In this technical report, the Center for Research Use in Education (CRUE) presents the methodological design of a large-scale quantitative investigation of research use by school-based practitioners through the "Survey of Evidence in Education for Schools (SEE-S)." It documents the major technical aspects of the development of SEE-S,…

High school graduation is "not yet a reliable indicator of college readiness", (Gaertner & McClarty, 2015, p2). As such, researchers are investigating the use of non-cognitive factors as predictors of College and Career Readiness (CCR). The College and Career Readiness Mathematical Practice Scale (CCRMS) was designed to measure…

Large numbers of young people in the United States were in foster care or in juvenile justice custody as teenagers, and many of them have a difficult time making a successful transition to independent adulthood as they leave these systems. Most of them faced a number of disadvantages during childhood and often have poor outcomes across several…

In preparation for online administration of the ACT® test, ACT conducted studies to examine the comparability of scores between online and paper administrations, including a timing study in fall 2013, a mode comparability study in spring 2014, and a second mode comparability study in spring 2015. This report presents major findings from these…

This technical report is one in a series of five describing the reliability (test/retest an alternate form) and G-Theory/D-Study on the easyCBM reading measures, grades 1-5. Data were gathered in the spring of 2011 from the convenience sample of students nested within classrooms at a medium-sized school district in the Pacific Northwest. Due to…

In this technical report, we describe the results of a study of mathematics items written to align with the Common Core State Standards (CCSS) in grades 6-8. In each grade, CCSS items were organized into forms, and the reliability of these forms was evaluated along with an experimental form including items aligned with the National Council of…

Previous studies have indicated that the reliability of test scores composed of testlets might be overestimated by conventional item-based reliability estimation methods (R. Thorndike, 1953; A. Anastasi, 1988; S. Sireci, D. Thissen, and H. Wainer, 1991; H. Wainer and D. Thissen, 1996). This study used generalizability theory to investigate the…

This study examined the generalizability of systematic direct observation across setting and time. Participants included 14 students from an intact inclusionary fifth grade classroom. On-task/off-task behavior was directly observed using momentary time-sampling recording, twice a day, for 10 school days. Using Generalizability (G) theory, results…

Not infrequently, investigators assume that reliability for groups is greater than reliability for persons, or that the error variance for groups is less than that for persons. Using generalizability theory, it is shown that this "conventional wisdom" is not necessarily true. Examples are provided from the course-evaluation and the…

Job analysis has played a fundamental role in developing and validating licensure and certification examinations, but research on what constitutes reliable and valid job analysis data is lacking. This paper examines the reliability and validity of job analysis survey results. Generalizability theory and the multi-facet Rasch item response theory…

This paper reports the results of generalizability theory (G) analyses done for new writing and speaking tasks for the Test of English as a Foreign Language (TOEFL). For writing, a special focus was placed on evaluating the impact on the reliability of the number of raters (or ratings) per essay (one or two) and the number of tasks (one, two, or…

This study examines the score dependability of writing and speaking assessments from the Test of English as a Foreign Language (TOEFL) from the perspectives of univariate and multivariate generalizability theory (G-theory) and presents the findings of three separate G-theory studies. For writing, the focus was on evaluating the impact on…
