Complete evaluation framework
What to assess and how to score it
Review the evidence signals before interviewing. Then use the anchored descriptions—not instinct alone—to choose the score that best matches each answer.
01
Evaluation factor
Hands-on competence
35% weight
Check hands-on calibration of safety-related loops: pressure transmitters, RTDs, thermocouples, bistables, using Fluke 754 or similar, plus as-found/as-left data and setpoint drift trending.
Evidence to listen for
Names the equipment, materials, and tolerances they work to
Can describe a job start to finish without hand-waving the hard parts
Holds the tickets, licences, or certifications the work requires, and they are current
Knows what they are not qualified to touch
Five-point scoring guide
1
Poor
Cannot describe the work concretely; lacks required tickets or licences.
2
Needs Improvement
Basic familiarity; needs supervision on routine tasks.
3
Satisfactory
Competent on standard work; slower or unsure on unfamiliar jobs.
4
Very Good
Skilled and independent across the normal range of the role.
5
Excellent
Names specific loops and instruments calibrated, quotes tolerance bands, and explains how as-found data fed drift and surveillance records.
02
Evaluation factor
Safety discipline
30% weight
Probe radiological and electrical safety habits: RadWorker II training, ALARA planning, dose tracking, clearance and lock-out tag-out on protection channels, and jumper and lifted-lead control.
Evidence to listen for
Treats procedure as protection rather than paperwork
Can describe a time they stopped work and why
Knows the specific hazards of this trade and the controls for each
Reports near misses instead of hiding them
Five-point scoring guide
1
Poor
Casual about safety; describes shortcuts with pride.
2
Needs Improvement
Follows procedure when watched; cannot name the hazards that matter.
3
Satisfactory
Sound safety habits; less certain on unfamiliar hazards.
4
Very Good
Safety is instinctive; can describe stopping work over a real concern.
5
Excellent
Describes stopping work over an incorrect clearance boundary and treats independent verification and dose minimisation as routine, not optional.
03
Evaluation factor
Fault finding
20% weight
Test troubleshooting of spurious trips and channel failures: neutron flux instrumentation, isolation amplifiers, noisy signals, grounding faults, using prints, loop diagrams and signal tracing.
Evidence to listen for
Has a method for narrowing a fault rather than swapping parts
Reads schematics, manuals, or error codes and acts on them
Knows when to escalate rather than guess
Can describe a fault that took real work to find
Five-point scoring guide
1
Poor
Parts-swapper; no diagnostic method.
2
Needs Improvement
Fixes symptoms; cannot explain how they found the cause.
3
Satisfactory
Solid on familiar faults; less structured on new ones.
4
Very Good
Clear systematic method with a real hard-fault story.
5
Excellent
Walks a spurious bistable actuation from symptom to root cause, distinguishing sensor, cabling, and card failures with evidence at each step.
04
Evaluation factor
Reliability and conduct
15% weight
Assess work practice discipline: technical specification surveillance deadlines, work order documentation in Passport or Maximo, condition reports written, and shift or outage callout availability.
Evidence to listen for
Turns up, on time, prepared
Handles shift work, callouts, or travel as the role requires
Documents work so the next person can pick it up
Deals with customers or site staff professionally
Five-point scoring guide
1
Poor
Unreliable attendance; unprofessional on site.
2
Needs Improvement
Inconsistent; documentation is an afterthought.
3
Satisfactory
Dependable; paperwork is adequate.
4
Very Good
Consistently reliable, documents well, professional with customers.
5
Excellent
Shows clean surveillance completion history, self-reported own errors through condition reports, and worked full refuelling outages without schedule slippage.
