Research on an interpretation technique (IT) for using the Pupil Item Response Record (PIRR) of the Iowa Tests of Basic Skills (ITBS) to actively involve students in their test interpretation was presented. The major concern of the study was to determine whether the IT had any impact on attitudes toward or knowledge about the ITBS. Students in…

This study investigated the effect of extended-time limits in terms of performance levels and score comparability for reading comprehension scores on the Iowa Tests of Basic Skills (ITBS). The first part of the study compared the average reading comprehension scores on the ITBS of 61 sixth-graders with learning disabilities and 397 non learning…

The purpose of this study was to examines the relationship between students' core knowledge and their achievement in mathematics and reading on the Iowa Test of Basic Skills. The study was based on E. D. Hirsch's theory that having a strong foundation of core knowledge in one grade is necessary for growth and the understanding of new and more…

This paper reports the results of a behavioral anchoring analysis of the Iowa Tests of Basic Skills (Form G, Level 12) vocabulary (41 items) and reading comprehension (56 items) tests. Subjects were 82 sixth-grade students enrolled at the Carterville (Illinois) Grade School. More specifically, a curriculum-referenced interpretation of the ability…

The Anchor Test Study provides a method for translating a pupil's score on any one of eight widely used standardized reading tests for Grades 4, 5, and 6 to a corresponding score of any of the other seven tests, as well as furnishing new nationally representative norms for each of the eight tests. In addition, the Study presents new estimates of…

Reliability and validity of "Degrees of Reading Power" test and "Iowa Tests of Basic Skills" reading comprehension and vocabulary tests were compared. Test scores, grades, and assigned reading levels of 191 fifth and sixth graders and 186 sixth and seventh graders in an eastern Iowa school district were used. Reliability and…

To determine if equal raw scores have the same "meaning" for students tested "in" and "out-of-level," four "out-of-level" grade groups who took the Vocabulary, Reading, and Mathematics Concepts subtests of the Iowa Tests of Basic Skills typically administered to fifth graders were compared to "in…

A study examined whether departmentalization affected the reading achievement of sixth-grade students attending a Chicago public school. A random sample of 30 students was chosen from a group of 53 who received instruction in a departmentalized program. A second random sample of 30 was selected from a total of 54 students who received instruction…

The purposes of this study were to compare student, school, and group average distributions of two standardized tests, the Iowa Tests of Basic Skills (ITBS) and Stanford 7 Plus Achievement Test, and examine the American College Testing Programs college entrance examinations (Grades 11-12). In addition to the student-school norm comparisons, ratios…

An assessment analysis was performed to determine whether sets of items designed to measure three different subskills of reading comprehension of the Iowa Tests of Basic Skills (ITBSs) did, in fact, distinguish among these subskills. The three major skills objectives were: (1) facts; (2) generalizations; and (3) inferences. Data from…

As part of an investigation of the appropriateness of the original Anchor Test Study equating results for black and Spanish-surnamed students, this Appendix lists the detailed results of the analyses for grade six, origanized by vocabulary, reading comprehension, and total reading scores. For each analysis, a two-page set of results is presented.…

In 1990-91, the second year of Alaska's statewide testing program, the Iowa Tests of Basic Skills was administered to 24,684 Alaskan public school students in grades 4, 6, and 8. The nationally normed achievement test covered reading, mathematics, and language arts. Most students in grades 6 and 8 scored above the 50th percentile in all subjects,…

This study compared the reliability and validity of two different measures of reading ability, the Degrees of Reading Power (DRP) and the Iowa Tests of Basic Skills (ITBS) Reading test and the ITBS Vocabulary test. The data consisted of scores of 377 grade 5 and grade 6 students on these tests, along with their assigned reading levels in the…
