Assessment Expert Witnesses
Assessments drive high-stakes decisions about credentials, admissions, institutional standing, and risk, so disputes over how they were designed, administered, and interpreted can carry substantial consequences. Testing companies and professional licensing bodies face challenges to exam scoring, scaling, and equating, while educational institutions contest accreditation decisions and the evidence used to evaluate their programs. State agencies and school districts litigate with assessment vendors over contract performance and test validity, and organizations dispute the methodology behind risk assessments used to support regulatory, insurance, or business decisions. In each setting, the core question is whether an assessment was valid, reliable, and applied in a manner consistent with accepted professional standards.
An assessment expert addresses that question through the established principles of measurement and evaluation. The expert can examine test specifications, item analyses, scoring and equating procedures, and validation studies to determine whether an instrument measured what it claimed to measure and produced consistent results across forms and populations. In accreditation and program evaluation disputes, the analysis evaluates whether evidence was gathered and interpreted according to recognized standards, while risk assessment matters call for scrutiny of data quality, statistical methods, and underlying assumptions. These findings help counsel challenge or defend adverse decisions, establish whether a vendor or institution met its obligations, and expose methodological flaws in an opposing analysis.
Assessment expertise is highly specialized, and an expert in psychometrics brings a very different perspective than one in accreditation, program evaluation, or quantitative risk analysis. Round Table Group's network includes psychometricians who have published on item response theory, scaling, linking, and equating and testified on exam scoring, along with specialists in computerized adaptive testing, educational measurement, academic accreditation, and medical education curriculum and assessment. Others bring expertise in statistical risk analysis, epidemiology, human factors, and food toxicology, including a researcher whose work for the U.S. Department of Transportation led to the center high-mounted brake light requirement for automobiles.
