The "Standards for Educational and Psychological Testing" of the American Educational Research Association, the American Psychological Association, and the National Council on Measurement in Education are intended to provide a comprehensive basis for evaluating tests. This digest identifies key standards applicable to most test…

The Wechsler Intelligence Scale for Children-Third Edition (WISC-III) is an individually administered test of intelligence for assessing children aged 6 through 16 years, 11 months. The WISC-III consists of several subtests, each classified into a verbal or performance scale. The child's performance on these measures is summarized in three…

A method is presented for determining the content validity of a series of secondary school mathematics tests. These tests are part of the Mathematics Diagnostic Testing Project (MDTP), a collaborative effort by California university systems to develop placement examinations and a means to document student preparation in mathematics. Content…

Assessing complex teaching performance in the National Board of Professional Teaching Standards (NBPTS) has caused the Educational Testing Service to wrestle with fundamental scoring issues that are both conceptual and technical. This report reviews the challenges encountered, how they are being addressed, and what the NBPTS effort has learned…

A "high-stakes" test can directly and powerfully influence how teachers teach and students learn. Six principles that describe the negative consequences of measurement-driven instruction are discussed, and the effect of these consequences on student and teacher behavior, as well as the test itself, is outlined. (IAH)

This paper offers a scenario for how educational assessment might change in response to market forces that affect not only the future of large-scale testing but also society in general. The scenario divides into three generations distinguished by the purpose of testing, test format and content, and the extent to which testing capitalizes on new…

A study was conducted to provide empirical evidence to answer the question of whether student scores on standardized achievement tests represent reasonable measures of instructional quality. Using a research protocol designed by W. Popham and the local study directors, individual test items from a nationally marketed standardized achievement test…

Results are presented from a study of portfolio use for large-scale assessment in the Pittsburgh (Pennsylvania) public schools that are more encouraging for the use of this form of assessment than many other studies have been. Requirements for the psychometric integrity of portfolio assessment are discussed. (SLD)

Psychometrically linking a state criterion-referenced test (CRT) and a norm-referenced test (NRT) to yield NRT information through the CRT was studied with samples of 1,500 to 3,000 elementary school students per subject and grade level in Connecticut. A CRT/NRT link can create a focused and coherent assessment system. (SLD)

The theoretical background, organization, performance subtests (object assembly, geometric design, block design, mazes, picture completion, and animal pegs), verbal subtests (information, comprehension, arithmetic, vocabulary, similarities, and sentences), reliability, validity (factor analysis), interpretation, advantages, and limitations of the…

Most seasoned test developers recognize the importance of thoughtful decision making when constructing a test. Unfortunately, many classroom achievement tests are created by novice test developed who have not received sufficient instruction in item writing (G. Gulliksen, 1986; R. J. Stiggins, 1991). The result is often a test that is poorly…

This handbook has been written for college teachers regardless of their prior training in pedagogy, assessment, or education. It is a practical handbook, designed for easy reference. Part 1 can provide either an introduction to Classroom Assessment or a comprehensive review, depending on the reader's prior experience. The first chapter explains…

For several decades, the Iowa Tests of Basic Skills (ITBS) held the preeminent role in measuring student and school performance in the Chicago Public Schools (CPS), Illinois. In the context of the No Child Left Behind act and new calls for accountability, the CPS has decided to include results from the Illinois Standard Achievement Test (ISAT) in…

Tests can be categorized into two major groups: norm-referenced tests (NRTs) and criterion-referenced tests (CRTs). NRTs are designed to highlight achievement differences between and among students to produce a dependable rank order of students across a continuum of achievement from high achievers to low achievers. With NRTs, a representative…

Norm-referenced tests (NRT) help compare the performance of one student with the performances of a large group of students, while criterion-referenced tests (CRT) focus on "what test takers can do and what they know, not how they compare to others" (Anastasi, 1988). Both types of test can be standardized so that scores can be interpreted the same…
