In "Unique Characteristics of Diagnostic Classification Models: A Comprehensive Review of the Current State-of-the-Art," Rupp and Templin (2008) undertake the ambitious task of providing a thorough portrait of the current state of diagnostic classification models (DCM). In this commentary, the author applauds Rupp and Templin for their…

In this commentary, the author addresses what is referred to as the deterministic input, noisy "and" gate (DINA) model. The author mentions concerns with how this model has been formulated and presented. In particular, the author points out that there is a lack of recognition of the confounding of profiles that generally arises and then discusses…

Rupp and Templin (2008) do a good job at describing the ever expanding landscape of Diagnostic Classification Models (DCM). In many ways, their review article clearly points to some of the questions that need to be answered before DCMs can become part of the psychometric practitioners toolkit. Apart from the issues mentioned in this article that…

In this commentary, the authors discuss some of the issues regarding the use of diagnostic classification models that practitioners should keep in mind. In the authors experience, these issues are not as well known as they should be. The authors then provide recommendations on diagnostic scoring.

On a general level, the objective of diagnostic classifications models (DCMs) lies in a classification of individuals regarding multiple latent skills. In this article, the authors show that this objective can be achieved by multidimensional adaptive testing (MAT) as well. The authors discuss whether or not the restricted applicability of DCMs can…

A dozen different approaches that yield 13 reliability indices for criterion-referenced tests were identified and grouped into three categories: threshold loss function, squared-error loss function, and domain score estimation. Indices were evaluated within each category. (Author/RL)

Three kinds of classificatory decisions that might be made using criterion-referenced tests (CRTs) are described, and methods to appraise the validity of each are subsequently discussed. Decisions that entail predictive, descriptive, and evaluative classifications comprised the three kinds of decisions described. Predictive classifications entail…

Describes a four-tier model for designing and developing practice and assessment in computer-based training. Topics include teaching versus assessing; levels of knowledge; taxonomy levels and intended learning outcomes; and time and cost constraints that result in criterion-referenced tests being most widely used.

This paper describes the development of standardized evaluation procedures for Pasco County's inservice teacher education. Since 1983, legislation requires teacher education centers in Florida to report attainment data based on measurable objectives. Using a classification system adapted from the "Rand Change Agent Study," directors and…

Presented in the second volume on the Home-Oriented Preschool Education project are responses of a National Panel of Child Development scholars to a "prime competency list" for normal children up to 6-years-old. The competencies, drawn from a literature search, include behaviors in five categories: classification, communication,…

The need to assess students' educational needs and progress is explored, and minimum standards that local school districts must meet to be in compliance with classification and accreditation standards of the State Board of Education are specified. There are three major uses of assessment results: instructional, guidance and counseling, and…
