Daniel Koretz is the Henry Lee Shattuck Professor of Education at the Harvard Graduate School of Education. His research focuses on educational assessment and policy, particularly the effects of high-stakes testing on educational practice and the validity of score gains. He is the author of "Measuring Up: What Educational Testing Really Tells…

This study constitutes the secondary analysis of data collected as part of classroom instruction in a prior practitioner inquiry study. Consequently, IRB approval, parental consent, and participant assent for the present study were obtained after the conclusion of the original study.

A total of 19 graduate students enrolled in a graduate course conducted 6 consecutive administrations of the Wechsler Intelligence Scale for Children, 4th edition (WISC-IV, Canadian version). Test protocols were examined to obtain data describing the frequency of examiner errors, including administration and scoring errors. Results identified 511…

The 2011 NAEP-TIMSS linking study conducted by the National Center for Education Statistics (NCES) was designed to predict Trends in International Mathematics and Science Study (TIMSS) scores for the U.S. states that participated in 2011 National Assessment of Educational Progress (NAEP) mathematics and science assessment of eighth-grade students.…

This report examines the differences in impact estimates and standard errors that arise when these are derived using state achievement tests only (as pre-tests and post-tests), study-administered tests only, or some combination of state- and study-administered tests. State tests may yield different evaluation results relative to a test that is…

This study examined how much improvement was attainable with respect to accuracy of differential item functioning (DIF) measures and DIF detection rates in the Mantel-Haenszel procedure when employing focal and reference groups with notably unbalanced sample sizes where the focal group has a fixed small sample which does not satisfy the minimum…

This paper examines factors that influence the post-adoption satisfaction of educators with e-learning systems. Based on the expectation-confirmation framework, we propose a research model that demonstrates how post-adoption beliefs affect post-adoption satisfaction. The model was tested at a university by educators (n = 175) who use an e-learning…

To evaluate test speededness and to derive implications for test program activity, this study reviewed the literature on speed and power, identifying four major approaches to the assessment of speed: the Gulliksen approach, the Cronbach and Warrington approach, the Stafford approach, and the approach of the Educational Testing Service (ETS) as…

Despite its widespread use in evaluation data analysis, statistical testing has come under persistent criticism resulting in calls for its rethinking, and even possible elimination (Carver, 1978, 1993). Saxon and Boylan issue a call "to strengthen developmental education research and to make it more accessible" (2003, p. 2). Among the types of…

The National Assessment of Educational Progress (NAEP) currently tests seventeen-year-old students enrolled in public and private secondary schools, but it does not test "out-of-school" seventeen-year-olds who have either graduated or dropped out. Estimating that one of five seventeen-year-olds is out of school, the interpretability of…

This paper presents two examples of how methodological research in testing and evaluation simultaneously served the needs of both researchers and practitioners. The first example focuses on Center for the Study of Evaluation (CSE) research in writing assessment. This research investigated issues in domain definition, cognitive processing…

The National Assessment Governing Board and the National Center for Education Statistics sponsored a Joint Conference on Standard Setting for Large-Scale Assessments to provide a forum for technical and policy issues relevant to setting standards at local, state, and national levels. This executive summary conveys the essence of the conference by…

This report presents the results of a working meeting to provide guidance to staff at the National Center for Education Statistics on: (1) establishing guidelines for inclusion of limited-English-proficient (LEP) students in the National Assessment of Educational Progress (NAEP), field tests, research, and development; (2) modifications in the…

The research leading to the decisions to revise the Graduate Record Examination Aptitude Test (GRE) (beginning in October 1981) is reviewed. The issues discussed include the format of the test (the timing of each section and the number of sections, the content of the sections--especially the analytical section), the scoring procedure for the GRE,…

This report deals with ways to report basic skills test data which would facilitate the identification of student weaknesses. Under study are the technical aspects and methods associated with the reporting of objective-referenced data. An exploration is then made into the use of patterns of errors in responding to basic skills test items to…
