The Limited Residential Journeyman scope 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.

The Ultimate Exam Prep Rental Package is built around the three references identified for the Limited Residential Journeyman examination: the International Residential Code for One- and Two-Family Dwellings, 2018, the Oklahoma Mechanical Industry Regulations in Oklahoma Administrative Code Title 158, Chapter 50, and the SMACNA Symbols Sheet.

All included rental books are highlighted and tabbed to support organized study and faster reference navigation. Because the examination is open book, candidates should become comfortable using these references well before exam day. Course preparation should include technical review, timed practice, book navigation, and repeated use of the references to locate information efficiently.

Package Price: $895 plus a refundable $150 book deposit, for a total initial payment of $1,045.

With 100 minutes available for 40 questions, candidates have an average of approximately two and a half minutes per question. Some questions may be answered quickly through trade knowledge, while others may require candidates to locate a code provision, regulation, or symbol in one of the approved references.

Open Book Test

The Oklahoma Limited Residential Journeyman (Mechanical) examination is an open-book test. Candidates may bring the approved references identified for this examination into the testing center.

The permitted references include the International Residential Code for One- and Two-Family Dwellings, 2018 edition with Oklahoma revisions, the Oklahoma Mechanical Industry Regulations in Oklahoma Administrative Code, Title 158, Chapter 50, and the SMACNA Symbols Sheet.

Candidates are responsible for bringing their own references. Approved books may be highlighted, underlined, and indexed before the examination. Permanent tabs may be used for organization. Temporary tabs such as Post-it notes are not permitted. Candidates may not write in the references before or during the examination session.

The open-book format makes reference navigation an important part of preparation. Candidates should practice identifying the subject of a question and deciding which reference is most likely to contain the answer. They should also become comfortable using indexes, chapter headings, section organization, tables, and permanent tabs.

The included highlighted and tabbed rental books are intended to support this type of preparation. Candidates should spend time learning the organization of the books during study sessions rather than waiting until exam day to become familiar with the tabs and highlighted material.

Licensing Steps

The Oklahoma Construction Industries Board regulates mechanical journeyman licensing and determines whether an applicant meets the qualifications to proceed with the Limited Residential Journeyman examination.

1. Review the Limited Residential Journeyman license scope. Confirm that this category matches the residential mechanical work you intend to perform.
2. Gain qualifying mechanical trade experience. Applicants must document experience that satisfies Oklahoma's mechanical licensing requirements.
3. Meet an accepted experience or education pathway. Oklahoma recognizes qualifying mechanical experience as well as certain approved combinations of mechanical education and work experience.
4. Complete the appropriate license application. Submit the required information and supporting documentation to the Oklahoma Construction Industries Board.
5. Receive examination authorization. The state reviews the application and determines whether the applicant is eligible to test.
6. Schedule the examination through PSI. Approved applicants proceed with examination scheduling through the testing provider.
7. Prepare using the approved references. Study the technical topics and practice efficient open-book navigation.
8. Complete the required examination. Pass the applicable Oklahoma Limited Residential Journeyman examination as part of the licensing process.

The Application Service included with this Ultimate package provides support with organizing the licensing application process. Exam preparation and Application Service work together to help candidates manage both the study and administrative portions of pursuing the Oklahoma Limited Residential Journeyman credential.

State Requirements

Applicants for an Oklahoma mechanical journeyman license must meet the qualifications established by the Oklahoma Construction Industries Board. Mechanical license applicants are required to provide proof of qualifying experience in the mechanical trade.

Applicants who are not already licensed and want mechanical experience gained in Oklahoma to count toward examination eligibility must maintain apprentice registration with the Oklahoma Construction Industries Board for the applicable Oklahoma experience.

The Limited Residential Journeyman license authorizes complete new systems in new construction for qualifying detached one- or two-family dwellings and multiple single-family dwellings, including townhouses, that are not more than three stories high and have a separate means of egress.

Within that scope, the license covers cooling systems of 5 tons or less, heating systems of 150,000 Btu/h or less, and related accessories including humidifiers, filtering systems, kitchen vent hoods, exhaust fans, and clothes dryer vent exhausts.

The license does not authorize fuel gas piping, welding, soldering, brazing, final connection of refrigerant lines, or final connection of electrical wiring permitted to be installed under Oklahoma statutes.

Candidates should also understand that a journeyman license and a mechanical contractor license are different license levels. A Limited Residential Journeyman credential establishes the applicable journeyman qualification. Candidates planning to operate as a mechanical contractor should review and satisfy the separate contractor licensing requirements that apply to their intended business activities.

Reference Books

• International Residential Code for One- and Two-Family Dwellings, 2018
  Included Book: This residential code reference is used for the Oklahoma Limited Residential Journeyman examination. Candidates should become familiar with sections addressing duct systems, vents, insulation, appliance installation, exhaust systems, access, combustion air, piping, clearances, and other residential mechanical requirements.
• Oklahoma Mechanical Industry Regulations, Oklahoma Administrative Code, Title 158, Chapter 50
  Included Book: This Oklahoma-specific reference contains regulations governing the mechanical industry, including licensing classifications, qualifications, requirements, and related state mechanical rules. It is an approved reference for the Limited Residential Journeyman examination.
• SMACNA Symbols Sheet
  Included Book: The SMACNA Symbols Sheet is used for examination questions involving mechanical and ductwork symbols. The published examination outline assigns three questions to the SMACNA Symbols category.

The included rental books are highlighted and tabbed to support faster navigation and organized preparation. Candidates should use the books repeatedly throughout their study period so the tabs, sections, and layout become familiar before the examination.

Test Information and Study Materials

Preparation for an open-book mechanical examination should include both technical review and practical book-navigation exercises. Start by dividing study sessions around the published examination topics rather than reading the references without a clear plan.

Duct systems deserve additional attention because they represent one-quarter of the 40-question examination. Candidates should practice recognizing duct-related terminology and locating the applicable residential code sections efficiently.

Vents and access requirements each account for four questions. Insulation, clothes dryer installations, appliance installation, restroom exhaust systems, piping, and SMACNA symbols each account for three questions. Range hoods, clearances, combustion air, and general installation are also included in the published examination outline.

When studying the International Residential Code, focus on understanding how the mechanical provisions are organized. Practice moving from the index to the relevant chapter and then to the specific section or table that applies to a question.

The Oklahoma Mechanical Industry Regulations should also be actively studied. Candidates should become familiar with the organization of Title 158, Chapter 50 so they can recognize when a question involves an Oklahoma-specific licensing or regulatory requirement rather than a technical residential code provision.

For the SMACNA Symbols Sheet, practice identifying the symbols and learning how the reference is organized. Familiarity can reduce the amount of time required to answer symbol-related questions during the examination.

Timed practice is another useful part of preparation. Candidates can work through sample questions using a two-and-a-half-minute average time target while practicing when to continue searching and when to move forward to another question. The objective is to develop a testing rhythm that balances accuracy with efficient use of time.

Self-study should also include regular review of highlighted sections and permanent tabs. Rather than relying on the highlighting alone, candidates should understand why a section is important and how it relates to the examination topics. Repeated navigation can help reinforce where information is located and create a more consistent study process.
