IICRC's site — the Carpet Cleaning Technician (CCT), the Commercial Carpet Maintenance Technician (CCMT), the Upholstery and Fabric Cleaning Technician (UFT) and the Color Repair Technician (CRT).

For all three Master designations, the CCT can be swapped for the CCMT.

The Inspection division fills out the remainder of the list; IICRC's Certifications Offered page shows each credential's division and details, and its course locator lists current class options.

The Mold Remediation Specialist (MRS) is the list's outlier.

It has no course: applicants need at least one year of verifiable hands-on mold remediation field experience, and supervision or inspection work does not count unless the applicant personally performed remediation.

The MRS is ANAB-accredited — unlike the older Mold Removal Specialist, which was never accredited and is no longer offered.

The course-based AMRT sits on the other side of that line: IICRC notes it is not an accredited certification.

One naming wrinkle to know before you book anything: IICRC's own pages are inconsistent about the WRT's name.

Its WRT page says Water Damage Restoration Technician (WRT), while the ASD, AMRT and CDS pages list the prerequisite as Water Restoration Technician (WRT) — the same credential under two wordings.

Delivery varies by credential.

The October 2026 list marks AMRT, ASD, LCT, RCT, RFI and WLFI as in-person only; most other certifications, including the WRT, FSRT, OCT, HST, CCT, UFT, RRT, CDS, CPT and TCST, are offered both live-stream and in-person.

Three things stand between you and the credential, and IICRC states them plainly: attend an IICRC-approved course, pass the written exam and document skills in the specific subject.

Classes run from one to five days depending on the course.

The path looks like this:

1. Pick the credential and check its prerequisites. The WRT has none; the ASD, AMRT and CDS all require the WRT first.
2. Find a class through the IICRC course locator at iicrccert.org. IICRC staff will not recommend a specific instructor or school. Its approved-schools list includes in-house schools run by franchisors and large restorers, alongside independent training companies and the Restoration Industry Association. The restorer and franchisor entries include Belfor University, Servpro Industries LLC, Paul Davis, Puroclean Academy, Rainbow Restoration and Rytech. The locator also lists an Apprentice Skills Program Water Restoration (ASPWR, offered in Spanish), an Apprentice Skills Program House Cleaning (ASPHC) and a combined WRT/ASD course option.
3. Attend the course. An IICRC live-stream class is not a recording: it is taught in real time by an IICRC Approved Instructor, attendance is taken daily, and missing any day forfeits your exam eligibility. Live-stream classes are capped at 20 people.
4. Pass the exam. In-person students sit the exam on the last day of class. Live-stream students take it through the IICRC Online Exam Portal within 45 days of the course's last day, and they register and pay IICRC's exam fee separately through their IICRC account.
5. Wait on processing. IICRC says certification processing takes 4–6 weeks from exam completion, and mailing the certificate adds another 7–10 business days.

The exam is written, and the pass mark on standard IICRC certification exams is 75%.

A candidate who fails gets two retests; after a second failed retest, IICRC requires re-enrolling in the course.

The exam fee is $80 for the initial exam and each retest in IICRC's US pricing, except the AMRT and the inspection exams, which cost $150.

Our research found no list of the credentials restoration employers require, no verified count of how many job postings mention IICRC certification, and no verified pay premium attached to holding one.

Treat any percentage or dollar figure attached to that question as unproven until you can trace it to a survey you can actually read.

What the research does show is structural.

Certifications are issued to the individual, so they stay with a tech between employers.

IICRC's approved-schools list includes the in-house schools of large restorers and franchise brands, so several of the same companies that hire restoration techs also train them inside the IICRC system.

Which credential a specific employer wants is a question for that employer's posting and interview.

On the insurance-program side, our research verified one signal: Sedgwick's public managed-repair network page describes its network as 'certified mitigation and damage restoration contractors', but the page does not publish specific IICRC requirements.

That was the only program-side credential requirement our sources turned up as of October 2026, so ask about a program's credential expectations directly during hiring rather than assuming them.

The practical shortcut is to map the credential to the loss type you want to work.

Water: the WRT, then the ASD for structural drying and the CDS for commercial drying.

Mold: the AMRT, or the MRS once you have the field experience it demands.

Fire and smoke: the FSRT, with the OCT for odor control.

Contents: the CPT.

Trauma and crime scene: the TCST.

Safety knowledge that applies across loss types: the HST.

Above the single credentials, IICRC's certification ladder has two levels built from them: Journeyman and Master.

There are three Master designations — Master Water Restorer (MWR), Master Fire and Smoke Restorer (MSR) and Master Textile Cleaner (MTC) — each with an intermediate Journeyman level: Journeyman Water Restorer (JWR), Journeyman Fire and Smoke Restorer (JSR) and Journeyman Textile Cleaner (JTC).

IICRC says only 3.7% of its constituents hold a Master designation.

A Master designation requires at least three consecutive years as an IICRC Certified Technician plus the specific certifications for that track.

The Journeyman step lands earlier: complete the track's entry certifications and reach at least 12 months certified, and you hold the Journeyman level while you bank the rest.

IICRC lays out each track like this:

1. Master Water Restorer (MWR). The Journeyman Water Restorer (JWR) step takes CCT or CCMT, plus RRT and WRT, and at least 12 months certified. The Master step adds AMRT, HST and ASD, plus at least 3 years certified.
2. Master Fire and Smoke Restorer (MSR). The Journeyman Fire and Smoke Restorer (JSR) step takes FSRT, UFT and OCT, and at least 12 months certified. The Master step adds HST and CCT or CCMT, plus at least 3 years certified.
3. Master Textile Cleaner (MTC). The Journeyman Textile Cleaner (JTC) step takes CCT or CCMT, plus UFT and one of OCT, RRT or CRT, and at least 12 months certified. The Master step requires OCT, RRT and CRT together, plus at least 3 years certified.

Carrying a Master designation raises the renewal workload along with the title: Master designation holders must complete 14 CECs every two years, rather than every four years for regular technicians.

An IICRC certification stays active only if you maintain it.

IICRC's requirements are two: pay the annual renewal fee, and earn continuing education credits (CECs).

The CEC clock runs on 14 hours.

Regular technicians need 14 CECs (hours) every four years, and Master and Inspector certifications need the same 14 hours on a two-year cycle.

CECs must be up to date before IICRC can renew you, and technicians are responsible for sending their own CEC documentation to IICRC at [email protected] — IICRC lists CEC-earning events on its CEC events site.

The renewal fee is not one number.

IICRC says it depends on the number and type of certifications a tech holds, and its own FAQ example shows $46 for one technician and $58 for another.

If a certification lapses, the fix depends on how long it has been expired.

Expired less than 24 months, you request a renewal invoice.

Expired more than 24 months, you request reinstatement instead, which may carry fees.

IICRC certification is generally voluntary: our research found no federal law requiring it for restoration technicians, and IICRC credentials are voluntary unless a state law, an employer, a franchisor or an insurance program requires them.

A credential is not a license, and the difference matters where a state licenses the work itself.

IICRC's own guidance to mold businesses is that licensing rules vary by county, city and state; on its MRS FAQ, it does not claim the credential is legally required to open a business.

State law is where certification can become a condition of doing the work, and two verified examples show the pattern.

Virginia's Consumer Protection Act — Virginia Code section 59.1-200(A)(81) — bans selling or offering residential mold remediation services without a mold remediation certification from a nationally or internationally recognized certifying body, and without following EPA mold guidance, ANSI/IICRC S520 or an equivalent ANSI-accredited standard.

The statute does not name the IICRC as the only certifier, and the current S520 edition is the Fourth Edition, 2024.

Connecticut names certifiers, though not the IICRC alone.

Since October 1, 2026, Public Act 26-100 has required a contractor doing mold remediation to attest, before it gets a home improvement contractor certificate, that it is certified in mold remediation by the IICRC, NORMI or another organization the Department of Consumer Protection (DCP) commissioner approves.

The DCP's mold remediation page lists NORMI and IICRC certification for residential mold remediation under a Home Improvement Contractor registration, and says commercial mold remediation is not covered under that registration.

Two cautions follow from those examples.

A state requirement that accepts any recognized certifying body is not a requirement to hold one specific credential.

And an IICRC certification does not take the place of a state license: where a state licenses mold remediation or asbestos work, that licensing is its own state-by-state question, separate from certification.

The standards side runs on similar logic.

The ANSI/IICRC standards are voluntary consensus standards that IICRC describes as accepted as the industry's 'Standard of Care' — professional benchmarks to work to rather than statutes with penalties attached, even though statutes such as Virginia's can reference one by name.

Career information, not licensing, legal, insurance or safety advice. Requirements, fees and rules change — confirm current certification and licensing requirements with the IICRC and with the state agency for the state you work in before you enroll, test, renew or turn work down.
