McGrath presents a prototyping proposal to better classify character education programs. He proposes 7 key elements that can facilitate identifying more and less typical programs. This proposal appears to be a very good start for improving the organization of the character education field and facilitating research. This commentary highlights 4…

The six primary papers in this issue of "Assessment in Education" emphasise a single primary point: the concept of validity is a complex one. Essentially, validity is a collective noun. That is, just as a group of players may be called a team and a group of geese a flock, so too does validity represent a variety of processes and…

This special issue of "Assessment in Education" contains the type of debate needed about what Cizek (2015) calls a "… lingering flaw in the concept of validity…." Some practitioners might not agree that the current theory of validation is flawed. Specifically, the debate Jon Twing is referencing concerns the role of the…

Daniel Koretz is the Henry Lee Shattuck Professor of Education at the Harvard Graduate School of Education. His research focuses on educational assessment and policy, particularly the effects of high-stakes testing on educational practice and the validity of score gains. He is the author of "Measuring Up: What Educational Testing Really Tells…

There is something about the topic of validity that seems to provoke dissatisfaction in many of those who encounter it--a sense that something is not right, and that something needs to be done to sort it out. Paul E. Newton in his target essay does not attempt a radical reconstruction of the validity edifice. His position is that the "consensus…

This paper presents the authors' critique on "Clarifying the Consensus Definition of Validity" by Paul E. Newton (this issue). There are serious differences of opinion regarding the topic of validity. Newton is aware of these differences, as made clear by his choice of references and particularly his effort to respond to the various Borsboom…

The distinction between facts and moral values is highly desirable: science and politics should keep to their own territories. Traditionally speaking, science can be seen as an ivory tower, which attempts to do its job in isolation of external influences. Politics does not mandate methods of scientific research or standards of justification;…

This focus article provided the author with an opportunity to unpack the consensus definition of validity and to explore its implications in the light of recent debates. He proposed an elaboration of the consensus definition, which was intended to express the spirit of the "Standards for Educational and Psychological Testing" with increased…

I congratulate Paul E. Newton on a thoughtful and evenhanded contribution to test validity theory. I especially appreciate the evident care that went into interpreting the various authors whose work Newton discusses. I found many useful insights along with the few minor points with which I might quibble. I comment on three aspects of Newton's…

This paper presents the author's critique to Paul E. Newton's article titled "Clarifying the consensus definition of validity." In his article, Newton not only clarifies but also redefines the consensus definition of validity. In this redefinition he omits the term "construct" and introduces the term "measurement." Both omission and introduction…

Paul E. Newton's article is valuable in many ways, especially for clarifying confusions and inconsistencies in the assessment business. Most importantly, he points out confusions that persist and where open discussion will help us understand what we say and what we mean to say. But I will focus here on the only faults I find in the article: three…

Paul E. Newton provides an insightful and scholarly overview of central issues in validity theory. As he notes, many of the conceptual problems in validity theory derive from the fact that the word "validity" has two meanings. First, it indicates "whether a test measures what it purports to measure." This is a factual claim about the psychometric…

In his article, Paul E. Newton has conducted a review of selected perspectives on validity theory with the goal of disambiguating the definition of validity and describing a consensus definition of validity. Newton provides a nuanced discussion of the evolution of the concept of validity over the years. His Focus article has two major goals: (1)…

"Better Evidence, Better Choices, Better Schools," a recent report from the Center for American Progress and the Knowledge Alliance, focuses on the evidence-based research provisions in the Every Student Succeeds Act (ESSA). ESSA provisions ask districts and schools to consider various sources of evidence, make judgments about the…

Paul E. Newton argues in favor of a conception of validity, viz, "the consensus definition of validity," according to which the extension of the predicate "is valid" is a subset of "assessment-based decision-making procedure[s], which [are] underwritten by an argument that the assessment procedure can be used to measure the attribute entailed by…
