Weighted scoring multiplies each item's result by its importance before summing—how to set weights defensibly and keep them explainable.
A weighted score gives each item a share of the final number proportional to what it matters, not just how many points it happens to carry: Σ(wᵢ × sᵢ)/Σwᵢ. It's the difference between a quiz and an assessment.
Total = Σ(weight × item score) / Σ(weights), weights typically 1-5 or percentage shares.
In a manager exam, safety items carry weight 5 and logistics weight 1—failing safety can no longer be laundered by acing the easy stuff.
Whenever stakes differ across dimensions—certifications, readiness gates, vendor scoring. Equal weights are a decision too, just an implicit one.
Weights must survive the "explain it to the failed candidate" test. If you can't defend a 3 vs a 5, use equal weights and say so.
Both, usually: weights shape the score, thresholds (must-pass items) guard it. A weighted average alone can still hide fatal gaps.
Stakes-based expert panels or regression against a criterion. Document the rationale—weights without a story are decoration.
