This study is an evaluation of the psychometric issues associated with estimating objective level scores, often referred to as "subscores." The article begins by introducing the concepts of reliability and validity for subscores from statewide achievement tests. These issues are discussed with reference to popular scaling techniques, classical…

Extended time is one of the most common testing accommodations provided to students with disabilities. It is also controversial; critics of extended time accommodations argue that extended time is used too readily, without concern for how it changes the skills measured by tests, leading to scores that cannot be compared fairly with those of other…

This report examines the availability and quality of predictive validity data for a selection of benchmark assessments identified by state and district personnel as in use within Mid-Atlantic Region jurisdictions. Based on a review of practices within the school districts in the region, this report details the benchmark assessments being used, in…

The usefulness of traditional concepts of validity and reliability, developed for large-scale assessments, for the classroom context is explored. Alternate frameworks that situate these constructs in teachers' work in classrooms are presented, and their use in an assessment course for preservice teachers is described. (SLD)

Political and legislative pressures have posed a number of measurement issues and challenges to the development of sound, valid voluntary national tests (VNTs). This paper focuses on what appear to be the most difficult technical issues related to the VNT proposed by President Clinton in 1997. Technical issues refer to psychometric issues, as…

Tests in social studies and integrated science given in Saint Vincent, Saint Lucia, Grenada, and Dominica were analyzed by the Organization for Co-operation in Overseas Development (OCOD) Comprehensive Teacher Training Program (CTTP) for discrimination, difficulty, and reliability, as well as other characteristics. There were 767 examinees for the…

The psychometric properties of the testing tools of the Michigan Educational Assessment Program (MEAP), the state standardized testing program, are examined. Reliability studies have indicated that the scores from the MEAP, ranging from 0.654 to 0.949, are generally acceptable. The State Department of Education offered supporting evidence for the…

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…

The North Carolina End-of-Grade Testing Program is based on the assessment of higher level skills in the context of specific subject-area content. These tests inform students, parents, the community, and educators about the achievement of North Carolina students in grades three through eight in given areas. This report describes the development…

In the spring of 1986, New York City began using the Metropolitan Achievement Test-6 (MAT-6) series to assess achievement in mathematics as part of a continuing end-of-year testing program. During the first two years of the program, appropriate levels of the shelf version of MAT-6 (Forms L and M) were administered to second through eighth graders.…

This study examined the psychometric characteristics of the Scholastic Aptitude Test (SAT) administered under special conditions for nine handicapped groups. Four psychometric characteristics were studied: level of test performance, test reliability, speededness, and extent of unexpected differential item performance. Psychometric comparisons were…

This bibliography provides abstracts of 28 recent (most were published since 1993) books, journal articles, and other documents concerned with testing accommodations for students with disabilities. The emphasis was on studies examining the effects of testing accommodations on the technical integrity of assessment measures. However, the…

The North Carolina End-of-Course Testing Program is based on the assessment of higher level skills in the context of specific subject-area content. These tests inform students, parents, the community, and educators about the achievement of North Carolina students in given areas. This report describes the development and psychometric properties of…

Computer-based testing (CBT) is typically implemented using one of three general test delivery models: (1) multiple fixed testing (MFT); (2) computer-adaptive testing (CAT); or (3) multistage testing (MSTs). This article reviews some of the real cost drivers associated with CBT implementation--focusing on item production costs, the costs…
