Arkansas is the plainest licensing system in this family: a single operator licence, a training period served in a working boiler room, an examination given by the state itself, and an annual renewal that costs less than the first licence. This guide walks the whole of it — the attendance law that creates the need for licensed operators, the training routes the rule recognises, the examination’s form and passing grade, and the licence types the application offers — from the primary texts: Arkansas Code section 20-23-404 and the Boiler Inspection Section rules at 20 CAR Part 880.
The regulator and the law behind the licence
The Boiler Inspection Section sits inside the Arkansas Department of Labor and Licensing, and its remit is the whole boiler lifecycle the legislature delegated to it: manufacture, repair, installation, operation, and inspection of steam boilers, hot water heating and supply boilers, pressure piping, and unfired pressure vessels, together with the licensing of boiler manufacturers, sellers, repairers, operators, and inspectors. The operator licence is one instrument in that system, and it is written to interlock with the section’s other instrument — the inspection certificate that must be posted in the boiler room.
The operator rule itself is short enough to quote in substance. Rule 20 CAR 880-413 provides that boiler operators shall be licensed by the section; that an applicant shall have the prescribed training, confirmed by the employer; that the applicant shall pass an examination administered by the section, in writing or orally, scoring seventy percent; and that the applicant shall pay twenty-five dollars for examination and licensing, renewing annually at seventeen dollars. Everything else in this guide is the working-out of those four sentences.
The licence types on the application — in full
Arkansas does not publish a grade ladder. The differentiation the candidate meets is the licence type marked on the application form — high pressure, low pressure, or restricted — together with the attendance category of the plant: constant, regular, or periodic attendance as the rules define them for the boiler’s controls and alarms.
High Pressure
The high-pressure type is for operators of boilers generating steam or vapor above fifteen pounds per square inch gauge — the state’s own definitional line in 20 CAR 880-102. These are the power boilers at the centre of the attendance rules: a manual high-pressure boiler is maintained by constant attendance, one fitted with the adopted CSD-1 local alarms and safety devices by regular attendance, and one additionally fitted with remotely actuated alarms for low water, high pressure, high water, and loss of the operating boiler may move to periodic attendance with the prior approval of the Chief Inspector. The examination for this type tests the operator against that responsibility: firing, feedwater, low-water protection, and the judgment to take a boiler off line.
High-temperature, high-pressure water boilers fall under the same attendance guidelines as high-pressure steam boilers under the rule, so a candidate whose plant runs hot-water generators at pressure should expect the examination conversation — written or oral — to reach them as well.
Low Pressure
The low-pressure type covers steam or vapor boilers at or below fifteen psig, together with the hot water heating and hot water supply boilers the definitions separate out. Low-pressure plant is not unregulated plant: the rules require these boilers to meet the adopted CSD-1 requirements for controls, local alarms, and safety devices, and a steam boiler of fifty horsepower or more needs regular attendance by a licensed operator whatever its pressure class. The school, hotel, and office-building boilers named in the attendance rule are most often low-pressure heating boilers, and they are exactly the boilers whose operators sit this examination.
Because so much low-pressure plant sits in occupied buildings, the low-pressure examination candidate should expect the safety-device side of the outline — relief valves, low-water cutoffs, operating controls — to carry weight out of proportion to the plant’s size.
Restricted
The application’s third box is the restricted type. The application form offers it alongside high and low pressure without the rules publishing a separate syllabus for it in the operator-licensing rule; it is the section’s instrument for scoping a licence to a narrower duty than the general types. A candidate whose employer marks the restricted box should confirm the scope directly with the Boiler Inspection Section before examination day, because the restriction — not the examination alone — defines what the issued licence will cover.
No separate restricted-type examination format is published in 20 CAR 880-413, and this guide does not invent one: the same rule governs every applicant — training, examination, seventy percent.
Eligibility and experience, in full
Eligibility is experiential, and it is certified by the employer rather than the candidate. The standard route is six months of training under the supervision of a licensed boiler operator. The accelerated route pairs three months of that supervised training with successful completion of a boiler training program the department has approved. Either way, the training must be confirmed by the applicant’s employer and submitted to the section with the application — the section does not examine candidates whose supervised time it cannot verify.
The application form itself carries the structure: the candidate marks one licence type — High Pressure, Low Pressure, or Restricted — and records boiler operating experience, with the employer certifying that the applicant has had the training necessary to participate in the examination. The form’s own note states the philosophy plainly: the training of any boiler operator remains the sole responsibility of the employer, and issuance of a licence indicates that the applicant has passed a general examination pertaining to the operation of boilers.
The examination in detail
The examination is administered by the Boiler Inspection Section — there is no outside testing vendor in the Arkansas route — and the rule gives the section the choice of form: the examination may be in writing or may be administered orally. No question count, time limit, or content outline is published in the rule, and none is stated here; what the rule fixes is the standard, seventy percent, applied to every applicant.
That combination — state-administered, form at the section’s discretion, standard fixed in rule — shapes sensible preparation. A candidate prepares for the knowledge, not for a format: the definitions that classify the plant (high pressure above fifteen psig, low pressure at or below it, boiler horsepower as the evaporation of thirty-four and one-half pounds of water per hour from and at two hundred twelve degrees), the attendance categories and when each applies, the CSD-1 controls and alarms framework the rules adopt, feedwater and low-water protection, firing and blowdown practice, and the operator’s duties when a boiler must come off line. An oral examination rewards exactly the same command, spoken instead of written.
Applying, scheduling, and fees
Application runs through the Boiler Inspection Section on the section’s boiler operator licence application, with the twenty-five dollar payment submitted with the application; the fee covers the examination and the first licence together. The employer certification of training travels with the application — an application without it is incomplete on the rule’s own terms, because the training confirmation is a stated element of eligibility.
Scheduling is the section’s: examinations are administered by the section rather than at commercial test centres, and candidates take the date the section sets once the application — training confirmation included — is in order. The licence, once issued, renews annually at seventeen dollars.
Renewal and standing obligations
Renewal is annual and costs seventeen dollars. There is no continuing-education requirement published in the operator rule, and none is claimed here; the standing obligations are the licence itself kept current and the attendance duties it authorizes performed to the rule — the inspection certificate and the operator’s licence belong displayed in or near the boiler room, as the section’s guidance directs.
Lapses matter operationally rather than academically: an operator whose licence has lapsed is not a licensed operator for attendance purposes, and a plant that requires regular or constant attendance cannot count that person toward its legal staffing until the licence is restored.
Licences from other jurisdictions
The operator rule publishes no reciprocity or endorsement route for operators licensed elsewhere, and this guide claims none. The rule’s structure — Arkansas training confirmed by an Arkansas employer, an examination administered by the section — is the route for every applicant the rule describes. An operator arriving from another state should expect to document training and sit the section’s examination, and should confirm any individual circumstance directly with the Boiler Inspection Section.
A study plan built to this examination
Build the study plan on the rulebook the examination serves. Start with the definitions in 20 CAR 880-102, because classification questions — high pressure against low, horsepower, the attendance a given boiler requires — are decided there. Move to the attendance rule at 880-707 and work it as scenarios: for each boiler in your own plant, state its attendance category and what would change it — automatic controls, CSD-1 alarms, remote alarm approval.
Then work the operating core the examination’s purpose implies: feedwater and water-level control, low-water cutoffs and their testing, safety and relief valves, firing practice for your plant’s fuel, blowdown, and the response sequence for the failures the attendance law exists to prevent. Close with the licensing rule itself at 880-413 — training, examination, fees, renewal — so the administrative facts are as firm as the technical ones.
Examination day
Examination day in Arkansas is a state appointment, not a test-centre visit: the candidate presents to the Boiler Inspection Section arrangement with the application already approved and the employer’s training confirmation on file. Because the section may administer the examination orally, the candidate who has only ever recognised answers on paper should rehearse speaking the core procedures aloud — the low-water response, the blowdown sequence, the attendance category of each boiler in the home plant and why.
Seventy percent is the line, applied to the sitting as a whole. The result the section records becomes the licence when the fee side is complete — and in Arkansas the fee side was completed with the application, the twenty-five dollars having covered examination and licensing together.
Worked examples: attendance in real Arkansas plants
A hospital boiler room running two steam boilers of sixty horsepower each is the attendance rule in miniature. Each boiler is at or over the fifty-horsepower line, and the occupancy is one the rule names outright, so the plant sits under regular attendance by a licensed operator as a matter of law, not of the hospital’s preference. If those boilers lack fully automatic controls, the duty hardens: a full-time licensed operator while the boiler is in service. The candidate who will work that room should be able to run this analysis for any plant description — horsepower first, occupancy second, controls third — because that is the order the rule itself applies.
A school-district heating plant tells the low-pressure half of the same story. Its boilers may never exceed fifteen psig, which makes them low-pressure under the definitions, but the school occupancy is named in the rule and the boilers are the building’s only heat in January: regular attendance by a licensed operator is the district’s legal staffing floor, and the low-pressure licence type on the application form is the credential that fills it. Operators who assume low pressure means low obligation misread Arkansas law in the way the examination is positioned to catch.
The manually fired boiler is the third case, and the simplest: constant attendance when fired, says the rule — the operator present, not periodic, not regular. Between the three cases the system’s logic is visible. Attendance in Arkansas is a sliding duty set by the boiler’s size, its building, and its controls, and the licensed operator is the person the state holds to whichever setting the plant’s facts select. The candidate’s own plant is the best study text: classify it under 880-707, state its attendance category and what change of controls would move it, and the rule stops being abstract.
A final example belongs to the examination room itself. A candidate with four months of supervised training and a completed department-approved boiler training program is not yet eligible: the accelerated route pairs three months of supervised training with the approved program, so four months plus the program qualifies — while four months without the program does not, and the program without any supervised months does not either. The routes are conjunctions, not menus, and the employer’s confirmation must match the route claimed. Reading eligibility rules at that level of care is, in the end, most of what a licensing examination anywhere is testing.
One more Arkansas setting deserves its own paragraph because it is so easily misread from the road: the small plant standing alone — a food-processing boiler, a laundry, a feed mill — at forty horsepower, below the fifty-horsepower regular-attendance line. It is tempting to conclude the plant needs no licensed operator at all. The rule answers otherwise for power boilers: all power boilers subject to the boiler law are to be under attendance by a licensed operator whenever they are in use, and the fifty-horsepower sentence adds the regular-attendance duty rather than creating the licence duty. The licensed operator of that forty-horsepower plant holds the same licence, earned by the same training and the same examination at the same seventy percent, as the operator of the hospital plant across town. Arkansas’s single-licence design means there is no lesser credential to reach for in the small plant’s case — which is precisely why the section examines its operators as operators, full stop.
That uniformity has a quiet consequence for study: there is no Arkansas syllabus for a smaller licence to retreat to, and no larger one to defer to. The candidate prepares for the whole of the operator’s duty as the rules state it — every attendance category, every definition, every safety device the adopted framework names — because the licence the examination guards is, in every plant in the state, the same licence.
What the PassProfessor program will cover
Practice in the examination’s own shape. The Arkansas examination is administered by the Boiler Inspection Section in writing or orally, and the program in the works practises for the written form: single-best-answer items and timed sets built around the state’s own rules — the attendance categories, the pressure definitions, and the safety-device framework — so that a candidate who meets a written sitting has already worked at its pace and in its terms.
Written from the primary sources. The program is written from 20 CAR Part 880 — the operator rule at 880-413, the attendance rule at 880-707, and the definitions at 880-102 — and from Arkansas Code section 20-23-404, the same texts the section administers. Where Arkansas practice differs from the graded systems of other states, and on its single-licence structure it does, the program teaches the Arkansas rule and names the difference.
The whole candidate, not only the test-taker. Around the item practice, the program carries the Boiler Inspection Section route as the authority publishes it — eligibility training, the section’s examination, the seventy percent standard, and annual renewal — because a written examination is a means to a licence, and candidates plan better when the destination is mapped.
Preparation only. This is preparation for an examination administered by the Boiler Inspection Section of the Arkansas Department of Labor and Licensing. PassProfessor is not affiliated with the Department, no completion of this program is reported to the Section, and nothing in the program substitutes for the supervised training the rule requires or for any step in the licensing process.

Frequently asked questions
What statute authorizes the Arkansas boiler operator licence?
Arkansas Code section 20-23-404, with the licensing rule at 20 CAR 880-413 in the Boiler Inspection Section rules, 20 CAR Part 880.
Can the training period be shortened?
Yes, in one defined way: three months of training under a licensed operator together with successful completion of a department-approved boiler training program substitutes for the full six months of supervised training.
Who confirms my training?
Your employer. The rule requires the training to be confirmed by the applicant’s employer and submitted to the Boiler Inspection Section with the application.
Does Arkansas use an outside testing company?
No. The examination is administered by the Boiler Inspection Section itself, and may be in writing or administered orally.
Is there a published question count or time limit?
No. The rule publishes neither a question count nor a time limit, and this guide states none. The published standard is the seventy percent passing grade.
What is constant, regular, and periodic attendance?
The attendance categories of 20 CAR 880-707. Manual boilers require constant attendance; high-pressure boilers meeting the adopted CSD-1 alarm and safety-device recommendations require regular attendance; those additionally fitted with approved remotely actuated alarms may be granted periodic attendance with the Chief Inspector’s prior approval. Power boilers without fully automatic controls require a full-time licensed operator in service.
Which buildings does the attendance rule name?
Hospitals, hotels, schools, theatres, and office buildings are named for the regular-attendance duty on steam boilers, alongside the general fifty-horsepower threshold — and the rule adds that the list is not limited to those occupancies.
How is boiler horsepower defined in Arkansas?
As the evaporation of thirty-four and one-half pounds of water per hour from and at a feedwater temperature of two hundred twelve degrees Fahrenheit, per the definitions at 20 CAR 880-102.
What does the twenty-five dollars cover?
Examination and licensing together — the initial fee under 20 CAR 880-413. Renewal is seventeen dollars per year.
Does Arkansas offer reciprocity for operators licensed in other states?
The operator rule publishes no reciprocity route, and none is claimed here. Confirm individual circumstances with the Boiler Inspection Section.
What is the restricted licence type?
One of the three licence types marked on the application form, alongside high pressure and low pressure. The licensing rule does not publish a separate syllabus for it; its scope is set by the section, and candidates should confirm that scope with the section before examination.
How long is the licence valid?
One year. Arkansas operator licences renew annually at seventeen dollars.
Does renewal require continuing education?
No continuing-education requirement is published in the operator rule, and none is stated in this guide.
Can this program take the place of my six months of training?
No. The supervised training, confirmed by the employer, is a licensing requirement. This program prepares candidates for the written examination; it does not supply, shorten, or certify training.
