The foregoing articles constitute what I consider a comprehensive and clear description of the redesign process of a major assessment. The articles serve to illustrate the problems that will need to be addressed by large-scale assessments in the twenty-first century. Primary among them is how to organize the development of such assessments to meet…

The cornerstone of evidence-centered assessment design (ECD) is an evidentiary argument that requires that each target of measurement (e.g., learning goal) for an assessment be expressed as a "claim" to be made about an examinee that is relevant to the specific purpose and audience(s) for the assessment. The "observable evidence" required to…

Evidence-centered assessment design (ECD) explicates a transparent evidentiary argument to warrant the inferences we make from student test performance. This article describes how the vehicles for gathering student evidence--task models and test specifications--are developed. Task models, which are the basis for item development, flow directly…

An evolved form of the Edwards and Beckworth (1989) model for probability selection for Scholastic Achievement Test takers using truncated normal distributions is presented. It is shown that the arguments of Holland and Wainer are not sufficient to reject this model. (SLD)

In a coherent educational assessment system, the relation between the cut scores across the grades of a content area should reflect the goals of the educational system moderated by the state of the standards within that system. In this article, we discuss the need for consistent cut scores across the grades of a content area; we present and…

Psychometricians continue to develop and evaluate methods for linking test scores, both horizontally and vertically. This article describes a social moderation process for articulating (i.e., linking) performance standards across grade levels for an operational state assessment program. The researchers used generated data to evaluate the likely…
