Getting the First and Second Decimals Right: Psychometrics of Stealth Assessment


Stealth assessment, like all assessments, must have three essential psychometric properties: validity, reliability, and fairness. Evidence-centered assessment design (ECD) provides a psychometrically sound framework for designing assessments based on a validity argument. This chapter describes how using ECD in the design of a stealth assessment helps designers meet the psychometric goals. It also discusses how to evaluate a stealth assessment’s validity, reliability, and fairness after it is designed and implemented.
