Whether you are advancing from Journeyman Plumber status or preparing for the professional responsibilities of a Master Plumber Class I, this course provides a structured approach to examination preparation and technical knowledge development.

Exam Details

The Georgia Master Plumber Class I examination evaluates advanced plumbing knowledge and the ability to apply technical concepts, installation requirements, code provisions, and professional responsibilities to practical situations.

Georgia plumbing licensing is administered by the State Construction Industry Licensing Board, Division of Master and Journeyman Plumbers. Approved licensing examinations are delivered through PSI.

Georgia Master Plumber Class I Examination Overview:

  • License Classification: Statewide Master Plumber Class I (Restricted)
  • Licensing State: Georgia
  • Licensing Authority: Georgia State Construction Industry Licensing Board, Division of Master and Journeyman Plumbers
  • Examination Provider: PSI
  • Examination Format: Computer-based, multiple-choice examination
  • Testing Method: Closed book
  • Scored Questions: 120
  • Additional Unscored Questions: 24
  • Total Questions: 144
  • Examination Time: Seven hours, divided into two parts
  • Passing Standard: Minimum final scaled score of 70

The examination includes technical plumbing subjects together with administrative, business, and design-related knowledge. Candidates should prepare for questions involving plumbing codes, system installation, maintenance, planning, material selection, calculations, and professional responsibilities.

Plumbing examination preparation also involves understanding how regulations apply in Georgia. The 2024 Georgia Plumbing Code and 2024 Georgia Fuel Gas Code incorporate the corresponding International Codes and Georgia-specific amendments.

The online course supports preparation by encouraging students to review these subjects systematically, strengthen technical understanding, and practice applying plumbing principles independently.

Closed Book Test

The Georgia Master Plumber Class I (Restricted) examination is a closed-book test. Candidates cannot consult plumbing codes, technical manuals, reference books, or personal study notes during the examination.

This examination format places particular importance on understanding and remembering plumbing principles. Candidates must recognize technical problems, interpret practical scenarios, and apply code-related knowledge without searching for answers in a reference book.

For example, a drainage question may involve applying pipe sizing principles or understanding proper venting arrangements. A fuel gas question may involve identifying safe installation practices, appliance connections, or combustion air requirements.

Questions involving plumbing mathematics may require measurements, conversions, slope calculations, or other technical operations. Professional responsibility questions may address contractor management, workplace safety, and applicable regulations.

Effective closed-book examination preparation strategies include:

  • Studying major plumbing code requirements and their practical applications.
  • Reviewing water supply, drainage, venting, and fuel gas concepts.
  • Practicing plumbing calculations without relying on worked examples.
  • Learning common installation terminology and material requirements.
  • Reviewing Georgia-specific plumbing and fuel gas provisions.
  • Strengthening understanding of safety and business responsibilities.
  • Using practice-oriented review to identify subjects needing additional attention.

Students can begin preparation by studying the appropriate technical references, then reviewing important concepts from memory. This approach supports the development of practical knowledge rather than relying entirely on memorized code section numbers.

Understanding why a plumbing requirement exists can also make technical information easier to remember. Connecting written standards to actual installations, system performance, and safety considerations strengthens examination preparation.
