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…

Two different measurement-evaluation systems (Precision Teaching and Data Based Program Modification) are contrasted in the following educational decisions: determination of the type of data to collect, use in assessment and determination of eligibility, monitoring student progress and modifying instructional programs, and determining overall…

A model of special education based on the use of a direct and repeated measurement and evaluation system for developing effective educational programs is described. Two separate studies are included, presenting student outcome data at both the individual and system level, for academic and social behaviors. (Author/CL)

A system-level analysis of the effectiveness of special education was conducted in an educational cooperative comprised of six school districts. In total, 96 students (grades 1-6) were assessed three times during the year on direct, curriculum-based measures of achievement in math, reading, and spelling. Analyses of student performance data were…

Eight direct scoring indices of written expression were intercorrelated, factor analyzed, and used to predict holistic judgments of writing samples of 172 middle-school students in compensatory/specialized education programs. Strongest predictors of holistic ratings were percentage of words correctly sequenced and percentage of correctly spelled…

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…

In this study, fourth-grade special education students (n=78) and general education students (n=403) took a large-scale statewide test using standard test administration procedure and two major accommodations addressing response conditions and test administration. On both reading and math tests, students bubbled in answers on a separate sheet (the…

The study examined the hypothesis that different evaluative interpretations of studies of special education effectiveness may be a function of the manner in which data are summarized and reported. Four metrics are compared including raw score, grade-equivalent score, z-score, and discrepancy index. Criteria for selecting metrics for program…

Ninety-one fourth grade students (from special education, Chapter 1, low achieving regular education, and regular education) completed a silent Dreading-written retell measure in the fall and again in the spring. Results highlight the many unanswered questions that need to be addressed in implementing assessment reform, in the areas of format,…
