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 work with NFT or deep water culture systems: mixing A/B stock tanks, calibrating EC and pH probes, adjusting LED photoperiod and spectra, seeding and transplant cycles.
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 crop varieties grown, target EC and pH ranges by growth stage, and yield per square metre achieved across repeated harvest cycles.
02
Evaluation factor
Safety discipline
30% weight
Probe food safety and chemical handling: GAP or GlobalG.A.P. audits, sanitation of grow trays between cycles, pesticide or biocontrol records, working at height on rack lifts, lockout for pumps.
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
Treats sanitation logs and biosecurity gowning as routine, cites specific audit findings closed and refuses shortcuts on chemical dilution.
03
Evaluation factor
Fault finding
20% weight
Test diagnosis of crop and system problems: tipburn versus calcium lockout, root rot from warm reservoirs, clogged drippers, failed dosing pump, HVAC dehumidification struggling at high VPD.
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 through a real crop failure, the sensor data and leaf symptoms compared, and the corrective change that restored consistent quality.
04
Evaluation factor
Reliability and conduct
15% weight
Assess shift reliability in a living system: weekend and holiday cover, handover notes in the environmental control software, scouting sheets for thrips or powdery mildew, harvest deadlines.
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
Describes owning daily walkthroughs without prompting, logging deviations promptly, and covering unplanned shifts when a reservoir or chiller alarm hits.
