With the advent of big data and advances in technology, psychological assessments have become increasingly sophisticated and complex. Nevertheless, traditional psychometric issues concerning the validity, reliability, and measurement bias of such assessments remain fundamental in determining whether score inferences of human attributes are…

One of the areas subsumed under the data-based decision making and accountability practice identified in the National Association of School Psychologists' (NASP) "Model for Integrated School Psychological Services" is to collect information on psychological and educational variables to make decisions at a number of levels of service…

Reliability is a measure of consistency. It is the degree to which student results are the same when they take the same test on different occasions, when different scorers score the same item or task, and when different but equivalent tests are taken at the same time or at different times. Reliability is about making sure that different test forms…

This article introduces practitioners and researchers to the topic of missing data in the context of differential item functioning (DIF), reviews the current literature on the issue, discusses implications of the review, and offers suggestions for future research. A total of nine studies were reviewed. All of these studies determined what effect…

Differential item functioning (DIF) occurs when items on a test or questionnaire have different measurement properties for one group of people versus another, irrespective of group-mean differences on the construct. Methods for testing DIF require matching members of different groups on an estimate of the construct. Preferably, the estimate is…

Testing is one means of viewing differences among individuals. Culture is another means. When we mix testing and culture together, the results are fascinating and often confusing. Generally, we test individuals in an attempt either to serve them or reward them, and if we want to reward people, there is a strong desire and need to be fair. However,…

Court cases are presented that illustrate some of the issues that courts have dealt with in the area of educational testing. While this study was developed primarily for parents, the booklet should also help school administrators and testing professionals learn about court cases and precedents relevant to some major issues in educational testing.…

Gender, racial, and ethnic differences occur in vocational and cognitive ability assessments when the average scores of various groups are not equal. Results of such assessments indicate that not all groups are equally represented at all points of the assessment continuum. Many attempts to reduce or minimize existing group differences have been…

This article examines barriers to recognition of and assistance for gifted and talented Black students. Rationales for reexamining current theories and definitions are discussed and arguments made for broadening theories of giftedness to better include Black students. Suggestions are made for change and a list of considerations for educators…

This study used meta-analysis research techniques to determine if there are differences in General Aptitude Test Battery (GATB) validities and test scores between males and females. The sample consisted of 26,111 subjects from 122 Specific Aptitude Test Battery (SATB) validation or revalidation studies analyzed since 1972. Four approaches were…

Discusses the nature and sources of test bias in measuring communication skills. Recommends structured performance assessment to reduce bias, contending that performance tests, if carefully administered, can be valid, unbiased methods of assessing communication skills. (PD)

The article summarizes current knowledge as it relates to three basic requirements for assessment (qualified personnel, adequate tools, and fair implementation) and identifies research and evaluation priorities for special education and school psychology. Priorities include defining minimum competency for assessment personnel and identifying…

Three major areas (response mode, methods of presentation, and content) in which standardized assessment instruments can be modified to obtain objective information about the present abilities and/or future potential of severely handicapped students are discussed. (Author/SB)

Guidelines for test developers and users are provided to insure that construction and selection of test instruments are conducted fairly. In addition to development and selection, issues of interpretation of scores; provision of information to test takers; and prevention of test bias based on race, gender, or ethnicity are addressed. Twenty-one…

In the United States, standardized educational tests have been used for assessment purposes in grades K through 12 almost since the inception of the testing movement in the early 1900s. Because test-based assessment can have wide-ranging positive or negative effects on K-12 students, the test user must ensure that the tests used for assessment…
