New Mexico certifies boiler operators through the Construction Industries Division on two interlocking tracks: a boiler operator certificate of competence with Trainee, Low Pressure, and High Pressure classifications under 14.9.4.29 NMAC, each examined after six months of plant experience, and journeyman boiler operator certificates – BO1 for low pressure only and BO2 for low and high pressure – under 14.6.4.8 NMAC, passed at 75 percent. This program prepares candidates for the written examinations on both tracks.

Two tracks, one boiler room
New Mexico does not run its boiler operator certification through a single license, and candidates who arrive expecting one discover the system’s actual shape: two tracks that meet in the same boiler room. The first track sits in the boiler rules themselves. Under 14.9.4.29 NMAC, the Mechanical Bureau of the Construction Industries Division classifies boiler operators as Trainee, Low Pressure, and High Pressure, and issues an operator certificate of competency under Section 60-13-38 of the Construction Industries Licensing Act. The second track sits in the journeyman certification rules: under 14.6.4.8 NMAC, the Division certifies journeyman boiler operators in two classifications, BO1 for low pressure only and BO2 for low and high pressure, inside the same journeyman framework that certifies the State’s electricians, plumbers, and pipe fitters.
The tracks are not rivals. The boiler-rule classifications describe the operator’s authority over plant types, in the language of the boiler code. The journeyman certificates describe the operator’s standing in the State’s construction-industries licensing system, with its own examination procedure and its own passing score. A candidate’s employer, plant, and ambitions decide which track – or both – the candidate needs, and this program is built to prepare candidates for the examinations on either.

The pressure line that organises everything
New Mexico draws its operator world along one number: 15 psi. Under the definitions at 14.9.4.7 NMAC, a high pressure steam boiler is a boiler in which steam or other vapor is generated at pressures exceeding 15 psi, and a high temperature water boiler works above 160 psi or 250 degrees F. The Low Pressure operator classification reaches steam boilers and direct-fired pressure vessels up to 15 psi, and hot water boilers up to 160 psi and 250 degrees F. The High Pressure classification reaches high-pressure boilers at 15 psi and greater, together with everything the Low Pressure classification covers. The same line divides the journeyman certificates: BO1 is low pressure only, BO2 is low and high pressure. Every New Mexico candidate should fix that line first, because it decides which examination is the candidate’s examination.
The classifications, one by one
Boiler operator trainee
The entry classification, and the only one that carries no examination and no certificate: 14.9.4.29 provides that no State certificate of competence is required for a boiler operator trainee. The trainee is an entry-level position with one hard limitation – the trainee shall not operate any devices except under the direct observation of a boiler operator. The trainee months are therefore supervised months by design, and they are the natural source of the experience the examined classifications require.
Boiler operator – Low Pressure
Six months of operating experience on the type of plant to be licensed on, and a pass on the low pressure examination. The authority that follows is the heating-plant world: steam boilers and direct-fired pressure vessels up to 15 psi, and hot water boilers up to 160 psi and 250 degrees F – the boilers of schools, hospitals, hotels, and commercial buildings across the State.
Boiler operator – High Pressure
At least six months of verifiable operating experience on the type of plant to be licensed on, and a pass on the prescribed examination. The authority covers high-pressure boilers at 15 psi and greater, and carries the whole Low Pressure scope with it. The word verifiable does real work in this rule: the experience must be capable of being checked, which rewards candidates who keep records of plant, equipment, and duties from the start of their six months.
Journeyman boiler operator – BO1 and BO2
The journeyman track restates the same divide in the construction-industries register. BO1 is low pressure only; BO2 is low and high pressure. Each requires six months of experience, and each carries the journeyman system’s two defining limits: the holder can be employed by an institution that has a boiler, and cannot perform construction or repair of a boiler. These are operator certificates, in other words, not mechanical contractor credentials – they authorise running plant, not building or mending it.
What the examinations cover
The statute frames the examination’s double character at Section 60-13-38 NMSA 1978: the applicant is examined as to knowledge of the orders and rules governing the occupation, and as to technical knowledge and ability pertaining to the trade. The boiler rules supply the technical field the operator classifications examine: boiler definitions and classifications, inspection and certificates of inspection, safety appliances and the rule that no person works on a safety appliance under pressure, hydrostatic testing, repairs, and the operating limits written into each classification. The journeyman examination sits inside the Division’s general journeyman procedure: eligibility follows satisfactory work-experience documentation, the examination is administered by CID or its designee, and the passing score is 75 percent or higher.
One structural note belongs in plain view. The boiler rules’ own definition of a publicly owned place of public assembly states that the operator qualification and certification rules at 14.9.4.29 apply specifically to that setting – publicly owned schools, hospitals, and similar places where large numbers of people congregate. Candidates should read their own employer’s position against that text rather than assume the certificate’s reach, and this program’s route material treats the question as one to settle with the Mechanical Bureau, not as a slogan.
Who these certificates serve
The New Mexico operator is, by the rules’ own design, an institution’s person. The journeyman classifications say it outright: the BO1 and BO2 holder is employed by an institution that has a boiler. The plants are the State’s public and institutional stock – schools and universities, hospitals, courthouses and state buildings, hotels and laundries – where a boiler runs as part of a building’s life rather than as a factory’s process. The trainee-to-operator ladder fits that world: supervised entry, six months on the plant type, an examination, and a certificate whose limits (operate, do not construct or repair) match the institution’s division of labour, in which construction and repair belong to licensed mechanical contractors and their journeymen in other classifications.
The route, in order
The route runs: accumulate the six months of operating experience on the type of plant the classification covers – as a trainee under direct observation where the boiler-rule track is concerned; document it so that it can be verified; apply to the Construction Industries Division on its forms with satisfactory work-experience documentation; sit the examination for the classification – the low pressure or prescribed examination on the operator track, or the BO1 or BO2 journeyman examination administered by CID or its designee; and reach the standard the track sets, 75 percent on the journeyman side. The rules also hold a door open for candidates whose path was training rather than time: under 14.9.4.29(D), alternative methods of training may be approved by the Mechanical Bureau chief in lieu of experience, and the certificate issues on successful completion of the appropriate examination.
What makes these examinations demanding
The demand is breadth at a working level. The operator examinations sample a rulebook that runs from definitions and inspection law to safety appliances, hydrostatic tests, and repair boundaries, and they sample it for candidates whose experience is six months deep – enough to have run a plant, not enough to have met its rare events. The journeyman sitting adds the Division’s general standard: 75 percent is a higher line than many operator examinations set, and the retake rule – no more than two repeats in any 30-day period – punishes a casual attempt with a calendar. Candidates who treat either examination as a formality appended to experience tend to meet the part of the field their own plant never showed them.
The certificates at work
At work, the certificate draws the line the institution staffs to. The trainee watches and assists under direct observation. The Low Pressure operator runs the heating plant. The High Pressure operator takes the power boilers. The BO1 and BO2 journeymen stand inside the construction-industries system as certified operators whose authority stops, expressly, at construction and repair. That boundary is not a slight on the credential; it is the credential’s definition, and it protects the operator as much as the public, because work beyond the certificate is work the State assigns to other licenses.
What the PassProfessor program will cover
Practice in the examinations’ own shape. The New Mexico examinations are written certification examinations administered under the Construction Industries Division’s procedures, and the program in the works practises in that shape: written sets organised by classification – Low Pressure, High Pressure, BO1, BO2 – so a candidate studies the sitting they will actually take, at the standard the track sets.
Written from the primary sources. The program is written from the rules themselves – 14.9.4 NMAC for the boiler classifications and definitions, 14.6.4 and 14.6.6 NMAC for the journeyman certificates, and Section 60-13-38 for the examination’s statutory frame. Where the two tracks differ, and on passing score, scope, and limits they do, the program teaches each track’s own rule and names the difference.
The whole candidate, not only the test-taker. Around the item practice, the program carries the route as the Division publishes it – experience documentation, the trainee’s supervised status, the bureau-chief training alternative, and the retake limits – because candidates lose more time to route errors than to any single topic.

Frequently asked questions
What is the difference between the operator certificate and the BO1/BO2 journeyman certificates?
They are two tracks in one system. The operator certificate of competence, under 14.9.4.29 NMAC, classifies boiler operators as Trainee, Low Pressure, and High Pressure within the boiler rules. The BO1 and BO2 certificates, under 14.6.4.8 NMAC, are journeyman certificates inside the Construction Industries Division’s journeyman framework: BO1 is low pressure only, BO2 is low and high pressure. Both tracks require six months of experience and an examination.
What pressure divides low pressure from high pressure in New Mexico?
15 psi. A high pressure steam boiler generates steam or other vapor at pressures exceeding 15 psi, under the definitions at 14.9.4.7 NMAC. The Low Pressure classification covers steam boilers up to 15 psi and hot water boilers up to 160 psi and 250 degrees F; the High Pressure classification covers boilers at 15 psi and greater plus the low pressure scope.
How much experience do the New Mexico classifications require?
Six months. The Low Pressure operator needs six months of operating experience on the type of plant to be licensed on; the High Pressure operator needs at least six months of verifiable operating experience on that plant type; BO1 and BO2 each require six months of experience.
What is the passing score for the New Mexico examinations?
The journeyman rules publish the standard: 75 percent or higher, under 14.6.4.8 NMAC, on an examination administered by CID or its designee. The boiler-rule operator classifications require a pass on the low pressure or prescribed examination; that rule does not print a percentage, and this program does not invent one.
What can a trainee do?
A boiler operator trainee holds an entry-level classification, needs no State certificate of competence, and shall not operate any devices except under the direct observation of a boiler operator, under 14.9.4.29 NMAC.
Can a BO1 or BO2 holder repair boilers?
No. The journeyman classifications state that the holder can be employed by an institution that has a boiler and cannot perform construction or repair of a boiler. The certificates authorise operation, not construction or repair.
Can training substitute for the six months of experience?
On the operator track, yes, within limits: under 14.9.4.29(D) NMAC, alternative methods of training may be approved by the Mechanical Bureau chief in lieu of experience, and the certificate of competency issues on successful completion of the appropriate examination.
How often can I retake the journeyman examination?
The journeyman procedure allows an applicant who fails to take another regularly scheduled examination on reapplication and payment of the fee, but not more than twice in any 30-day period, under 14.6.4.8 NMAC.
Who administers the New Mexico examinations?
The Construction Industries Division of the Regulation and Licensing Department, through its Mechanical Bureau for the boiler rules, with journeyman examinations administered by CID or its designee, as the rules provide.
Is PassProfessor affiliated with the State of New Mexico?
No. PassProfessor is an independent preparation provider, not affiliated with the Construction Industries Division or the New Mexico Regulation and Licensing Department. The program confers no certificate and reports nothing to the Division.
