On the science of the assessment itself: Validated assessments combine self-report items with rubric-scored responses, producing a percentile profile against a normed reference sample. The strongest instruments report internal consistency above . and test-retest reliability above . over multi-week intervals, with construct validity established against external behavioural and outcome measures rather than self-judgment alone. Construct definition: Postal Service Mail Carriers, treated psychometrically, denotes a latent disposition inferred from converging behavioural indicators rather than a single observable. The instruments cited downstream measure the construct through rubric-scored item responses, with criterion validity established against external outcomes — supervisor ratings, longitudinal panel data, or audit-study callbacks — rather than self-perception alone. A note on uncertainty: every effect size on this page sits inside a confidence interval, and most intervals are wider than the published headline implies. Treat percentage shifts as directional rather than precise. Where a finding originates in a single underpowered study, we annotate that explicitly; where it has been replicated, the annotation flags the replication count. Nothing on this page should be read as a forecast — historical effect sizes establish a prior, not a prediction, for Postal Service Mail Carriers/OPA Policy Engine.
