Students with significant disabilities must participate in large-scale assessments, often using an alternate assessment judged against alternate achievement standards. The development and administration of this type of assessment must necessarily balance meaningful participation with accurate measurement. In this study, generalizability theory is…

This study describes validation data for qualitative and quantitative writing measures useful with a full range of students, including special education students, in grades three through five. The study looked for consistent administration and scoring, sensitivity in differentiating groups of students, relation to other accepted assessments, and…

This monograph reviews issues in research on the effects of using accommodations for students with disabilities who are included in educational assessments, particularly state and district assessments. Following an introductory overview, a section provides background on the need for good research on accommodations. The paper then defines commonly…

A series of standardized tasks was developed using the same constructs as operationalized in a state's large-scale assessment program. Student performance (n=437) was then analyzed. In reading and math, teachers (n=131) were successfully trained to administer the tasks and judge performance, providing a system with instructional and evaluative…

Seventh-grade science students (n=22) wrote prompted essays, compare-contrast essays, and traditional end-of-chapter criterion-referenced tests. Results indicated that essay tests may be highly sensitive to instructional content and prompt design, and the validity of essays as measures of content learning relates more to goals of instruction than…

Four alternate versions of a 15-item general outcome measure (GOM) of mathematics conceptual understanding and applications were developed and administered to 117 eighth-graders. Results were correlated with scores on state multiple-choice mathematics achievement tests. Correlations ranged from .81 to .87 with no significant differences, offering…

The reliability, sensitivity, and criterion-related validity of concept comparison (CC) ratings and computer-derived multidimensional scaling (MDS) maps were studied as ways of assessing reading comprehension. Fifteen experts (2 district coordinators and 13 reading specialists/special education teachers) were included in this study. Reliability…

This document summarizes the research on test changes to provide an empirical basis for defining accommodations for students with disabilities. It begins by providing an historical overview of special education accountability. It describes how separate special education accountability systems have evolved and summarizes information on the…

A survey of 166 regular and special-education teachers concerning allowable accommodations on statewide assessment tests found only 21% reported that they used allowed accommodations. Teachers' knowledge of allowable accommodations was low and suggests some students are unnecessarily exempted from participation. Results support preservice and…

Focus groups were used to examine the needs of students taking a computer adaptive math assessment. The assessment designed using universal design and item response theory. Focus groups included teachers, administrators, child advocacy groups, and 3rd grade students and parents from the following groups: students with disabilities, students in…
