A new vision of science learning described in the "Next Generation Science Standards"--particularly the science and engineering practices and their integration with content--pose significant challenges for large-scale assessment. This article explores what might be learned from advances in large-scale science assessment and…

This article proposes that sampling design effects have potentially huge unrecognized impacts on the results reported by large-scale district and state assessments in the United States. When design effects are unrecognized and unaccounted for they lead to underestimating the sampling error in item and test statistics. Underestimating the sampling…

This study investigated the application of multidimensional item response theory (IRT) models to validate test structure and dimensionality. Multiple content areas or domains within a single subject often exist in large-scale achievement tests. Such areas or domains may cause multidimensionality or local item dependence, which both violate the…

As states and provinces develop large-scale assessment programs linked to their curricula, teachers are increasingly expected to interpret the assessment results and to explain them to parents. The challenge for teachers is especially great in Ontario, which began developing an assessment program in 1996 after almost three decades without…

The National Education Association's Task Force on Testing has stated its opinion that standardized tests are overused. The task force suggests that the application of sampling techniques and a variety of alternatives to current testing practices would accomplish the same purposes. Representatives of the testing industry have indicated that the…

The New Hampshire statewide testing program was implemented to provide a data base for the evaluation of the effectiveness of Title I projects as required by Federal law. To accomplish this objective, achievement and intelligence tests were administered to children in Title I projects and regular programs in four elementary grades--2, 4, 6 and 8.…

Latent trait model calibration procedures were used on data obtained from a group testing program. The one-parameter model of Wright and Panchapakesan and the three-parameter logistic model of Wingersky, Wood, and Lord were selected for comparison. These models and their corresponding estimation procedures were compared, using actual and simulated…

The perceptions of testing directors, school principals, teacher supervisors, and classroom teachers concerning the actual purposes of public school standardized group testing programs were studied. Surveys were mailed to superintendents in 97 randomly selected public school districts. The superintendents forwarded survey packets to selected…
