1. Which agency is responsible for issuing the New York City High Pressure Boiler Operating
Engineer license?
A) New York City Department of Buildings
B) New York State Department of Labor
C) New York City Fire Department
D) Department of Citywide Administrative Services
Correct Answer: New York City Department of Buildings
Rationale: NYC DOB is the licensing authority identified for High Pressure Boiler Operating Engineers
in New York City. The license authorizes qualified individuals to operate applicable high-pressure
boilers within the city. Other agencies may regulate related safety, employment, or facility matters,
but they do not replace DOB as the licensing authority for this credential.
2. What examination sequence must a candidate follow to qualify for the NYC High Pressure Boiler
Operating Engineer license?
A) Practical examination followed by written examination
B) Written examination followed by practical examination
C) Background investigation followed by practical examination only
D) Written examination and practical examination simultaneously
Correct Answer: Written examination followed by practical examination
Rationale: NYC DOB requires candidates to pass the written examination before proceeding to the
practical examination. After receiving notification of passing the written examination, the candidate
applies for the practical examination. This sequence allows the candidate's fundamental regulatory
and technical knowledge to be evaluated before practical operating skills are assessed.
3. What is the published passing standard for the written High Pressure Boiler Operating Engineer
examination?
A) 65 percent
B) 68 percent
C) 70 percent
D) 75 percent
Correct Answer: 70 percent
Rationale: The published examination information establishes a 70 percent minimum passing score
for the written examination. For the 110-question examination described in the Candidate
,Information Bulletin, this corresponds to 77 correct answers. Candidates should distinguish the
official passing standard from unofficial practice-test scoring systems or commercial preparation
claims.
4. According to the published examination outline, how much time is allowed for the written
examination?
A) 2 hours
B) 3 hours
C) 3.5 hours
D) 4 hours
Correct Answer: 4 hours
Rationale: The Candidate Information Bulletin specifies four hours for the 110-question written
examination. The test is designed to evaluate knowledge of applicable NYC codes, rules, regulations,
and trade-specific boiler knowledge. Effective time management is therefore important, particularly
because the examination is closed book and requires candidates to recall applicable requirements.
5. Which statement best describes the written examination?
A) It is a closed-book multiple-choice examination.
B) It is an open-book practical examination.
C) It permits unrestricted personal reference materials.
D) It consists entirely of oral questions.
Correct Answer: It is a closed-book multiple-choice examination.
Rationale: The published CIB describes the written examination as a closed-book examination
containing multiple-choice questions. Candidates are not permitted to bring reference materials into
the testing site. This makes familiarity with applicable requirements and technical concepts especially
important because candidates cannot depend on searching printed codes during the examination.
6. Which category contains the largest number of questions in the published written examination
blueprint?
A) Administration
B) Inspection and Testing
C) Repairs and Alterations
D) General Regulations alone
Correct Answer: Inspection and Testing
Rationale: The published blueprint allocates 33 questions to Inspection and Testing, compared with
22 for Administration, 33 for Operation and Maintenance, and 22 for Repairs and Alterations. Thus,
Inspection and Testing is tied with Operation and Maintenance for the largest allocation and
represents a major examination emphasis.
7. How many questions are assigned to Administration in the published written-examination
outline?
A) 22
B) 25
, C) 30
D) 33
Correct Answer: 22
Rationale: Administration accounts for 22 questions in the published examination outline. Its
subareas include general regulations, logbooks, and tubes. These administrative subjects are not
merely paperwork topics; they connect documentation and regulatory compliance with the safe
operation and maintenance of high-pressure boiler systems.
8. How many questions are assigned to Inspection and Testing?
A) 22
B) 27
C) 30
D) 33
Correct Answer: 33
Rationale: The published blueprint assigns 33 questions to Inspection and Testing. Subtopics include
gauges, high-pressure steam piping systems, inspections, installation, maximum allowable pressure,
miniature boilers, pressure tanks, tests, tubes, and valves. This substantial allocation demonstrates
that inspection and testing knowledge is a central component of the licensing examination.
9. How many questions are assigned to Operation and Maintenance?
A) 33
B) 22
C) 28
D) 30
Correct Answer: 33
Rationale: Operation and Maintenance receives 33 questions in the published written-examination
outline. The listed subjects include expansion tanks, low-water cutoffs, maximum allowable pressure,
miniature boilers, removal of waste, tubes, valves, and water. These topics require candidates to
understand both equipment function and safe operating practices.
10. How many questions are assigned to Repairs and Alterations?
A) 18
B) 20
C) 22
D) 33
Correct Answer: 22
Rationale: Repairs and Alterations represents 22 questions in the published blueprint. Its listed
subjects include joints and connections, materials, maximum allowable pressure, piping installations,
pressure tanks, and tubes. Candidates should understand that repairs and alterations to pressure
equipment can affect safety and must comply with applicable requirements rather than being treated
as ordinary maintenance.
