FIELD NOTE 01
What the Codes module is meant to measure
Use the current American Petroleum Institute outline to identify the knowledge and source-navigation work expected for API 570. Do not assume a third-party practice set reproduces the official exam.
- piping inspection practices
- corrosion rates and intervals
- repairs, alterations, and rerating
- calculations and code navigation
FIELD NOTE 02
Build a codes-first practice loop
Practice identifying the governing document, locating the relevant provision, applying it to the stated condition, and recording the result without importing an unsupported assumption.
- Classify the inspection condition
- Name the controlling reference family
- Locate the relevant provision or table
- State the decision and its limitation
FIELD NOTE 03
Keep module results diagnostic
A practice score is evidence about the questions attempted, not a prediction of an official result. Track domain, question type, lookup time, and the reason for each miss.
- Knowledge miss
- Lookup miss
- Application miss
- Pacing or transcription miss
Common questions
API 570 Codes Module, answered
How should I prepare for the API 570 Codes module?
Use the current official outline, build a reference index, complete original application questions, and review misses by domain and cause.
Does a HoldPoint Codes result equal an official result?
No. HoldPoint practice is independent preparation evidence; the credentialing body controls the official examination and result.

Exam policies, fees, references, and eligibility can change. HoldPoint is independent and uses American Petroleum Institute as the authority for current program facts.
