Combining methods from earlier content validity and more contemporary content alignment studies may allow a more complete evaluation of the meaning of test scores than if either set of methods is used on its own. This article distinguishes item relevance indices in the content validity literature from test representativeness indices in the…

In achievement testing there is typically a practical requirement that the set of items administered should be representative of some target content domain. This is accomplished by establishing test blueprints specifying the content constraints to be followed when selecting the items for a test. Sometimes, however, students give disengaged…

Evidence of comparability is generally needed whenever there are variations in the conditions of an assessment administration, including variations introduced by the administration of an assessment on multiple digital devices (e.g., tablet, laptop, desktop). This article is meant to provide a comprehensive examination of issues relevant to the…

Equating test forms is an essential activity in standardized testing, with increased importance with the accountability systems in existence through the mandate of Adequate Yearly Progress. It is through equating that scores from different test forms become comparable, which allows for the tracking of changes in the performance of students from…

In the last few years, the Advanced Placement (AP) Program[R] has used evidence-centered assessment design (ECD) to articulate the knowledge, skills, and abilities to be taught in the course and measured on the summative exam for four science courses, three history courses, and six world language courses; its application to calculus and English…

In operational testing programs using item response theory (IRT), item parameter invariance is threatened when an item appears in a different location on the live test than it did when it was field tested. This study utilizes data from a large state's assessments to model change in Rasch item difficulty (RID) as a function of item position change,…

Describes the Texas test development process in detail, showing how each test development step is linked to the "Standards for Educational and Psychological Testing." The routine use of this process provides evidence of the content and curricular validity of the Texas Assessment of Academic Skills. (SLD)

Causes of local item dependence in a large-scale performance assessment were studied using data from the Maryland School Performance Assessment Program. Contextual characteristics (content and response requirements) were identified to differentiate locally independent and dependent item clusters. Hypothesized explanations are offered for high…

Considers the situation in which content or administrative considerations limit the way in which a test can be partitioned to estimate the internal consistency reliability of the total test score. Demonstrates that a single-valued estimate of the total score reliability is possible only if an assumption is made about the comparative size of the…

Reviews general approaches to job analysis and considers methodological issues related to sampling and the development of rating scales used to measure and describe a profession or occupation. Evaluates the usefulness of different types of test plans and describes judgmental and empirical methods for using practice analysis data to help develop…

This simulation investigated two procedures that reduce differences between paper-and-pencil testing and computerized adaptive testing (CAT) by making CAT content sensitive. Results indicate that the price in terms of additional test items of using constrained CAT for content balancing is much smaller than that of using testlets. (SLD)

This study examined the effect of oral administration accommodations on test structure and student performance on the Reading test of the South Carolina High School Exit Examination (HSEE). The examination was given at Grade 10 and was untimed; hence, students were permitted as much time as they needed to answer all the questions. Three groups of…

This commentary on articles in this special issue generally agrees with the viewpoints expressed, although it argues that in some cases the authors of these articles should have expanded on certain issues. Many comments relate to the legal defensibility of the positions taken. (SLD)

Studied content domain, format, and level of inquiry as factors contributing to the large variation in student performance across open-ended measures. Results for more than 1,200 eighth graders do not support the hypothesis that tasks similar in content, format, and level of inquiry would correlate higher with each other than with measures…

The experience of the National Board for Professional Teaching Standards illustrates how issues of assessing the content representativeness of performance assessment can be addressed to ensure validity for certification procedures. Explores the challenges of collecting validation evidence when expert judgments of content are used. (SLD)
