For the past decade, the accountability model associated with No Child Left Behind (NCLB) emphasized proficiency on end of year tests; with Every Student Succeeds Act (ESSA) the emphasis on proficiency within statewide testing programs, though now integrated with other measures of student learning, nevertheless remains a primary metric for…

A statistical model is proposed that describes the determination of an educational outcome variable as a nonlinear function of explanatory variables defined at different levels of a survey data hierarchy, such as students and classes. The theoretical and practical derivation of the model is discussed, and an example is given. (Author/BW)

The feasibility of using item response theory (IRT) as a psychometric model for the Graduate Record Examination (GRE) Aptitude Test was addressed by assessing the reasonableness of the assumptions of item response theory for GRE item types and examinee populations. Items from four forms and four administrations of the GRE Aptitude Test were…

The assertion that Model C is feasible for Elementary Secondary Education Act Title I evaluation, why it is feasible, and reasons why it is so seldom used are explained. Two assumptions must be made to use the special regression model. First, a strict cut-off must be used on the pretest to assign students to Title I and comparison groups. Second,…

The 1990 National Assessment of Educational Progress (NAEP) will mark the first time that state-level comparisons will be possible with NAEP data. The 1990 data will contain, as a trial component, state-level assessments of eighth graders in mathematics. Mathematics and reading comparisons for fourth graders will be added in 1992. Statistical…

The results of a study which used the regression discontinuity model in the analysis of criterion-referenced test data are presented and inherent drawbacks in the use of the regression discontinuity model with this type of data are discussed. The discussion is based on the results of an analysis of data collected in the Mesa, Arizona School…

Latent trait model calibration procedures were used on data obtained from a group testing program. The one-parameter model of Wright and Panchapakesan and the three-parameter logistic model of Wingersky, Wood, and Lord were selected for comparison. These models and their corresponding estimation procedures were compared, using actual and simulated…

This paper focuses on the questions which arise as test practitioners monitor score scales derived from latent trait theory. Large scale assessment programs are dynamic and constantly challenge the assumptions and limits of latent trait models. Even though testing programs evolve, test scores must remain reliable indicators of progress.…

TAILOR is a computer program that uses the implied orders concept as the basis for computerized adaptive testing. The basic characteristics of TAILOR, which does not involve pretesting, are reviewed here and two studies of it are reported. One is a Monte Carlo simulation based on the four-parameter Birnbaum model and the other uses a matrix of…

This report provides achievement information from the Philadelphia, Pa. Follow Through program in Mathematics and Reading for the five years, 1971-1972 through 1975-1976. The data are drawn from cross-sectional analyses, focusing primarily on mean score performance in Total Mathematics and Total Reading on city-wide tests. The principal findings…

The utility of the biomedical model of adjusted statistics is demonstrated. The model is recommended for use by educational researchers to randomize subjects for a more accurate estimate of school programs' success or failure when compared across classrooms or other units. (Author/MH)

Ten papers presented at the first annual meeting of the Georgia Educational Research Association describe the following topics in educational research: (1) development and evaluation of the Elementary Curriculum Development Program, which involves individualized instruction in grades K-8; (2) reliability of the eighth grade reading subscales on…
