The Early Fractions Test v2.2 is a paper-pencil test designed to measure mathematics achievement of third- and fourth-grade students in the domain of fractions. The purpose, or intended use, of the Early Fractions Test v2.2 is to serve as a measure of student outcomes in a randomized trial designed to estimate the effect of an educational…

The purpose of this study was to examine the impact of dimensionality, common-item set format, and different scale linking methods on preserving equity property with mixed-format test equating. Item response theory (IRT) true-score equating (TSE) and IRT observed-score equating (OSE) methods were used under common-item nonequivalent groups design.…

In early 2001, to support an internal evaluation of the impact of changing exclusion rates on reports of statistically significant gains across states, the National Center for Education Statistics (NCES) sponsored research on imputation procedures of National Assessment of Educational Progress (NAEP) scores for the excluded students and provided…

This study, third in a series using data from the National Education Longitudinal Study of 1988 (NELS:88), demonstrates the usefulness of multidimensional representation of mathematics achievement as it extends analyses through grade 12. Findings support a distinction between mathematical reasoning and knowledge for two of the three test forms.…

The goal of the current study was to examine the influence of providing more optimal testing conditions and evaluate the effect this has on the validity of the score inferences across ELL students with different needs, strengths, and levels of language proficiency. It was expected that the validity of the score inferences would be similar for 3rd…

The North Carolina Test of Algebra II was developed for use as an achievement test following the completion of the Algebra II course of study. Its design serves two purposes: (1) a normative measure of student achievement; and (2) an objective-based measurement of curriculum coverage. The test's curricular validity, content validity, instructional…

The Verbal, Mathematics, Academic, and General self-concept scales of the Self Description Questionnaire (SDQII) (H. Marsh, 1990, 1993) were translated into Chinese and administered to high school students in China (N=493). Item scale correlations and reliability coefficients were good (alphas=0.85, 0.91, 0.87, and 0.86 respectively). Confirmatory…

The KeyMath Revised is a power test that measures the understanding and application of mathematics skills and concepts. It is individually administered and is intended for students from kindergarten through the ninth grade to determine student mastery of mathematics concepts. The revised version is designed to be user-friendly for the student and…
