Exam Details

The Oklahoma Limited Residential Journeyman (Mechanical) examination contains 40 questions. Candidates are allowed 100 minutes to complete the exam. The passing score is 70%, which corresponds to 28 correct answers.

The examination covers residential mechanical knowledge across several subject areas. The current content outline includes:

• Duct Systems: 10 questions
• Vents: 4 questions
• Insulation: 3 questions
• Clothes Dryer: 3 questions
• Range Hoods: 1 question
• Clearances: 3 questions
• Access: 4 questions
• Appliance Installation: 1 question
• Restroom Exhaust Systems: 1 question
• Combustion Air: 3 questions
• Piping: 1 question
• General Installation: 3 questions
• SMACNA Symbols: 3 questions

Duct systems represent the largest portion of the examination, but candidates should prepare across the entire outline. Questions can require knowledge of residential mechanical installations as well as the ability to find information within the approved references.

With 40 questions and 100 minutes available, exam preparation should include timed practice. Candidates who are accustomed to navigating their books may be better positioned to locate information without spending unnecessary time searching through unfamiliar sections.

Open Book Test

The Oklahoma Limited Residential Journeyman Mechanical examination is an open-book test. Approved references may be brought into the examination center and used during the testing session.

Reference materials may be highlighted, underlined, and indexed before the examination. Permanent tabs are permitted. Temporary tabs such as Post-it notes are not permitted. References may not contain written notes, and candidates may not write in the references before or during the examination session.

This makes preparation with properly organized books particularly valuable. An open-book exam does not eliminate the need to study. Candidates still need to understand the mechanical concepts being tested and know which reference is most likely to contain the information needed for a question.

Spend time working with the highlighted and tabbed books before test day. Practice finding requirements related to duct systems, ventilation, insulation, appliance installation, combustion air, dryer exhaust, clearances, access, piping, and other residential mechanical subjects. Familiarity with the layout of the references can help make the open-book format easier to manage.

Licensing Steps

1. Complete qualifying mechanical training and experience. Oklahoma journeyman applicants must meet the experience or approved education-and-experience requirements for the mechanical classification being pursued.
2. Submit the mechanical journeyman license application. The application is handled through the Oklahoma Construction Industries Board.
3. Receive approval for examination. Examination eligibility must be approved before the candidate can proceed with scheduling.
4. Schedule the required examination. Approved candidates receive information for arranging the date, time, and testing location through the examination provider.
5. Prepare for the Limited Residential Journeyman Mechanical exam. Review the exam topics and become familiar with the permitted reference materials.
6. Take the examination. Candidates must achieve the required passing score for the Limited Residential Journeyman Mechanical examination.
7. Complete applicable licensing requirements. Candidates must satisfy the Oklahoma Construction Industries Board requirements associated with issuance of the license.

State Requirements

Applicants for an Oklahoma mechanical journeyman license must be at least 18 years of age and meet the state's qualifying experience requirements.

One qualifying pathway is three years of verifiable experience in the mechanical trade in the category for which the applicant is applying. Oklahoma also recognizes specific combinations of approved mechanical education and verifiable trade experience.

Approved education pathways can reduce the amount of required field experience depending on the number of instructional hours completed. The state also recognizes qualifying equivalent mechanical experience gained while serving in the U.S. military and certain current out-of-state mechanical licenses that meet applicable requirements.

For licensing purposes, one year of verifiable mechanical experience is defined as 2,000 hours. Applicants who are not licensed and want Oklahoma mechanical work experience counted toward examination qualification are required to maintain the applicable apprentice registration for that experience.

The Limited Residential Journeyman classification has a specific scope. It covers installation of complete new systems for detached one- or two-family dwellings and multiple single-family dwellings such as townhouses that are not more than three stories in height and have a separate means of egress.

The classification includes cooling systems of 5 tons or less and heating systems of 150,000 Btu/h or less, along with related accessories such as humidifiers, filtering systems, kitchen vent hoods, exhaust fans, and clothes dryer vent exhausts for qualifying dwellings.

The classification does not include fuel-gas piping, welding, soldering, brazing, final connection of refrigerant lines, or final connection of electrical wiring permitted to be installed under Oklahoma law.

Reference Books

• Included Book: International Residential Code for One- and Two-Family Dwellings, 2018
  This residential code reference contains requirements affecting one- and two-family dwellings, including provisions relevant to mechanical systems, equipment, ductwork, ventilation, exhaust, combustion air, clearances, and installation. The exam is based on the listed 2018 code edition for applicable code questions.
• Included Book: Oklahoma Mechanical Industry Regulations, Oklahoma Administrative Code, Title 158, Chapter 50
  This Oklahoma-specific reference addresses mechanical industry regulations associated with licensing, classifications, experience, responsibilities, and mechanical work regulated within the state. Becoming familiar with Oklahoma requirements is an important part of preparing for a state licensing examination.
• Included Reference: SMACNA Symbols Sheet
  The SMACNA Symbols Sheet provides mechanical and sheet metal symbols that candidates should recognize for the examination. SMACNA symbols are specifically included in the Limited Residential Journeyman Mechanical exam content outline.

The included books are highlighted and tabbed to help candidates quickly identify important material and navigate major sections. Candidates should still spend time practicing with the books so the tabs and highlighted areas become familiar before the examination.

Test Information and Study Materials

Effective preparation for the Oklahoma Limited Residential Journeyman Mechanical exam should combine trade knowledge, code review, and repeated reference navigation. Start by learning the structure of each included reference. Identify the table of contents, major chapters, definitions, important tables, and sections that correspond with the examination outline.

Because duct systems account for 10 questions, give substantial study time to duct-related requirements. Review installation practices, sizing concepts, supports, materials, clearances, and other applicable residential duct provisions.

Ventilation is another important area. Candidates should be familiar with requirements affecting vents, restroom exhaust systems, range hoods, dryer exhaust systems, and related residential mechanical installations.

Combustion air, insulation, equipment clearances, and access requirements should also receive focused attention. These subjects often require candidates to understand both the mechanical concept and the location of the applicable code requirement.

Practice using the SMACNA Symbols Sheet rather than simply looking at it once before the exam. Learn to recognize the symbols and understand how they may be used to communicate mechanical information.

Timed practice is valuable because the examination provides 100 minutes for 40 questions. That averages approximately two and a half minutes per question. Some questions may be answered quickly from trade knowledge, while others may require reference research. Developing an efficient approach can help preserve time for questions that require more detailed code navigation.

When practicing, avoid turning every question into a lengthy research exercise. First determine whether you know the answer. If a reference is needed, identify which book is most likely to contain the information and use the tabs to move directly to the relevant area.

The more frequently you use the same highlighted and tabbed references, the more familiar their organization becomes. This familiarity can make study sessions more productive and help reduce time spent searching for information.
