Popis: In order is meet the requiremcnts for technically sound assessment instruments as required by the No Child Left Behind Act of 2001 (NCLB), this study investigates the construct validity of Indiana's alternate assessment, the Indiana Standards Tool for Alternate Reporting (ISTAR), a teacher rating assessment as compared to Indiana's general educational assessment, the Indiana Statewide Test of Educational Progress - Plus (ISTEP+), a criterion referenced assessment. Study participants consisted of 284 students from grades 3, 6, and 8. Students were from general and special education. All students in the study were considered not to have significant cognitive disabilities that would have exempted them from ISTEP+ participation. Therefore, all students in the study were required to participate in the fall 2003 ISTEP+ testing session. Students with disabilities in the study were identified as having one of four mild disabilities as defined by the Indiana Professional Standards Board (Mild Mental Disabilities, Learning Disabilities, Emotional Disabilities, or Other Health Impairment. Teachers rated students using the ISTAR assessment during a fall testing window from August 1, through October 31, 2003. The Pearson correlation coefficient used to determine the relationship between ISTEP+ scores and ISTAR teacher ratings. Results of the Pearson correlation coefficient indicated a linear relationship between scores on the two assessment instruments for students in grades 3, 6, and 8 with mild disabilities and without disabilities who participated in both assessments (r = .46 to r = .71). An analysis of variance was used to determine if the ISTAR instrument could, when appropriately completed, differentiate between groups of students who would be expected to perform less well or better than other groups of students. Results from the ANOVA, Levene and Welch procedures as well as the Tamhane post hoc statistic indicated that ISTAR is capable of differentiating between different achievement level groups for the constructs of English/language arts and mathematics. While the study results indicate a sufficient positive relationship, it should be considered to be a baseline study. Additional years of data are needed before valid inferences can be made for the ISTAR assessment tool.
