This dissertation presents a comprehensive review of the evolution of DIF analysis within educational measurement from the 1980s to the present. The review elucidates the concept of DIF, particularly emphasizing the crucial role of grouping for exhibiting DIF. Then, the dissertation introduces an innovative modification to the newly developed…

This dissertation examines the landmark case Larry P. v. Riles and its impact on addressing the disproportionality and overrepresentation of Black and/or African American students in special education within California. Despite the court's ruling, which prohibited the use of IQ tests for Black students for special education placement due to…

This study addresses the underexplored terrain of conceptualizing and operationalizing race and ethnicity as grouping variables in Differential Item Functioning (DIF) studies within the context of psychometric research. The investigation extends beyond the identification of DIF and delves into the theoretical framing and communication of findings…

When developing a test, it is essential to ensure that the test is free of items with differential item functioning (DIF). DIF occurs when examinees of equal ability, but from different examinee subgroups, have different chances of getting the item correct. According to the multidimensional perspective, DIF occurs because the test measures more…

My dissertation examines three current challenges of international large-scale assessments (ILSAs) associated with the transition from linear testing to an adaptive testing design. ILSAs are important for making comparisons among populations and informing countries about the quality of their educational systems. ILSA's results inform policymakers…

Typical approaches to test and item development are rooted in the "Standards for Educational and Psychological Testing." Culturally responsive and antiracist assessment practices are two new processes that challenge the typical process noted in the "Standards," incorporating critical race theory and cultural responsiveness into…

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…

This three-article dissertation aims to address three methodological challenges to ensure comparability in educational research, including scale linking, test equating, and propensity score (PS) weighting. The first study intends to improve test scale comparability by evaluating the effect of six missing data handling approaches, including…

The zero-sum game of education is supported by the implementation standardized testing in a manner that disenfranchises Black students. While assessments are accountability tools for ensuring rigorous teaching and for measuring student learning, the impact of these tests on students' identity needs to be examined. The demands of a knowledge-based…

The decision for high-stakes exams to be a core part of the admission process has not been without controversy. Current literature on standardized tests has focused on the bias associated with high-stakes exams and how Black students have historically scored low on these tests. Insufficient research exists on how a post-affirmative action and…

As the accuracy of evaluations is important to teachers, it is essential to examine their perceptions about accuracy (Cho & Schunn, 2018; Plunkett & Dyson, 2018). Understanding teachers' perceptions of accuracy are significant because an evaluation system's effectiveness depends on the teachers' belief that it is accurate (Lewis, 2018;…

A court decision in California, Larry P. v. Riles (1979) case, ruled in favor of African American students who were disproportionately and wrongly placed in special education (E.M.R. -- educable mentally retarded) classes. Standardized intelligence tests were biased, discriminatory and failed to identify the academic need to support African…

Historically, psychological tests were assumed to be objective, culture-free, and generalizable to any racial/ethnic minorities or socio-cultural group, even though most tests were standardized, validated, and found reliable with samples consisting only of White, middle-class, English- speaking individuals (The Council of National Psychology…

Source-based writing, in which writers read or listen to academic content before writing, has been considered to better assess academic writing skills than independent writing tasks (Read, 1990; Weigle, 2004). Because scores resulting from ratings of test takers' source-based writing task responses are treated as indicators of their academic…

The present study explores the use of Student Evaluations of Teaching (SETs) within higher education institutions. In particular, bias associated with student ratings was explored in several ways. An experimental study design, using an advanced measurement framework was employed. Eight faculty participants from four ethnic-identity groups, and two…
