CERTIFIED CERAMIC TILE INSTALLER (CTI) EXAM QUESTIONS
COMPLETE WITH VERIFIED ANSWERS




1. The CTI technical proficiency exam consists of how many multiple-
choice questions?
A. 100
B. 125
C. 155
D. 200
C. 155
Rationale: The technical proficiency exam consists of 155 multiple-
choice questions and is open-book, with candidates given four hours to
complete it.
2. Which two publications serve as the primary references for the CTI
open-book exam?
A. NTCA Reference Manual and ANSI A118
B. TCNA Handbook and CTEF Field Manual
C. ASTM C1027 and ISO 13006
D. Tile Council Product Catalog and MAPEI Installation Guide
B. TCNA Handbook and CTEF Field Manual
Rationale: The exam is based on the TCNA Handbook for Ceramic, Glass,
and Stone Tile Installation and the CTEF Field Manual for Thin-bed
Installation of Ceramic Tile, which reference ANSI standards.
3. What is the minimum passing score required for the CTI certification?
A. 70%

,B. 75%
C. 80%
D. 85%
D. 85%
Rationale: A passing grade is 85% or higher, combining the scores from
both the online knowledge exam and the hands-on practical test.
4. The CTI program is administered by which organization?
A. Tile Council of North America (TCNA)
B. American National Standards Institute (ANSI)
C. Ceramic Tile Education Foundation (CTEF)
D. National Tile Contractors Association (NTCA)
C. Ceramic Tile Education Foundation (CTEF)
Rationale: The CTI program was initiated by the Ceramic Tile Education
Foundation (CTEF) in 2008 and is the only third-party assessment of
installer skill and knowledge recognized by the tile industry.
5. Which ANSI standard governs the installation of ceramic tile with dry-
set mortars?
A. ANSI A108.1
B. ANSI A108.5
C. ANSI A118.4
D. ANSI A136.1
B. ANSI A108.5
Rationale: ANSI A108.5 covers the installation of ceramic tile with dry-
set mortars and specifies mortar coverage requirements.
6. ANSI A118.9 establishes performance requirements for which type of
substrate?

,A. Gypsum wallboard
B. Cement backer board
C. Oriented strand board (OSB)
D. Fiber-reinforced gypsum board
B. Cement backer board
Rationale: ANSI A118.9 establishes performance requirements for
cement backer boards (also called cementitious backer units or CBUs)
used as substrates for tile, covering dimensional stability, water
resistance, and bond strength.
7. Which ANSI standard covers crack isolation membranes used beneath
tile installations?
A. ANSI A118.10
B. ANSI A118.12
C. ANSI A118.4
D. ANSI A108.1
B. ANSI A118.12
Rationale: ANSI A118.12 establishes performance requirements for
crack isolation membranes, which are designed to prevent substrate
cracks from transferring through the tile.
8. ANSI A118.10 specifies requirements for which type of product?
A. Organic adhesives
B. Waterproof membranes
C. Chemical-resistant furan mortars
D. Epoxy emulsion mortars
B. Waterproof membranes
Rationale: ANSI A118.10 specifies performance requirements for load-

, bearing, bonded, waterproof membranes used in thin-set ceramic tile
and dimension stone installations.
9. Which standard covers organic adhesives for the installation of
ceramic tile?
A. ANSI A108.1
B. ANSI A118.4
C. ANSI A136.1
D. ANSI A118.10
C. ANSI A136.1
Rationale: ANSI A136.1 is the American National Standard Specifications
for Organic Adhesives for Installation of Ceramic Tile.
10. What is the minimum recommended mortar coverage for ceramic
tile installed on a wall?
A. 50%
B. 65%
C. 80%
D. 95%
B. 65%
Rationale: ANSI A108 standards recommend at least 65% coverage on
walls to ensure proper adhesion and prevent hollow spots. For exterior
and wet areas, 95% coverage is required.
11. What is the minimum mortar coverage required for large format tile
in wet areas?
A. 50%
B. 65%
C. 80%
D. 95%
