Educators and researchers strive to build policies and practices on data and evidence, especially on academic achievement scores. When assessment scores are inaccurate for specific student populations or when scores are inappropriately used, even data-driven decisions will be misinformed. To maximize the impact of the research-practice-policy…

A common belief is that the Bookmark method is a cognitively simpler standard-setting method than the modified Angoff method. However, a limited amount of research has investigated panelist's ability to perform well the Bookmark method, and whether some of the challenges panelists face with the Angoff method may also be present in the Bookmark…

Traditional methods for examining differential item functioning (DIF) in polytomously scored test items yield a single item-level index of DIF and thus provide no information concerning which score levels are implicated in the DIF effect. To address this limitation of DIF methodology, the framework of differential step functioning (DSF) has…

Issues concerning the selection of judges for standard setting are discussed. Determining the consistency of judges' recommendations, or their congruity with other expert recommendations, would help in selection. Enough judges must be chosen to allow estimation of recommendations by an entire population of judges. (SLD)

Results of a 1987 report indicating that elementary students of all states were above the national average are assessed. Issues addressed include teaching for standardized tests, the effect of teaching on national norms, and alternatives available to protect the integrity of instruction and the validity of normed test scores.

In 1987, a survey report by J. Cannell was published criticizing state reports based on national standardized testing of elementary school students that indicated that all 50 states were above the national average. This phenomenon--known as the "Lake Wobegon Effect"--is analyzed. Technical problems with the study are considered. (TJH)

Results of a 1987 report--indicating that elementary students of all 50 states were above the national average--were assessed via 2 national mail and telephone surveys. Although results of data for 35 states support the general findings of the 1987 report, it appears that more specific results are less sensational. (TJH)

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)
