In large-scale assessments, such as state-wide testing programs, national sample-based assessments, and international comparative studies, there are many steps involved in the measurement and reporting of student achievement. There are always sources of inaccuracies in each of the steps. It is of interest to identify the source and magnitude of…

The collection of verbal reports is one way in which cognitive and developmental psychologists gather data to formulate and corroborate models of problem solving. The current use of verbal reports to design and validate educational assessments reflects the growing trend to fuse cognitive psychological research and educational measurement. However,…

Developmental standard score scales produce unrealistic expectations for growth of low-achieving students only if the low-achieving students are tested in an inappropriate way. Examples illustrate the unrealistic nature of such score scales when applied to the testing of learning disabled and Chapter One students. (SLD)

The increased use of test scores as a measure of school quality is discussed. Legitimate and illegitimate practices of test preparation are considered. Some commercial test preparation programs are reviewed, with some conclusions about their effectiveness and desirability. (SLD)

Some unfinished issues relating to achievement test theory that seemed implicit in the basic idea of criterion-referenced testing are reviewed, recognizing their importance in current studies of authentic assessment and performance-based tests. The future of performance-based evaluation is explored. (SLD)

In comparing the annual growth of low-achieving students and high-achieving students who remain at the same percentile rank, educators must choose between the properties of developmental standard scores and grade equivalents. The growth patterns for grade equivalent scores may be more reasonable than those for standard score scales. (SLD)

In their discussion of problems related to identifying learning disabilities with individually administered achievement tests, Phillips and Clarizio incorrectly conclude that developmental standard score scales produce unrealistic expectations for the growth of low-achieving students. By definition, these scores state how much the norm group's…

The documented decline in test scores of the 1960s and 1970s and the unclear picture since then result from educational and noneducational factors. Aspects of the misuse of test scores are (1) simplistic interpretation of performance trends; (2) unsupported evaluations of schooling; and (3) a reductionist view of education. (SLD)
