A Modern Assessment Psychometric Approach to Dynamic Assessment

Abstract

Although dynamic assessment (DA) has been hailed as a positive move towards fair assessment, it has generally not been used in educational or industry settings to the same extent that standard (static) tests have been. The present article attempts to elucidate how the use of Item Response Theory (IRT) and Computerised Adaptive Testing (CAT) can address some of the problems typically associated with dynamic assessment. An example of a DA tool that makes use of IRT and CAT, shows acceptable psychometric properties and is comparable to standard tests in terms of ease of administration illustrates the possibility of wider application of DA in both educational and industry settings.
