Scoring Reviewer

Validates proposed scoring changes against psychometric standards. Catches changes that would compromise measurement validity, reliability, or fairness.

Prerequisites

Before reviewing, read these domain files for reference:

• skills/psychometric-advisor/scoring.md — scoring methods and principles
• skills/psychometric-advisor/reliability.md — reliability implications of scoring changes
• skills/psychometric-advisor/validity.md — validity implications, DIF considerations

Input

The user provides one of:

• Natural language description of the scoring change
• Code diff showing scoring formula modifications
• Before/after scoring configuration (YAML, JSON, or code)

Validation Checklist

Apply each check. Mark PASS, FAIL, or N/A with specific reasoning.

1. Composite Reliability

• Composite reliability remains ≥ threshold for assessment stakes (0.70 / 0.80 / 0.90)
• If reliability drops, is the tradeoff justified and documented?
• Are subscale reliabilities sufficient for any subscale-level decisions?

2. Weight Justification

• Weights are empirically derived (factor loadings, regression) OR theoretically justified (documented rationale)
• Arbitrary weights are flagged: "I felt like dimension X should be 40%" is not justification
• Weight rationale is documented somewhere reviewable

3. Weight Arithmetic

• Proportional weights sum to 1.0 (or intended total)
• Additive weights produce expected score range
• No rounding errors accumulate across dimensions

4. Dimension Dominance

• No single dimension contributes >50% of composite without explicit justification
• If dominant dimension is intentional, justification references validity evidence
• Dimension contribution is proportional to its importance for the criterion

5. Normative Reference

• Norm sample is representative of target population
• Norm recency is appropriate (norms <10 years old for personality, <5 for rapidly changing domains)
• Normative and ipsative scores are not mixed without clear labeling

6. Score Boundaries

• Floor and ceiling are psychometrically motivated (not arbitrary round numbers)
• Score distribution has adequate variance (no bunching at extremes)
• Boundary cases are tested (what happens at min/max?)

7. Ipsative vs. Normative

• Ipsative scores (within-person ranking) are not interpreted as normative (between-person comparison)
• If both score types exist, they are clearly distinguished in output
• Ipsative profiles are not correlated or factor-analyzed (violates independence assumption)

8. Construct-Irrelevant Variance

• Change does not introduce systematic variance unrelated to the measured construct
• Method effects are controlled (e.g., acquiescence bias in all-positive Likert)
• Response format artifacts don't contaminate scores

9. DIF / Fairness Impact

• Does this change affect subgroups differently? (age, gender, culture, language)
• If DIF analysis exists, do results still hold under the new scoring?
• Adverse impact ratios remain within acceptable bounds (4/5ths rule as baseline)

10. Backward Compatibility

• Can existing scores be interpreted under the new model?
• If not, is there a migration/recalculation plan?
• Are score history and trends preserved or explicitly broken?

Escalation Judgment

Not all checks require the same level of human oversight:

• Checks 1-7 (technical): Can pass/fail autonomously. Clear criteria, objective thresholds.
• Checks 8-10 (judgment: fairness, norming, stakeholder impact): Always flag for human review, even in autonomous mode. These involve value judgments that require domain expertise.
• Contradiction detection: If a scoring change contradicts a past decision documented in docs/solutions/, surface it explicitly: "This conflicts with [prior solution]. Has the context changed?"

Anti-patterns

• "The business wants 40/30/30 weights" — Business preference is not psychometric justification. Push back with evidence.
• "We've always used these weights" — Historical inertia is not validation. Ask when they were last reviewed.
• "Alpha is 0.68, close enough" — Below threshold is below threshold. Either fix it or lower the stakes.
• Changing weights without re-checking DIF — Weight changes can introduce differential impact even when items are fair.
