G. Burket's criticisms regarding calculation and interpretation of group scores on norm-referenced tests are discussed. Burket and Baglin seem to agree on the existence of a problem in the calculation and interpretation of group scores on norm-referenced tests but disagree on the issue of that problem's causes and solutions. (TJH)

This response to the Baglin paper (1986) points out the fallacy in inferring that inappropriate scaling procedures cause apparent discrepancies between medians and means and between means calculated using different units. (LMO)

Article commented on a study by Harris, who presented formulas for the variance of errors of estimation (of a true score from an observed score) and the variance of errors of prediction (of an observed score from an observed score on a parallel test). (Author/RK)

While major test publishers randomly select school districts for their national norming studies, a survey of "accepting" and "declining" districts supports the hypothesis that self-selection bias results in overrepresentation of districts which already use a specific publisher's tests or instructional materials.

A structure for describing different approaches to testing is generated by identifying five dimensions along which tests differ: test uses, item generation, item revision, assessment of precision, and validation. These dimensions are used to profile tests of reading comprehension. Only norm-referenced achievement tests had an inference system…

Support for the validity of the equipercentile assumption is presented in contrast with the conclusion of Powers, Slaughter, and Helmick (EJ 289 091). Observed "gains" from pre- to posttests are better attributed to stakeholder bias, posttests that match curriculum content too closely, or a combination of these factors. (Author/DWH)

Norm-referenced standardized achievement tests are designed for obtaining group scores which can vary widely, depending on not only the measure of central tendency but also the type of derived score employed. This situation is hypothesized to be the result of using inappropriate statistical procedures to develop publishers' scaled scores.…

The Nedelsky procedure and two modified versions of the Ebel procedure were used by judges to set pass-fail levels on a medical certification examination in general surgery. Results indicated that the approaches produced different passing scores. The Ebel procedures displayed higher reliability than the Nedelsky approach. (Author/RD)

The Stanford Achievement Test Forms E and F were judged to be one of the best achievement batteries for assessing basic skills taught in grades one through nine. The test publisher provides several booklets in addition to the administration manual. These include the Norms Booklet, Handbook of Instructional Strategies, and Guide to Classroom…

In this paper, an attempt has been made to synthesize some of the current thinking in the area of criterion-referenced testing as well as to provide the beginning of an integration of theory and method for such testing. (Editor)

This article is a reply to a previous paper (see TM 500 488) interpreting Livingston's original article (see TM 500 487). (CK)

The 12 subtests of the Ball Aptitude Battery (BAB) listed in the administration manual were described. The reviewer believes this aptitude battery, designed for use with high school students and adults in job selection and placement, needs major improvements. It is suggested that the BAB be used solely for research purposes. (DWH)

In assessing the validity of a norm-referenced model used in evaluating large-scale federal educational programs for disadvantaged children, gain estimates were shown as approximately equal with randomized control group model estimates compared by retrospective analyses of two databases. (Author/CM)

Significantly more positive attitude toward subject matter of instruction was associated with the use of the criterion-referenced measure than with the norm-referenced measure; differences in attitude toward mode of instruction were not significant. (Author)
