PTI Level 1 & 2 Certification Exam | Complete Practice
Questions, Correct Answers & Detailed Rationales (2026/2027)
Question 1
What is the minimum examination passing score required to be eligible
for PTI Level 2 Unbonded PT Installer or Inspector certification during a
certification workshop?
• A. 80% or higher on the final certification exam.
• B. Exactly 50% matching standard academic curves.
• C. 60% with an oral interview waiver.
• D. 95% across all practical modules.
Correct Answer: A. 80% or higher on the final certification exam.
Detailed Rationale: According to PTI field personnel certification
guidelines, candidates must achieve a score of 80% or higher on the
final exam along with meeting experience affidavits to qualify for Level
2 status.
Question 2
What total field work experience hours are typically required to obtain a
PTI Level 2 Unbonded PT Installer or Inspector certification?
• A. A total of 500 hours or more of verifiable field experience.
• B. Exactly 50 hours of workshop attendance.
• C. 2,500 hours of supervisory office work.
• D. No field experience is required if the exam score exceeds 90%.
,Correct Answer: A. A total of 500 hours or more of verifiable field
experience.
Detailed Rationale: PTI requirements specify that candidates aiming for
Level 2 certification must fulfill 500 hours of total field work experience,
split between installation/stressing or inspection.
Question 3
Which major industry codes and standards do PTI individual
certification programs comply with regarding installation and inspection
practices?
• A. International Building Code (IBC), ACI 318, and ACI 301.
• B. National Electrical Code (NEC) and ASHRAE standards.
• C. OSHA maritime regulations only.
• D. Federal Aviation Administration (FAA) runway codes.
Correct Answer: A. International Building Code (IBC), ACI 318, and ACI
301.
Detailed Rationale: PTI training programs ensure that field personnel
comply with standard model building codes and American Concrete
Institute standards governing structural concrete construction.
Question 4
How frequently must certified field personnel renew their Post-
Tensioning Institute (PTI) personnel certification?
• A. Every 4 years.
• B. Annually every January.
, • C. Every 10 years.
• D. Certification never expires once earned.
Correct Answer: A. Every 4 years.
Detailed Rationale: PTI field personnel certifications are valid for a
period of 4 years, after which personnel must complete renewal
requirements to maintain active status.
Question 5
What is the primary function of the heavy-duty plastic sheathing and
corrosion-inhibiting grease applied to unbonded single-strand post-
tensioning tendons?
• A. To provide permanent corrosion protection and allow the
strand to move freely inside the concrete without bonding.
• B. To bond the steel strand directly to the surrounding concrete
matrix.
• C. To increase the ultimate tensile strength of the steel wire by
50%.
• D. To act as an electrical conductor for grounding structural steel.
Correct Answer: A. To provide permanent corrosion protection and
allow the strand to move freely inside the concrete without bonding.
Detailed Rationale: Unbonded systems rely on continuous grease and
tight plastic sheathing to protect the strand against moisture and
chemical corrosion while facilitating uninhibited elongation during
stressing.
Question 6
, What type of steel wire is standardly used for single-strand unbonded
post-tensioning systems in North America?
• A. Seven-wire low-relaxation steel strand conforming to ASTM
A416.
• B. High-carbon solid steel rebar conforming to ASTM A615 Grade
60.
• C. Mild carbon structural steel tubing.
• D. Galvanized iron wire rope.
Correct Answer: A. Seven-wire low-relaxation steel strand conforming
to ASTM A416.
Detailed Rationale: ASTM A416 seven-wire strand provides the high
tensile strength and low stress-relaxation properties required for
effective post-tensioning applications.
Question 7
What is the primary purpose of the anchor casting (anchor head or
wedge plate) in an unbonded post-tensioning system?
• A. To transfer the stressing force from the steel tendon into the
hardened concrete structure after stressing.
• B. To anchor the electrical conduits within the slab.
• C. To connect water supply pipes to the concrete deck.
• D. To hold formwork panels in place during concrete pouring.
Correct Answer: A. To transfer the stressing force from the steel tendon
into the hardened concrete structure after stressing.
