Cognitive Diagnostic Modeling

  • Cognitive Diagnostic Models
    The purpose of this document is to provide theoretical background on cognitive diagnostic models by first explaining some technical terminology and then providing an overview of the models that could be used in practice. The purpose of this is to prime the way for more analyses regarding these types of diagnostic assessments, in an overall effort to provide background information about commonly studied diagnostic models that could be useful for the stakeholders of such tests, particularly in the state of Maryland. Ultimately, we hope that this review will shed light on the models that will be most useful for giving students and teachers accurate and useful information for the use of formative assessments as proposed by the CCSSO, PARCC, and Maryland public schools.
