Open Book Test

The Missouri Springfield ICC Journeyman Gas Fitter 678-MO-S examination is an open book test. The examination permits the 2018 International Fuel Gas Code as its designated reference.

Open-book testing requires more than bringing a code book to the examination. Candidates must understand how the IFGC is organized and how to identify the provisions relevant to specific gas fitting situations.

Gas fitting questions may describe piping arrangements, equipment installation conditions, appliance requirements, or venting situations. Recognizing the subject of a question helps you locate the appropriate chapter, section, or table.

Effective open-book preparation includes:

  • Learning the structure of the 2018 International Fuel Gas Code.
  • Becoming familiar with important code definitions.
  • Practicing navigation through gas piping requirements.
  • Reviewing fuel gas sizing tables and their applications.
  • Studying appliance installation provisions.
  • Understanding combustion air and venting concepts.
  • Reviewing the organization of technical tables and exceptions.
  • Practicing gas fitting questions within realistic time limits.

When using the code, pay attention to the installation conditions described in each question. Equipment type, piping material, gas demand, venting arrangement, and location can influence the applicable requirement.

Developing a consistent method for identifying these details can improve both code interpretation and examination efficiency.

Licensing Steps

Passing an ICC examination and receiving local trade certification are separate steps. The city evaluates the application and supporting qualifications before issuing the applicable credential.

State Requirements

Missouri does not use a single mandatory statewide Journeyman Gas Fitter examination for every municipality. Local jurisdictions establish the requirements for gas fitting trade certification.

For this examination, the relevant jurisdiction is Springfield, Missouri.

Springfield's journeyman trade certification process recognizes qualifying experience through two principal pathways:

  • Supervised Trade Experience: Four years of experience under the supervision of a master in the applicable trade.
  • Alternative Experience Pathway: Six years of experience in the applicable trade.
  • Examination: A qualifying examination score of at least 75% under Springfield's certification requirements.
  • Application Approval: Review and approval through the city's applicable building trade certification process.

The Springfield Journeyman Gas Fitter examination focuses on the technical principles governing fuel gas installations. Candidates should understand both those principles and the local responsibilities associated with their certification.

Trade certification does not automatically authorize an individual to assume responsibilities reserved for a master-level professional or registered contractor.

Working within the authorized scope of certification and following local permitting and inspection requirements are essential parts of professional gas fitting practice.
