In international large-scale assessments, students may not be compelled to answer every test item: a student can decide to skip a seemingly difficult item or may drop out before the end of the test is reached. The way these missing responses are treated will affect the estimation of the item difficulty and student ability, and ultimately affect…

In educational assessments two types of missing responses can be discerned: items can be "not reached" or "skipped". Both types of omissions may be related to the test taker's proficiency, resulting in non-ignorable missingness. This paper proposes to model not reached and skipped items as part of the response process, using…

When dealing with missing responses, two types of omissions can be discerned: items can be skipped or not reached by the test taker. When the occurrence of these omissions is related to the proficiency process the missingness is nonignorable. The purpose of this article is to present a tree-based IRT framework for modeling responses and omissions…

Assessing the achievement of students in elementary and secondary schools and the nation's educational progress is fundamental to informing education policy approaches. Congressional interest in this area includes and extends beyond the annual assessments administered by states to comply with the educational accountability requirements of Title…

In July 2010, the Massachusetts Board of Elementary and Secondary Education (BESE) voted to adopt Common Core's standards in English language arts (ELA) and mathematics in place of the state's own standards in these two subjects. The vote was based largely on recommendations by Commissioner of Education Mitchell Chester and then Secretary of…

Recently, educational researchers and practitioners have turned to value-added models to evaluate teacher performance. Although value-added estimates depend on the assessment used to measure student achievement, the importance of outcome selection has received scant attention in the literature. Using data from a large, urban school district, I…

Analysis of comparisons of subtest scores of 76 students (grades two - six) on the Peabody Individual Achievement Test and the Woodcock Reading Mastery Tests revealed that, although correlations for the total group were highly significant in both comparisons, a grade level analysis demonstrated wide variability in results.

More than 50,000 New York City special education students in self-contained classes and resource rooms in grades 2-9 were tested in reading on the California Achievement Test, Form C. Students who had testing modifications recommended on their individualized education programs were tested with the appropriate modification. Among the moderately…

In April 1974, allegations were made that students, teachers, and the general public had access to the New York Citywide Reading Test prior to its administration, and the results, therefore, were invalid. In the face of these allegations, New York City developed a strategy for the administration of a secure test: a test never before available in…

The extent and direction of curriculum bias in standardized reading achievement tests were examined. (Author)

Specific suggestions and guidelines are presented for modifying psychological tests so that they can be used to obtain results that are not distorted by the individual's handicap. Focus is on testing persons with sight, hearing, and academic problems with the indication that principles developed for this fairly high percentage of the severely…

The purpose of this study was to explore the usefulness of the Rasch test analysis model for providing consistent scale statistics between content-referenced and norm-referenced tests across school districts. A number of content-referenced tests were created to assess student performance relative to basic skills goals identified in reading and…

Scores from the Stanford Achievement Tests administered to 50,000 students in Palm Beach County, Florida, were studied in order to determine whether the speeded nature of the reading comprehension subtest was related to inconsistencies in the score profiles. Specifically, the probable effect of random guessing was examined. Reading scores were…

The study reported in this paper examined whether a disproportionate number of boys and girls in a given grade level at various schools might have an inequitable effect on the mean achievement test scores of those schools. The student population of the Palm Beach County Schools, Florida, reflecting a cross-section of socio-economic backgrounds,…

The accountability movement in American education has received great clamors of attention in the past few years. This movement, in turn, suggests the need for particular data to inform responsible decision-making; the need for assessment instruments which can address the question of what is learned; and the need for strengthening the existing…
