Job-readiness and assessment field guide
CCST practical 028 assessment: readiness checklist
Direct answer
The candidate can identify document assumptions, predict key states, compare measurements and defend a repair with repeatable functional evidence.
Written for controls candidates translating a diagram and functional description into a safe, testable diagnostic plan.
Role scope
Document revision, equipment state, energy boundary, symbols, terminal identity, expected values, operating mode, symptom and acceptance criteria.
Skills map
Functional requirement through drawing, field devices, conductors, controller I/O, logic, outputs, equipment response and retained test record.
Core exercise
The candidate predicts and observes a complete normal path before isolating the declared abnormal state.
Stretch case
Outdated drawing, ambiguous terminal, wrong mode, backfeed, intermittent connection, retained command, power return and undocumented modification.
Troubleshooting
A requirement, document, field, wiring, I/O, program, output, equipment or feedback mismatch.
Portfolio evidence
The record reviewed against current controlled documents, procedures and certification-body objectives.
How should a candidate use a control drawing during diagnosis?
Confirm revision and operating state, mark the expected signal path, predict values at safe test points and compare evidence from source toward the first disagreement.
What proves a repair is complete?
Remove temporary changes, restore configuration, repeat normal and relevant fault cases, verify stop and restart behavior and retain an explainable record.
