Study structure
Trade-specific study outlines and self-assessment are implemented in our development framework.
In development

We’re building a dedicated Heavy Duty Equipment Technician app using the same study framework as our Steamfitter/Pipefitter app.
This app is not available to buy or download yet.

Occupational standards for Heavy Duty Equipment Technician

Some current exams still use a National Occupational Analysis (NOA). A newer RSOS does not automatically replace the standard used for current exams.
