The New York City High Pressure Boiler Operating Engineer License, issued by the Department of Buildings, is earned through a written examination and a practical examination: 110 closed-book multiple-choice questions in four hours, delivered at Pearson VUE, passed at 77 correct answers. Preparation in this program covers the written examination only – its four domains, from Administration to Repairs and Alterations, its code references across Title 28 and the Mechanical Code, and the experience-route documentation the Department requires before a candidate may sit.

One city, one license – and a scope statement that matters
New York runs the most instructive exception in American boiler licensing: the State licenses no boiler operators at all, and the City licenses its high-pressure operators to one of the highest standards in the country. The High Pressure Boiler Operating Engineer License, issued by the New York City Department of Buildings under Title 28 of the Administrative Code, authorises its holder to operate and supervise high-pressure boiler plant across the five boroughs – stationary plant and portable plant alike.
The scope statement comes first, because honesty about it is this program’s foundation: the license has two examinations, a written examination and a practical examination, and this program prepares candidates for the written examination only. The practical – fifteen exercises performed before examiners – cannot be prepared for in a written program, and no page in this package pretends otherwise. What the written examination demands is large enough: 110 closed-book questions in four hours, passed at 77 correct answers, spanning the operating, inspection, repair, and administrative law of the City’s boiler code.

The seven roads in
The Department’s guide publishes seven experience routes, and they share a signature: nearly all of them require time inside New York City, under the City’s own licensees, inside the last seven years. The standard road is five years within the last seven working under a Department-licensed high pressure boiler operating engineer in the City. The credentialed roads shorten the City time and lengthen the paper: a bachelor’s degree in mechanical engineering plus one year of City experience within the last two; an engineer certificate or a U.S. Coast Guard marine engineer certificate held four years plus one City year; a National Board commission held seven years plus five years of high-pressure experience within the last seven.
Two roads serve candidates formed outside the boiler room’s usual ladder: five years in direct supervision of a governmental building steam plant whose boilers are at least 150 horsepower, plus one City year; and a registered approved apprenticeship of at least two years plus three years of experience within the last seven. The seventh road imports experience: a high-pressure operating engineer license or certification from another jurisdiction that uses ASME codes, held five years, with employment during five of the last seven. Around the routes stand the personal qualifications: 18 or older, able to read and write the English language, of good moral character, and fit to perform the work.
The written examination
CPS HR Consulting administers the Department’s licensing examinations, and the written examination is delivered at Pearson VUE testing locations. Its structure, from the Department’s candidate bulletin: 110 multiple-choice questions, closed book, four hours, with a passing score of 77 – seventy percent of the paper. The outline divides the paper into four domains. Administration takes 22 questions. Inspection and Testing takes 33. Operation and Maintenance takes 33. Repairs and Alterations takes 22.
The reference list published with the examination tells the candidate what the paper is made of: Title 28 of the Administrative Code; Chapters 10 and 12 of the New York City Mechanical Code; Rules of the City of New York sections on boiler inspections, annual filings, and related duties; the State Department of Labor’s Part 14 high-pressure boiler rules, which the City’s plant also answers to; and the field’s standard texts on steam plant operation and high-pressure boilers. A candidate is permitted scratch paper and, under the bulletin’s terms, a silent non-programmable calculator. The result arrives by mail and can be requested by email, and the pass notice starts two clocks, described below.
The practical examination: context, not coverage
The practical examination is a Department requirement and a real second gate: fifteen exercises in ninety minutes, scored at 70 percent, with designated critical exercises the candidate must pass outright. Candidates apply for it within two months after passing the written examination, and must pass it within twenty-four months of the written pass notification. This program does not prepare candidates for it, and this page’s treatment of it is context only – its existence, its deadlines, and its weight in planning. A candidate who passes the written and neglects the practical clocks loses the written result with them; the route discipline below exists to prevent exactly that.
Sequence, deadlines, and fees
The route runs on clocks. Apply for the written examination; once the application is approved, the examination must be taken within six months. Pass it, and the practical application is due within two months of the pass, with the practical itself passed within twenty-four months of the notification. The Department’s fees are paid by money order only: $525 for the written examination and $350 for the practical, with background investigation and license issuance fees separate and additional – the Department’s background investigation is a real step in this licensure, reflecting the access a licensed engineer holds to the plant of occupied buildings.
The license, once issued, renews every three years. Candidates budgeting the route should hold the whole fee picture – two examinations, investigation, issuance, and triennial renewal – rather than the written fee alone.
Who holds this license
The New York City high-pressure engineer runs the plant of the densest vertical city in the country: hospital and university power plants, office-tower boiler rooms, hotel and residential high-rise plant, municipal buildings, and the district plant of institutions that cannot tolerate a cold morning. The license’s portable scope adds the temporary and construction plant the City’s building churn requires. It is, by the design of its routes, a license earned largely inside the City’s own boiler rooms, under its own licensees – a guild structure administered by a modern buildings department, which is why its holders are known quantities to the building community that employs them.
The difficulty, honestly stated
Four hours and 110 closed-book questions is the largest written sitting among city operator licenses, and its outline refuses narrowness: a fifth of the paper is administration – filings, inspections, duties, the paper trail of a regulated plant – which hands-on operators chronically under-prepare. The 77-answer line punishes domain imbalance: inspection and operation together are sixty percent of the paper, so a candidate strong in one and weak in the other sits exactly at the margin. And the written is only the first gate; the wise candidate treats the written preparation and the practical preparation as one campaign with two fronts, arranged so the practical’s clocks are met with margin.
What the PassProfessor program will cover
The written examination, and only the written examination. This program prepares candidates for the Department’s written examination – 110 closed-book multiple-choice questions in four hours across Administration, Inspection and Testing, Operation and Maintenance, and Repairs and Alterations, passed at 77. It does not prepare candidates for the practical examination, and it says so wherever the license is described.
Practice in the examination’s own shape. Closed-book, timed sets weighted to the published outline, with the Administration domain given its full fifth of the weight – the allocation candidates most often get wrong when they prepare from operating experience alone.
Written from the primary sources. The program is written from the Department of Buildings’ license guide and candidate bulletin, Title 28, the Mechanical Code chapters the bulletin names, the cited City rules, and the State’s Part 14 boiler rules – the examination’s own reference list, used as the syllabus it is published to be.
The route beside the items. The seven experience routes, the application and appeal mechanics, the money-order fees, and the written-to-practical clocks are carried as route material, because this license loses more candidates to sequence errors than most systems lose to questions.
Preparation only. This is preparation for an examination administered for the New York City Department of Buildings. PassProfessor is not affiliated with the Department of Buildings, CPS HR Consulting, or Pearson VUE, and no completion of this program is reported to the Department.
