This manual was written to provide technical information regarding the General Educational Development (GED®) test as evidence that the GED® test is technically sound. Throughout this manual, documentation is provided regarding the development of the GED® test and data collection activities, as well as evidence of reliability and validity. This…

This article proposes that sampling design effects have potentially huge unrecognized impacts on the results reported by large-scale district and state assessments in the United States. When design effects are unrecognized and unaccounted for they lead to underestimating the sampling error in item and test statistics. Underestimating the sampling…

This paper presents the characteristics, properties and development of the National Reference Scale for reading. This new scale is the result of a reanalysis of the Anchor Test Study data using Rasch model procedures, in an effort to produce equated scores among all reading tests included in that study. (Author/JKS)

This study addresses the sample error and linking bias that occur with small and unrepresentative samples in a non-equivalent groups anchor test (NEAT) design. We propose a linking method called the "synthetic function," which is a weighted average of the identity function (the trivial equating function for forms that are known to be…

An asymptotic expression for the reliability of a linearly equated test is developed using normal theory. Reliability is expressed as the product of test reliability before equating and an adjustment term that is a function of the sample sizes used to estimate the linear equating transformation. The approach is illustrated. (SLD)

The adequacy of linking statewide standardized test results to the National Assessment of Educational Progress by using equipercentile equating procedures was investigated using statewide mathematics data from four states. Results suggest that the linkings are not sufficiently trustworthy to make comparisons based on the tails of the distribution.…

This paper deals with the problems that arise in performance assessment from the granularity that results from having a small number of tasks or prompts and raters of responses to these tasks or prompts. Two problems are discussed in detail: (1) achieving a satisfactory degree of reliability; and (2) equating or adjusting for differences of…

This digest is designed to provide information to Texas testing coordinators, other educators, and interested citizens about the development procedures and technical attributes of the state-mandated criterion-referenced assessment program. The chapters are: (1) "Background"; (2) "Test Development"; (3) "Test…

Although few question the positive impacts alternative forms of assessment can have on instruction, concerns about the psychometric quality of data obtained from such assessments are taking their toll. Scoring issues are at the heart of many of these concerns. This paper addresses the causes of these concerns: misinformation about psychometric…

This paper summarizes an investigation of applications and issues in free response (FR) testing during 1989. It draws on ideas from the results of the National Educational Longitudinal Study 1988 (NELS:88) field test, a seminar series at the Educational Testing Service (ETS), working papers prepared for several FR testing applications, and…

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.…
