Arkansas licenses Journeyman Plumbers through board-administered examinations, within a tiered system that also includes Master Plumber and Restricted tiers. The code adopted in Arkansas is the Arkansas Plumbing Code, based on the 2018 International Plumbing Code. The PassProfessor Arkansas Journeyman Plumber program prepares candidates for the journeyman level of that Arkansas system and for work under the adopted Arkansas code.

What this credential certifies
An Arkansas Journeyman Plumber is a licensed tradesperson qualified to install, alter, and repair plumbing systems under Arkansas law and under the Arkansas Plumbing Code. The journeyman credential sits in the middle of a tiered structure. Below and beside it sit restricted forms of licensure for narrower scopes of work, and above it sits the Master Plumber tier, which carries the broader responsibility that Arkansas attaches to the master level. That ladder matters to how a candidate should read the journeyman examination: Arkansas does not examine the journeyman as a helper, and it does not examine the journeyman as a master. It examines a tradesperson who will do the work directly — laying out drainage, venting, and water distribution, setting fixtures, testing systems, and reading the adopted code accurately enough to install to it without supervision of every joint and fitting.
The Arkansas delta begins with administration. Examinations in this system are board-administered — given through the board structure that governs Arkansas plumbing licensure, rather than handed to a national testing vendor. Candidates therefore deal with the board’s own application, scheduling, and examination channels from first filing through result. The authoritative word on eligibility and on how a sitting is conducted comes from the board itself, and preparation must keep board administration — not a vendor’s generic process — at the centre of its Arkansas route description.

The adopted code: the Arkansas Plumbing Code
Arkansas works to a named state code: the Arkansas Plumbing Code, based on the 2018 International Plumbing Code. For the working plumber, that adoption is the daily reference — the book carried to inspections, consulted on drainage sizing, vent distances, water supply calculations, and fixture requirements across the state. For the candidate, it is the foundation on which Arkansas preparation must be built, because competence at the journeyman level in Arkansas means competence in that adopted code as Arkansas uses it: its drainage and venting rules, its water supply and distribution requirements, its standards for materials, joints, traps, and fixtures, and its provisions for testing and inspection.
PassProfessor builds the Arkansas program on that adopted-code foundation. The program teaches the code as a working system rather than as isolated rules — how a drainage sizing decision affects a venting decision, how fixture units accumulate through a building drain, and how water supply sizing protects pressure at the farthest fixture. A candidate who understands why the code requires what it requires retains the detail far longer than a candidate who has only memorised tables.
One point of discipline belongs here. This page describes the code Arkansas has adopted, and candidates should confirm current examination arrangements directly through board channels as they apply. Preparation built honestly on the adopted code and on board administration serves the Arkansas candidate better than preparation padded with examination figures borrowed from other states, which in Arkansas may not apply at all.
What journeyman-level work covers
Drainage systems — building drains and sewers, branches, and stacks, sized by fixture units, laid to grade, supported, and cleaned out so waste leaves the building reliably and can be maintained for the life of the system.
Venting — the protection of trap seals through vent systems that admit air, limit pressure variation in drainage piping, and connect correctly through wet venting, circuit venting, and individual venting arrangements as the adopted code permits them.
Water supply and distribution — sizing by demand, protecting pressure, controlling water hammer, and delivering hot and cold water to fixtures through correctly supported and insulated piping.
Fixtures and fixture settings — water closets, lavatories, bathtubs and showers, sinks, and speciality fixtures, installed level, sealed, supplied, and drained to code clearances and connection standards.
Traps, interceptors, and indirect waste — trap types, sizes, and distances, grease and oil interception where the work requires it, and indirect waste arrangements that protect potable water and food-handling areas from drainage contamination.
Water heaters and hot-water systems — installation, relief protection, venting where applicable, expansion control, and the safety devices that make stored hot water safe in residential and commercial settings.
Materials, joints, and testing — approved piping materials and joining methods for drainage, vent, and water systems, and the water, air, and other tests by which finished work is proved before it is covered or placed in service.
Protection of potable water — backflow prevention, air gaps, cross-connection control, and the separation of water supply from drainage and other hazards throughout a system.
The Arkansas layer: what makes this a Arkansas examination
Three Arkansas facts give this program its shape, and generic national material gets at least two of them wrong or vague. First, administration is board administration. Arkansas plumbing examinations are board-administered, so the candidate’s obligations — application, eligibility confirmation, scheduling, conduct at the sitting, and the handling of results — run through the board. Material written around a national vendor’s registration portal, test-centre network, or candidate bulletin does not describe the Arkansas route, however polished it looks. Second, the adopted code is identified and dated: the Arkansas Plumbing Code based on the 2018 International Plumbing Code. A candidate studying a later model-code edition as the Arkansas standard is studying the wrong book for Arkansas work, because inspectors in Arkansas inspect to the code Arkansas adopted. Third, the tier structure is Arkansas’s own: Journeyman Plumber and Master Plumber, with Restricted tiers alongside them. The restricted tiers are not a lesser journeyman licence and the master tier is not simply a journeyman with seniority; each tier carries its own scope, and the journeyman candidate should understand where the journeyman scope ends — at the work the restricted tiers narrow and at the responsibility the master tier adds.
Arkansas work gives that code structure local weight. In smaller towns and rural work a journeyman may be the most senior licensed plumber on a job, and a system must be right at installation because a return visit is measured in hours on the road. Freeze protection, reliable water service sizing, and drainage that performs in heavy rainfall are not examination abstractions in Arkansas; they are the ordinary conditions the adopted code governs.
The tiers, and where journeyman sits
The Master Plumber tier stands above the journeyman tier as the level of broader responsibility in Arkansas plumbing — the tier associated with taking responsibility for work at the business and system level. The Journeyman Plumber tier is the working credential: the licensed tradesperson who installs and repairs systems, reads drawings and the adopted code, sizes and lays out piping, and proves finished work by test. The Restricted tiers serve narrower, defined scopes within Arkansas licensure; a candidate whose intended work falls inside a restricted scope should confirm the tier that matches that work with the board before applying, while a candidate seeking the full journeyman scope should prepare for the journeyman examination itself and not assume a restricted credential will stretch to cover journeyman work. Understanding that map before applying saves a candidate from the most avoidable Arkansas error: preparing thoroughly for the wrong tier.
The route, in order
The Arkansas route runs through the board. Confirm that the journeyman tier matches the work intended, and confirm eligibility through board channels. Apply through the board’s application process. Sit the board-administered journeyman examination. On passing, receive licensure at the journeyman tier and work under the Arkansas Plumbing Code. Candidates who do not pass follow the board’s directions for any further sitting. At every step the board is the source of current requirements, forms, and directions; this program prepares candidates for the knowledge the examination examines, and directs them to the board for the administrative facts only the board can state for their own application. The companion Arkansas Journeyman Plumber Exam Guide at /arkansas-journeyman-plumber-exam-guide/ walks through that route and the adopted code in fuller detail.
Working as a journeyman in Arkansas
Licensure is the start of the obligation, not the end of it. An Arkansas Journeyman Plumber works to the Arkansas Plumbing Code on every installation, submits work to inspection where inspection is required, protects potable water on every cross-connection decision, and keeps the distinction between journeyman scope and master responsibility clear on every job. The habits the examination rewards — careful code reading and honest testing — are the same habits that carry a journeyman’s reputation across Arkansas.
What makes this examination demanding
A board-administered examination in a tiered system is demanding in a particular way: it examines the candidate the board itself will license, for work under the code the state itself adopted. There is no generic national syllabus to substitute for Arkansas knowledge. Candidates must size drainage and water systems rather than merely recognise fittings, must reason through venting rather than recite a definition, and must hold the tier structure clearly enough to know what journeyman work is. The sitting rewards the candidate who has worked through the Arkansas Plumbing Code as a system, in Arkansas terms, rather than skimming national summaries written for no state in particular.
What the PassProfessor program will cover
Built on the platform architecture: a national core plus an Arkansas delta. PassProfessor trades programs in our catalog are composed in two layers. The first is the national plumbing core — original practice material written to the drainage, venting, water supply, fixture, and safety fundamentals every journeyman system rests on. The second is the Arkansas delta: the Arkansas Plumbing Code based on the 2018 International Plumbing Code as the adopted standard for Arkansas work, board administration as the examination route, and the Journeyman, Master, and Restricted tier structure as the map of Arkansas licensure. Every item is written from scratch against primary sources; no item is drawn from another provider’s material.
Adopted-code accuracy as the teaching method. Because Arkansas candidates will be inspected to the Arkansas Plumbing Code in the field, the program teaches candidates to locate requirements in that adopted code — sizing tables, vent distances, fixture clearances, protection provisions — and to work an installation forward from the code rather than backward from habit.
Independence, stated plainly. PassProfessor is an independent preparation provider, not affiliated with the Arkansas plumbing licensing board, and this program is not a board course. Completing it confers no licence and no exemption; the board alone licenses, and candidates apply and sit through board channels.
