OpenExamPrep

The NCCER Tile Setter / Tile Finisher program is a competency-based craft curriculum with multiple-choice module knowledge tests plus hands-on performance verifications rather than one fixed national exam. Module tests are commonly passed at 70% or higher, with exact standards set by the accredited training sponsor. Content spans trade safety and respirable crystalline silica controls, tools, construction math and layout (3-4-5 squaring, estimating), substrates and waterproofing, setting materials (modified and unmodified thinset, medium-bed, epoxy), setting and lippage control, and grouting. It aligns with the TCNA Handbook and ANSI A108/A118/A136 standards. This 100-question bank provides original practice across all of these areas with explained answers.

1Cutting, grinding, or dry-mixing tile, mortar, or concrete releases a hazardous dust regulated by OSHA. What is this dust called?
A.Respirable crystalline silica
B.Asbestos fiber
C.Portland fume
D.Volatile organic compound
Explanation: Tile, mortar, grout, and concrete contain crystalline silica. When cut or ground dry, they release respirable crystalline silica, a fine dust that can cause silicosis and lung cancer and is regulated by OSHA 29 CFR 1926.1153. Wet cutting and dust collection control it.
2Which control is the single most effective way to reduce respirable silica dust when cutting tile with a power saw?
A.Wetting the blade and material with a continuous water supply
B.Working faster to finish sooner
C.Pointing a box fan at the work
D.Sweeping the dust up immediately after
Explanation: Integrated water delivery (wet cutting) keeps the dust from becoming airborne and is the primary engineering control for tile saws under OSHA's silica standard. It is far more effective than respirators alone, which are the last line of defense.
3OSHA's permissible exposure limit (PEL) for respirable crystalline silica is which value, averaged over an 8-hour day?
A.50 micrograms per cubic meter (0.050 mg/m3)
B.500 micrograms per cubic meter
C.5 milligrams per cubic meter
D.5 micrograms per cubic meter
Explanation: OSHA's construction silica standard (29 CFR 1926.1153) sets a PEL of 50 micrograms per cubic meter of air as an 8-hour time-weighted average, with an action level of 25 micrograms per cubic meter. Tile cutting can exceed this without controls.
4A wet saw is most commonly used in tile work to do what?
A.Make straight and miter cuts in tile while controlling dust and heat
B.Mix thinset mortar
C.Apply grout to joints
D.Level an out-of-flat substrate
Explanation: A wet saw uses a water-cooled diamond blade to make clean straight, plunge, and miter cuts in ceramic, porcelain, and stone tile. The water cools the blade and suppresses silica dust.
5A snap cutter (score-and-snap tile cutter) is best suited for which task?
A.Straight cuts on standard ceramic wall and floor tile
B.Cutting natural stone slabs
C.Cutting curved openings around a pipe
D.Grinding tile edges smooth
Explanation: A manual snap cutter scores the glaze with a carbide wheel and then snaps the tile along the score line. It is fast and dust-free for straight cuts in standard ceramic tile but struggles with hard porcelain, stone, and curves.
6When mixing thinset mortar with a drill and paddle, which practice reduces airborne silica and produces a proper mix?
A.Add powder to water at low speed and avoid whipping air into the mix
B.Pour water into a mound of dry powder and mix at the highest speed
C.Mix dry powder alone first at high speed to fluff it
D.Use hot water to speed the cure before adding powder
Explanation: Adding the powder slowly into the measured water at low mixer speed limits dust clouds and prevents air entrainment, giving a smooth, lump-free mortar. High speed whips in air and raises dust; manufacturer water ratios must be followed.
7After mixing thinset, many products require a short wait before use so the chemicals fully wet out. What is this rest period called?
A.Slaking
B.Curing
C.Slumping
D.Efflorescence
Explanation: Slaking is the manufacturer-specified rest (often about 5-10 minutes) after initial mixing that lets the polymers and cement fully hydrate. The mortar is then briefly remixed before troweling. Skipping it can weaken the bond.
8The working time during which freshly troweled thinset can still bond a tile before it skins over is known as the:
A.Open time
B.Pot life of the bucket
C.Set time
D.Dwell time
Explanation: Open time is how long the combed mortar on the substrate stays wet and tacky enough to bond. If the surface skins over and no longer transfers to the tile, the mortar is past its open time and must be removed and re-troweled.
9A tile setter combs thinset and turns away for several minutes; the ridges have crusted and no longer transfer to the back of the tile. What should be done?
A.Scrape off the skinned mortar and apply fresh mortar
B.Press the tile harder to break the skin
C.Mist the ridges with water and continue
D.Add grout over the skin to fill voids
Explanation: Once mortar skins over, its open time has passed and it will not bond reliably. The correct action is to scrape it off and re-comb fresh mortar so the tile bonds to wet, sticky ridges. Adding water or pressing does not restore the bond.
10Which ANSI standard family covers the installation methods (workmanship) for ceramic tile, while the A118 family covers the setting and grouting materials?
A.ANSI A108
B.ANSI A137
C.ANSI A326
D.ANSI Z87
Explanation: ANSI A108 specifies installation and workmanship (such as required mortar coverage), and ANSI A118 specifies the material performance of mortars, grouts, and membranes. Together they are referenced throughout the TCNA Handbook.

About the NCCER Tile Exam

The NCCER Tile Setter / Tile Finisher program is a competency-based craft curriculum that prepares trainees to install ceramic, porcelain, natural stone, glass and mosaic tile to industry standards. Trainees typically complete the NCCER Core Curriculum first, then progress through tile modules covering trade safety, tools and equipment, construction math and layout, substrates and surface preparation, setting materials, setting and grouting techniques, waterproofing and movement joints. Each module is assessed with a multiple-choice written knowledge test and a hands-on performance verification, and credentials stack as modules are completed. The technical content aligns with the TCNA Handbook and ANSI A108, A118 and A136 standards used across the U.S. tile industry.

Assessment

Competency-based craft training. Each tile module has a multiple-choice written knowledge test plus a hands-on performance verification. There is no single fixed national tile exam; question counts and credentials accumulate module by module.

Time Limit

NCCER Tile Study Tips from Top Performers

1Learn when to use unmodified vs modified thinset: unmodified is typically required between two impervious layers (such as porcelain over a waterproofing membrane) because trapped modified mortar cannot cure properly.
2Memorize trowel-to-coverage logic: choose a notch that gives at least 80% mortar contact on dry interior floors and 95% on wet and exterior areas, and back-butter large tile to reach it.
3Practice the 3-4-5 method until it is automatic: a triangle measuring 3, 4 and 5 units forms a perfect 90-degree corner for squaring a room or checking working lines.
4Tie grout choice to joint width: use unsanded grout for narrow joints (about 1/8 inch or less) and sanded grout for wider joints, and know that epoxy grout resists stains and chemicals.
5For wet areas, study the membrane standards: waterproofing falls under ANSI A118.10 and crack isolation under A118.12, and movement joints follow TCNA EJ171.
6Treat silica as an everyday hazard: always wet-cut, use dust collection, and wear an appropriate respirator, because dry cutting tile can exceed OSHA's respirable crystalline silica limits.

Frequently Asked Questions

Is there one national NCCER tile exam?

No. NCCER tile training is competency-based and modular. Each module has its own multiple-choice written knowledge test plus a hands-on performance verification, and credentials stack as you complete modules rather than from a single fixed exam.

What passing score do NCCER module knowledge tests use?

Module knowledge tests are commonly passed at 70% or higher. The exact passing standard, time limit and any retest policy are set by your NCCER-accredited training sponsor or assessment center.

What standards does NCCER tile content follow?

The technical content aligns with the TCNA Handbook and ANSI standards, including ANSI A108 (installation), A118 (setting and grouting materials such as A118.4 modified thinset, A118.10 waterproofing, A118.12 crack isolation) and A136 (adhesives).

Do I need the NCCER Core Curriculum before tile modules?

Yes, in most programs. The Core Curriculum covers basic safety, construction math, hand and power tools and construction drawings, and is the prerequisite for Level 1 craft modules including tile.

Why is silica safety emphasized in tile work?

Cutting and grinding tile and mortar releases respirable crystalline silica, which is regulated by OSHA. Wet cutting, vacuum dust collection and respirators are used to keep exposure below the permissible limit, so silica controls appear throughout tile safety content.

Are these official NCCER, Pearson or TCNA questions?

No. These are original OpenExamPrep practice questions written to match the knowledge areas of NCCER tile modules and TCNA/ANSI standards. NCCER and Pearson provide the official trainee guides and module tests separately.
