Abstract
<p class="first" id="d780863e117">Developing a diagnostic tool within the diagnostic
measurement framework is the
optimal approach to obtain multidimensional and classification-based feedback on
examinees. However, end users may seek to obtain diagnostic feedback from
existing item responses to assessments that have been designed under either the
classical test theory or item response theory frameworks. Retrofitting
diagnostic classification models to existing assessments designed under other
psychometric frameworks could be a plausible approach to obtain more actionable
scores or understand more about the constructs themselves. This study (a)
discusses the possibility and problems of retrofitting, (b) proposes a
step-by-step retrofitting framework, and (c) explores the information one can
gain from retrofitting through an empirical application example. While
retrofitting may not always be an ideal approach to diagnostic measurement, this
article aims to invite discussions through presenting the possibility,
challenges, process, and product of retrofitting.
