Leading universities
Academic research spanning motivation, engagement, psychometrics, and organizational behavior.
Psychometrics & Methods
Evidence-grade measurement science for decisions you can defend—from research labs to real operations.
Explore the ToolkitNational research institutions
High-stakes assessment and workforce measurement in credentialing and public-interest contexts.
Big tech & consulting
People analytics, selection science, and product-adjacent analytics with a bias for operational use.
Core capabilities
Scale design & validation
Construct mapping, item writing, content validity, pilot testing, power planning, and revision protocols.
Factor models (EFA/CFA)
Dimensionality, cross-loadings, fit diagnostics, bifactor/higher-order models, and residual checks.
Reliability & generalizability
α/ω coefficients, hierarchical ω, test–retest, inter-rater models, and G-theory for facet variance.
IRT & score engineering
1–3PL/GRM/GPCM, item banks, CAT readiness, information functions, scale linking, and score banding.
Validity evidence
Convergent/discriminant patterns, criterion/predictive evidence, known-groups, sensitivity to change.
Measurement invariance
Configural/metric/scalar/strict checks, partial invariance protocols, subgroup stability reporting.
Fairness, risk & governance
DIF & subgroup audits
Uniform/non-uniform DIF, item-level flags, impact analyses, and mitigation plans with transparent trade-offs.
Bias-aware modeling
Parsimony + interpretability, protected-attribute handling, stability checks, and decision logs.
Model cards for measures
Scope, assumptions, intended use, limitations, and monitoring cadence—measurement as a governed asset.
Methods in practice
Selection & leadership
Structured interviewing, multiple-hurdle designs, adverse-impact review, and score cutoffs tied to utility.
Engagement & culture
Driver analysis with validated scales, team-level norms, and action heuristics with practical effect sizes.
Learning & performance
Competency models, mastery thresholds, assessment-for-learning loops, and longitudinal sensitivity.
Health & safety
Brief, validated instruments for fatigue, cognitive load, and risk awareness that survive operational constraints.
Artifacts & deliverables
Scoring & interpretation
Score keys, norms, banding, and interpretation tables with uncertainty guidance.
Technical appendix
Model specs, fit indices, item parameters, reliability & invariance evidence, and data-quality checks.
Operator brief
Plain-language “how to use” for leaders and practitioners; guardrails and change thresholds.
Case snapshots
Selection utility realized
Score-based thresholds raised quality-of-hire indices at steady pass rates; zero flagged DIF after revisions.
Engagement measure tuning
Re-factoring improved reliability (ω↑) and clarified team-level variance components for action planning.
Learning outcomes sensitivity
IRT-based forms detected meaningful change with fewer items, reducing burden and boosting completion.
Methods library
Deeper write-ups and templates for factor analysis, reliability families, IRT models, DIF, invariance, and score engineering.
