Background: School feeding programs' evaluation requires the measurement of food insecurity, a more objective indicator, within school in low-income countries. The Global Child Nutrition Foundation (GCNF) uses subjective indicators to report school feeding coverage rates across many countries that participate in the global survey of school meal…

Item response theory (IRT) has so many advantages than its precedent Classical Test Theory (CTT) such as non-changing item parameters, ability parameter estimations free from the items. However, in order to get these advantages, some assumptions should be met and they are; unidimensionality, normality and local independence. However, it is not…

Interpreting and creating graphs plays a critical role in scientific practice. The K-12 Next Generation Science Standards call for students to use graphs for scientific modeling, reasoning, and communication. To measure progress on this dimension, we need valid and reliable measures of graph understanding in science. In this research, we designed…

Background: Validity is a central concern in any assessment, though this has often not been made explicit in the UK assessment context. This article applies current validity theorising, largely derived from American formulations, to national curriculum assessments in England. Purpose: The aim is to consider validity arguments in relation to the…

There has been little discussion of two conventions common within classroom assessment: the convention of representing student's performance on an assessment using a single score; and the convention of using the average score to summarize a student's performance over a set of assessments. This paper attempts to demonstrate that the assumptions…

In the reporting of individual student results from standardized tests in educational assessments, the percentile rank of the individual student is a major numerical indicator. This paper develops a formulation and presents calculations to examine the accuracy of the individual percentile rank score. Here, accuracy follows the common-sense…

Describes a procedure for rescaling objective measures of comprehension so that they reflect amounts of accuracy of comprehension on an absolute scale. Suggests there is adequate empirical evidence supporting the validity of the rauding rescaling procedure. (RS)

Discusses the exact meaning and limitations of commonly used types of standardized test scores: grade equivalent scores; percentile ranks, and standard scores. (SR)

A monograph issue on the development and use of a prescriptive measurement method is introduced. Given such a measurement system, it is possible to investigate both level and pattern of a student's performance, and to diagnose specific gaps in learning. (LMO)

In the reporting of individual student results from standardized tests in educational assessments, the percentile rank of the individual student is a major numerical indicator. For example, in the 1998 and 1999 California Standardized Testing and Reporting (STAR) program using the Stanford Achievement Test Series, Ninth Edition, Form T (Stanford…

Examined the validity of data generated by the School Readiness for Reforms: Leader Questionnaire using an iterative procedure that combined classical and Rasch rating scale analysis for the analysis of responses from 167 leaders. The combined approach yielded comprehensive diagnostic information on the quality of the instrument's five subscales.…

The aim of this paper is to explore the Rasch model as a criterion of test homogeneity. Two empirical studies are presented to demonstrate this usage. From these studies it is argued that statistical tests of item characteristic curve (ICC) slopes are not sufficient in testing for heterogeneity. Tests of equality of ICC's over groups of subject…

The career of Stuart Appleton Courtis in the growth of testing and educational measurement parallels the development of progressive education in the first half of the twentieth century. In 1909 he developed the standardized Courtis Arithmetic Test, Series A, the first objective test used in any city public schools. Continuing his work in testing,…

Examines relationships among tests for numerosity, measurement, and computational estimation, and recognizes tests for numerical facility and quantitative reasoning using principal components analysis. Identifies two components. The first component aligned computational estimation with numerical facility and general quantitative reasoning while…

Described are procedures followed in developing, administering, and scoring a set of mathematical problem-solving superitems and examining their construct validity through a recently developed evaluation technique associated with a taxonomy of the structure of learned outcomes. Data strongly support the validity of the underlying theoretical…
