INTEGRATED PSYCHOMETRIC ASSESSMENT FRAMEWORK
EXECUTIVE OVERVIEW
Purpose of This Presentation
- Explain the integrated assessment methodology used for equipment operator candidate evaluation
- Clarify classification criteria and decision-making frameworks
- Outline organizational implications for implementation and resource allocation
- Provide actionable insights for strategic workforce planning
Key Takeaway
The integrated assessment approach combines psychomotor capability testing with cognitive learning potential evaluation to provide comprehensive, evidence-based hiring recommendations that balance immediate operational needs with long-term strategic value.
PART 1: ASSESSMENT METHODOLOGY
The Two-Pillar Assessment Framework
Our integrated approach evaluates candidates across two critical dimensions:
PILLAR 1: Dover Psychomotor Test
What It Measures: Physical and motor skills essential for equipment operation
- Reaction time and speed (normal, stress, recovery conditions)
- Visual processing and pattern recognition
- Hand-eye coordination and precision
- Movement control and spatial estimation
- Crisis management under pressure
Why It Matters: Operators require rapid responses, precise motor control, and consistency under pressure; poor psychomotor performance correlates with safety incidents and inefficiency.
PILLAR 2: LPCAT Cognitive Assessment
What It Measures: Learning potential and reasoning capacity
- Non-verbal figural reasoning ability
- Pattern recognition and abstract thinking
- Learning capacity (pre/post improvement)
- Cognitive ceiling and developmental potential
- Training readiness and complexity tolerance
Why It Matters: Cognitive capacity predicts training success, problem-solving, compliance, and advancement potential.
PART 2: CLASSIFICATION CRITERIA
Dover Test Classification System
Grading Framework
| Grade | Symbol | Performance | Score Range | Operational Meaning |
|---|---|---|---|---|
| A | 🟢 | Good/Excellent | Top 25% | Exceeds operational requirements |
| B | 🟡 | Average/Acceptable | Middle 50% | Meets operational requirements |
| C | 🔴 | Poor/Below Standard | Bottom 25% | Below operational requirements |
Component Assessments
- Lights & Sound (Reaction) — Normal, Stress/Crisis, Recovery
- Squares (Visual Processing) — Perception & recognition speed
- Coordination — Mean duration (speed) & error % (precision)
- Movement Control — Deviation time & direction deviation
- Shapes — Pattern recognition speed & accuracy
Overall Dover Score Interpretation
| Score Range | Grade | Classification | Hiring Implication |
|---|---|---|---|
| 70–100% | A/B+ | Above Avg – Excellent | Strong candidate — standard hiring |
| 60–69% | B/C+ | Average – Below Avg | Conditional — enhanced training |
| 50–59% | C | Below Average | High risk — intensive intervention |
| < 50% | C- | Poor | Not recommended |
Industry Standard: Most mining operations require minimum 70% Dover score for operator roles without conditions.
LPCAT Classification System
T-Score Framework
Mean 50, SD 10, typical range 20–80.
Stanine Framework
| Stanine | T-Score | Percentile | Classification | Population % |
|---|---|---|---|---|
| 9 | 65+ | 96–99 | Very Superior | 4% |
| 8 | 60–64 | 89–95 | Superior | 7% |
| 7 | 55–59 | 77–88 | Above Average | 12% |
| 6 | 50–54 | 60–76 | High Average | 17% |
| 5 | 46–49 | 40–59 | Average | 20% |
| 4 | 41–45 | 23–39 | Low Average | 17% |
| 3 | 36–40 | 11–22 | Below Average | 12% |
| 2 | 31–35 | 4–10 | Poor | 7% |
| 1 | < 31 | 1–3 | Very Poor | 4% |
Educational Level Equivalents & Learning Gain
| T-Score | Stanine | Educational Level | NQF Equivalent | Operator Relevance |
|---|---|---|---|---|
| 55–65+ | 7–9 | Tertiary (Diploma–Degree) | NQF 5–7 | Exceeds requirements |
| 50–54 | 5–6 | Middle–Senior Secondary | NQF 3–4 | Meets requirements |
| 45–49 | 3–4 | Junior Secondary | NQF 2–3 | Below requirements |
| 40–44 | 1–2 | Senior Primary | NQF 1–2 | Well below |
| < 40 | 1–2 | Primary | Below NQF 1 | Disqualifying |
Learning Gain Interpretation
- +5 or more — Strong capacity; high training ROI
- +2 to +4 — Moderate capacity; standard effectiveness
- -1 to +1 — Minimal learning/high baseline
- -2 to -5 — Negative pattern; concerns
Critical Threshold for Operators: Minimum Stanine 4–5 (T 41–50).
PART 3: INTEGRATION METHODOLOGY
How We Combine Dover + LPCAT Results
- Individual Assessment Evaluation — Analyze Dover components, evaluate LPCAT level & learning potential, map against role requirements.
- Cross-Domain Analysis — Four profiles:
Profile Type Dover LPCAT Risk Recommendation Ideal Candidate High (70%+) High (Stanine 5+) Low Standard hiring Cognitive Compensator 55–69% Stanine 6+ Moderate Conditional; training can compensate Capable Executor 70%+ Stanine 4–5 Low–Moderate Approve; limited advancement High Risk < 60% Stanine ≤3 High Do not recommend - Integrated Risk Assessment — Safety, Equipment Handling, Training Complexity, Performance Consistency, Operational Capability.
- Business Context Integration — Age/runway, training capacity, safety tolerance, alternative roles, strategic needs.
PART 4: RECOMMENDATION FRAMEWORK

- Dover ≥70% (or 65–69% with no C in critical areas)
- LPCAT Stanine ≥5
- No significant safety risks; consistent profile
Actions: Standard onboarding, regular training, normal supervision, 3‑month probation.
🟡 CONDITIONAL — Enhanced Support
- Dover 55–69% with LPCAT ≥6, or Dover ≥70% with LPCAT 4
