As of 2026-05-13, IICRC's Rug Cleaning Technician (RCT) is the in-plant rug cleaning credential covering Oriental and area rug identification, fiber and dye behavior, full-immersion washing, spot treatment, and controlled drying. The exam is approximately 100 multiple-choice questions with a 75% passing score and an $80 fee, administered proctored in-person only at the end of an IICRC-approved RCT class — there is no online testing window. No prior IICRC credential is formally required, but the Carpet Cleaning Technician (CCT) is recommended preparation. Core content: rug construction and origin identification, wool vs. silk vs. viscose/rayon fiber behavior, acid- and natural-dye colorfastness pretesting, dry-soil removal (dusting), pH-appropriate detergent selection, wash-pit and flat-wash mechanics, urine decontamination, spotting chemistry, centrifuge extraction, and flat/pole drying decisions. Administered by the IICRC (iicrc.org/rct/).

1The most reliable way to confirm that a rug is hand-knotted rather than hand-tufted is to:
A.Check whether the pile feels soft on the surface
B.Look at the back — a hand-knotted rug shows the design mirrored on the reverse with no glue or scrim
C.Inspect the fringe for a serged finish
D.Count the colors used in the field
Explanation: Hand-knotted rugs are built knot by knot through the foundation, so the design is visible on the back at the same resolution as the front. Hand-tufted rugs have a glued cloth scrim covering the back to hold the punched-in yarns in place.
2A rug technician sees a fabric backing glued to the underside of a rug, concealing the structure of the pile yarns. This rug is most likely:
A.Hand-knotted Persian
B.Hand-tufted with a scrim and latex adhesive
C.Kilim flat-weave
D.Machine-woven Wilton
Explanation: Hand-tufted rugs are made by punching pile yarns through a primary cloth with a tufting gun; latex adhesive and a secondary scrim are then applied to lock the tufts in place. The scrim hides the punched yarns from view.
3Knot density in hand-knotted rugs is most commonly expressed in:
A.Stitches per inch (SPI)
B.Knots per square inch (KPSI) or knots per square decimeter
C.Picks per centimeter (PPC)
D.Threads per square millimeter (TPSM)
Explanation: KPSI (knots per square inch) is the standard imperial measure for hand-knotted rug fineness in the U.S. and U.K. market; knots per square decimeter is the metric equivalent commonly used in Iran and Europe.
4The asymmetric knot (Senneh knot) is most strongly associated with:
A.Turkish village rugs from Anatolia
B.Persian city and tribal rugs
C.Tibetan loom-cut rugs
D.Machine-made polypropylene rugs
Explanation: The asymmetric (Persian/Senneh) knot wraps fully around one warp and only halfway around the adjacent warp. It is the dominant knot in Iranian/Persian production and yields finer curvilinear designs.
5The symmetric (Ghiordes) knot is most associated with which weaving tradition?
A.Iranian city rugs such as Kashan and Isfahan
B.Turkish and Caucasian rugs
C.Chinese closed-back rugs
D.Indian Bhadohi production
Explanation: The symmetric Ghiordes knot wraps around two warps with the pile ends pulled between them. It is the traditional knot of Turkish (Anatolian) and Caucasian weavers and is well suited to bolder geometric designs.
6Tibetan and Indo-Tibetan rugs are most often produced using:
A.A symmetric Ghiordes knot tied on cotton warps
B.A continuous loop wrapped around a temporary horizontal rod, then cut to form the pile
C.Hand-tufting with a tufting gun and scrim
D.Jufti knotting over four warps to reduce time
Explanation: The Tibetan technique uses a continuous yarn looped around a metal rod laid across the warps; once a row is complete the rod is slid out and the loops are cut, leaving a row of pile. This is sometimes called the Senneh-loop or Tibetan knot.
7A 'jufti' knot, sometimes found in Khorasan and older Mashhad rugs, is a:
A.Variant in which the knot is tied across four warps instead of two, reducing labor and density
B.Method of double-knotting to increase pile durability
C.Special silk-only knot used only in Hereke rugs
D.Knot used exclusively in kilim flat-weaves
Explanation: The jufti (or 'false') knot is tied over four warps rather than the usual two. It speeds production but produces a coarser, less durable pile and is generally considered a sign of lower-grade or shortcut weaving.
8A kilim is best described as:
A.A hand-knotted pile rug of moderate KPSI
B.A pileless, flat-woven rug produced by slit-tapestry or interlocked-weft techniques
C.A hand-tufted rug with cut-and-loop texture
D.A machine-woven Axminster carpet
Explanation: Kilims are flat-woven (no pile), with patterns produced by manipulating weft yarns of different colors. Slit-tapestry and interlocking-weft methods are the two most common kilim techniques.
9When inspecting a rug, the technician identifies cotton warps and wefts with a wool pile and asymmetric knots at roughly 200 KPSI. This profile most strongly suggests:
A.A Persian city rug from Kashan, Tabriz, or Isfahan
B.A Turkish village kilim
C.A Chinese closed-back rug from the 1980s
D.A modern hand-tufted Indian rug
Explanation: Cotton foundation, wool pile, asymmetric knot, and moderate-to-fine KPSI is the classic profile of a Persian city workshop rug — Kashan, Tabriz, Isfahan, and similar centers.
10A rug has a silk foundation (warp/weft) and a very fine silk pile, with KPSI well above 400. This is most consistent with:
A.A Bhadohi handloom from India
B.A Hereke or Qum silk rug
C.A Tibetan 60-knot wool rug
D.A Belgian machine-woven Wilton
Explanation: Hereke (Turkey) and Qum (Iran) are the two production centers most famous for silk-on-silk rugs at very high KPSI. Both can exceed 400 KPSI and sometimes 1,000+ KPSI in the finest pieces.

About the IICRC RCT Exam

The IICRC Rug Cleaning Technician (RCT) is the professional certification for technicians who clean Oriental and area rugs in a wash plant environment. It covers rug identification and construction (hand-knotted, hand-tufted, machine-woven), fiber identification (wool, silk, cotton, viscose, synthetics), dye stability and colorfastness testing, full-immersion wash-pit methods, in-plant flat washing, spot and stain treatment, and controlled drying and finishing. RCT-certified technicians handle the unique risks of immersing valuable hand-made rugs — dye bleed, cellulosic browning, viscose distortion, and structural damage — that distinguish rug cleaning from in-home carpet cleaning.

IICRC RCT Study Tips from Top Performers

1Learn to distinguish hand-knotted, hand-tufted, and machine-woven rugs from the back — knots, foundation, and how fringe attaches are the giveaway
2Wool vs. viscose is the single most important fiber ID — viscose loses strength and color when wet and looks like silk dry
3Always pretest every color for dye stability before water exposure — acidic rinses and dye stabilizers prevent bleed
4Dry soil removal (dusting) is the first and most important step — most soil in a rug is dry particulate, not wet residue
5Full-immersion pit washing requires pH-appropriate detergent, controlled agitation, and a full rinse — over-alkaline cleaners damage wool and shift dyes
6Cellulosic browning on cotton foundations is a wet-cleaning risk — fast extraction and controlled drying prevent it
7Flat drying vs. pole drying depends on the rug — delicate antiques flat, sturdy modern rugs can pole-dry to speed throughput

Frequently Asked Questions

What is the IICRC RCT certification?

The IICRC Rug Cleaning Technician (RCT) is the professional certification from the Institute of Inspection, Cleaning and Restoration Certification for technicians who clean Oriental and area rugs in an in-plant wash environment. The credential covers rug identification and construction, fiber and dye behavior, colorfastness pretesting, full-immersion and flat washing, spot and stain treatment, and controlled drying. It is distinct from the Carpet Cleaning Technician (CCT) credential, which covers in-home carpet cleaning.

How much does the IICRC RCT exam cost?

The IICRC exam fee for RCT is $80. Candidates must first complete an IICRC-approved RCT course at an approved school — course tuition varies by provider and is paid separately to the school. The class is hands-on and in-person, and the exam is administered at the end of class.

What are the prerequisites for the IICRC RCT exam?

There are no formal prerequisites for RCT — no prior IICRC credential or industry experience is required. However, IICRC recommends completing the Carpet Cleaning Technician (CCT) before RCT, since CCT covers fundamental fiber, soil, and chemistry concepts that RCT builds on. First-time certification requires attending an IICRC-approved RCT class.

What is the IICRC RCT retake policy?

Retake policy is set by the IICRC and the approved school administering the exam. Candidates who do not pass should contact the school where they took the class for retake scheduling and any waiting period or additional fees. Confirm details with the school and the IICRC before the class.

How does IICRC RCT recertification work?

RCT-certified technicians maintain certification through the IICRC's continuing education and renewal cycle (typically every few years), requiring continuing education credits (CECs) and an annual renewal fee. Recertification rules are set by the IICRC and apply across IICRC credentials; consult iicrc.org for the current renewal schedule, CEC requirements, and fees.

Why is the IICRC RCT exam in-person only?

RCT focuses on physical rug handling — identifying rug construction by feel and visual inspection, dye-testing techniques, wash-pit mechanics, fringe handling, and drying decisions — that require hands-on instruction with real rugs. For this reason the IICRC RCT class and exam are delivered exclusively in-person at IICRC-approved schools; there is no online testing option.
