Aberrant behavior refers to any type of unusual behavior that would not be expected under normal circumstances. In educational and psychological testing, such behaviors have the potential to severely bias the aberrant examinee's test score while also jeopardizing the test scores of countless others. It is therefore crucial that aberrant examinees…

In educational tests, a group of questions related to a shared stimulus is called a testlet (e.g., a reading passage with multiple related questions). Use of testlets is very common in educational tests. Additionally, computerized adaptive testing (CAT) is a mode of testing where the test forms are created in real time tailoring to the test…

This dissertation was designed to provide current information on the job satisfaction and organizational commitment of those identifying as women of color working in offices of academic testing. Faced with systemic oppression due to race and gender, women of color have opted in to a profession that is viewed by some as a threat and barrier to the…

This dissertation aims to bridge the gap between validity theory and the practice of validation. The dissertation employs a three-article approach. Following the introduction in Chapter I, three independent manuscripts representing three empirical studies are presented (i.e., Chapters II - IV). Each chapter is a stand-alone publishable manuscript,…

Binary item response theory (IRT) models are widely used in educational testing data. These models are not perfect because they simplify the individual item responding process, ignore the differences among different response patterns, cannot handle multidimensionality that lay behind options within a single item, and cannot manage missing response…

This three-paper dissertation explores item cluster-based assessments, first in general as it relates to modeling, and then, specific issues surrounding a particular item cluster-based assessment designed. There should be a reasonable analogy between the structure of a psychometric model and the cognitive theory that the assessment is based upon.…

The present study explored the dimensionality of cognitive structure from two approaches. The first approach used a famous relation between Visual Spatial Working Memory (VSWM) and calculation to demonstrate the multidimensional item response analyses when true dimensions are unknown. The second approach explored the detectability of dimensions by…

Legislation leading to the mandating of accountability testing in schools was chronicled between the publication of "A Nation at Risk" (1983) to the conclusion of No Child Left Behind (2016). Involvement in education by the federal government increased throughout the educational legislation during this time period. The Omnibus Trade and…

Educational and psychological constructs are normally measured by multifaceted dimensions. The measured construct is defined and measured by a set of related subdomains. A bifactor model can accurately describe such data with both the measured construct and the related subdomains. However, a limitation of the bifactor model is the orthogonality…

Developmental score scales represent the performance of students along a continuum, where as students learn more they move higher along that continuum. Unidimensional item response theory (UIRT) vertical scaling has become a commonly used method to create developmental score scales. Research has shown that UIRT vertical scaling methods can be…

One of the fundamental problems in language testing is the lack of adequate generalizability between what a test is measuring and what fulfills the learners' real world language use needs. It is important to recognize that no matter how precise a test measures a construct, if the way that a construct is defined and the way that test tasks are…

The primary purpose of this study was to provide quantitative data on the use of released Texas Assessment of Knowledge and Skills (TAKS) exams as benchmark test instruments in a sample population. Teachers have expressed concern over "teaching to the test," especially with the use of benchmark testing. This study was specifically…

Conceptions are contextual. In the realm of education, conceptions of various constituent groups are often shaped over a period of a number of years during which time these groups have participated in educational endeavors. Specifically, conceptions of assessment are influenced by beliefs, actions, attitudes, understandings, and past experiences.…

Purpose: The purpose of this study was to examine the college-readiness rates of Black, Hispanic, White, and Asian graduates of public secondary schools in Texas using archival data from the Texas Education Agency Academic Excellence Indicator System. Data examined were the average ACT and SAT scores for the past 10 school years (i.e., 2001-2002…

Since the time of Sputnik, American educators and policymakers have recognized the need to raise expectations by increasing rigor in high schools across the United States. Copious studies attest to the fact that students who take Advanced Placement coursework experience success in college (Adelman, 1999; Camara, 2003; College Board, 2005;…
