In this article, the author updates his prior studies of LSAT® scores (Nieswiadomy 1998, 2006, 2010, 2014, 2017) using current data for 2022-23 law school applicants, finding that economics majors remain at or near the top of all applicants. Results of the previous studies showing economics majors scored well on the LSAT® have often been posted on…

We describe best practices in reporting reliability estimates in counseling research with consideration to precision, generalization, and diverse populations. We provide a historical context to reporting reliability estimates, the limitations of past practices, and new methods to address reliability generalization. We highlight best practices…

Quantile regression (QR) provides an alternative to linear regression (LR) that allows for the estimation of relationships across the distribution of an outcome. However, as highlighted in recent research on the motherhood penalty across the wage distribution, different procedures for conditional and unconditional quantile regression (CQR, UQR)…

Precisely estimating factor scores is challenging, especially when models are mis-specified. Stemming from network analysis, centrality measures offer an alternative approach to estimating the scores. Using a two-fold simulation design with varying availability of a priori theoretical knowledge, this study implemented hybrid centrality to estimate…

The present study investigates the influence of multidimensionality on linking and equating in a unidimensional IRT. Two hypothetical multidimensional scenarios are explored under a nonequivalent group common-item equating design. The first scenario examines test forms designed to measure multiple constructs, while the second scenario examines a…

This study examined the association between principal leadership styles and academic achievement in gifted education schools. There is scarce literature specific to academic achievement in gifted education schools. The primary research question addressed in the study was, "does an association exist between leadership style and academic…

Background: Hypertension (HTN) is a serious medical disease and the main cause of cardiovascular diseases and premature death worldwide. Purpose: The purpose of this study was to investigate the effectiveness of online mindfulness-based stress reduction (OMBSR) on systolic blood pressure (BP), diastolic blood pressure (BP), and heart rate (HR) in…

The purpose of this study is to introduce a method for converting scored 4-option multiple-choice (MC) items into scored 3-option MC items without re-pretesting the 3-option MC items. This study describes a six-step process for achieving this goal. Data from a professional credentialing exam was used in this study and the method was applied to 24…

A theoretical and conceptual framework for true-score equating using a simple-structure multidimensional item response theory (SS-MIRT) model is developed. A true-score equating method, referred to as the SS-MIRT true-score equating (SMT) procedure, also is developed. SS-MIRT has several advantages over other complex multidimensional item response…

One commonly used compromise standard-setting method is the Beuk (1984) method. A key assumption of the Beuk method is that the emphasis given to the pass rate and the percent correct ratings should be proportional to the extent that the panelists agree on their ratings. However, whether the slope of Beuk line reflects the emphasis that panelists…

In this research report, we describe a study to map the scores of the "TOEFL® Essentials"™ test to the Canadian Language Benchmarks (CLB). The TOEFL Essentials test is a four-skills assessment of foundational English language skills and communication abilities in academic and general (daily life) contexts. At the time of writing this…

There is increasing interest in using factor scores in structural equation models and there have been numerous methodological papers on the topic. Nevertheless, sum scores, which are computed from adding up item responses, continue to be ubiquitous in practice. It is therefore important to compare simulation results involving factor scores to…

Background: Learning to write the complex academic language (AL) associated with a discipline (like science) is a critical task in education, with middle school being a key developmental period. However, we need more research to guide how we assess students' learning to write AL, especially if we want to create assessment that guides more…

Learning programming has become increasingly popular, with learners from diverse backgrounds and experiences requiring different support. Programming-process analysis helps to identify solver types and needs for assistance. The study examined students' behavior patterns in programming among beginners and non-beginners to identify solver types,…

Dynamic testing, though underutilized, holds potential for assessing learning and instructional needs. However, its limited adoption is often attributed to the perceived time and labor-intensive nature of its administration. This study explores the viability of a training-only dynamic test (ToDT) with a standardized procedure to identify…
