Open Book Test

The Oklahoma Plumbing Contractor and Natural Gas examination is an open-book test. Candidates may consult approved examination references under PSI testing requirements.

Open-book examinations require familiarity with technical materials and the ability to locate code provisions efficiently. Candidates must identify the subject being tested, select the appropriate reference, and interpret requirements within the examination time limit.

Oklahoma adopted the 2024 International Plumbing Code and 2024 International Fuel Gas Code with state amendments effective September 14, 2026.

The updated examination transition period for the Oklahoma Plumbing Contractor and Natural Gas examination runs from October 8, 2026, through January 8, 2027. During this period, affected candidates may test using either the previously adopted or newly adopted code.

Beginning January 9, 2027, the affected examination will use the newly adopted codes exclusively.

PSI allows approved examination references to be highlighted, underlined, and indexed. Permanent tabs are permitted, while temporary removable tabs are not allowed.

The highlighted and tabbed rental books support repeated reference navigation practice. Candidates can become familiar with plumbing code tables, fuel gas requirements, technical calculations, and related examination subjects before testing.

With 180 minutes available for 85 scored questions, effective time management and technical reference familiarity are valuable preparation skills.

State Requirements

Plumbing and natural gas contracting in Oklahoma operates within the state's regulated plumbing industry. The Oklahoma Construction Industries Board administers the applicable plumbing licensing laws and administrative regulations.

Plumbing contracting involves work associated with water supply, drainage, venting, fixtures, piping systems, and related installations. Natural gas work adds technical responsibilities involving fuel gas piping, regulators, system connections, testing, and safety.

Oklahoma's adopted plumbing and fuel gas codes establish installation requirements, subject to applicable state amendments.

Contractor licensing differs from journeyman licensing. Operating an independent plumbing contracting business requires the appropriate contractor authorization and compliance with applicable professional requirements.

Contractors also need familiarity with construction business management, legal payment rights, administrative regulations, and professional obligations.

The additional Oklahoma legal and business references included in this Ultimate Package provide resources for studying these responsibilities.
