While curriculum-based measurement (CBM) tools for screening decisions in reading, mathematics, and written language have been well examined, tools for use in content areas (e.g., science and social studies) remain in the beginning stages of research. In this study, two alternate forms of a new CBM tool (Statement Verification for Science; SV-S),…

Assessing students' emerging literacy skills is crucial for identifying areas where a child may be falling behind and can lead directly to an increased chance of reading success. The Waterford Assessment of Core Skills (WACS), a computerized adaptive test of early literacy for students in prekindergarten through 2nd grade, addresses this need.…

This report provides a description of the development process, field testing, and psychometric properties of a student mathematics test designed to assess grades 1 and 2 student abilities. The test was administered to 2,373 participating grade 1 and 2 students in 22 schools located in 2 public school districts in Florida during fall 2013. Focused…

The technical adequacy of curriculum-based measures in the form of short and simple vocabulary-matching probes to predict students' performance and progress in science at the secondary level was investigated. Participants were 198 seventh-grade students from 10 science classrooms. Curriculum-based measurements (CBM) were 5-min vocabulary-matching…

A SERIES OF STUDIES SOUGHT TO ASCERTAIN (1) INTER- AND INTRA-RATER RELIABILITY FOR THE HARRIS-GOODENOUGH DRAW-A-MAN TEST, (2) DRAW-A-MAN (DAM) VALIDITY, AND DRAW-A-WOMAN (DAW) VALIDITY. THE DRAWINGS OF 72 STUDENTS IN AN UPPER MIDDLE CLASS WERE SCORED INDEPENDENTLY BY TWO SELF-TAUGHT SCORERS, ONE OF WHOM ALSO RESCORED THE TEST A WEEK LATER. THE…

Because of limitations in simple gain scores, pychometrists have proposed alternate methods for measuring change, two of which are residualized difference and base-free change. This paper provides large sample empirical estimates of the reliability these change measures. It checks theoretical predictions derived from inequalities involving all…

The effects of students taking different levels of the same standardized achievement test were assessed by administering two levels of the same test to each student. The functional level of the test was taken by all students. The second level of testing was randomly assigned at the adjacent higher or lower level of the test. Functional level…

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…

Results of the Vocabulary, Reading Comprehension, and Mathematics Concepts subtests of the Iowa Tests of Basic Skills were analyzed for sex bias. On the whole, little evidence for sex bias was found for the four subtests and three grade levels examined. (Author)

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…

The authors argue that personnel who select standardized achievement tests have been led to believe that the major achievement test batteries differ very little in terms of the topics they test; but that the content covered by these major tests is different, and that such differences have consequences for instructional content. To test this…

This paper isolates and examines separately three distinct sources of error in essay scores: lack of agreement between raters; inconsistencies in performance within mode of discourse, and inconsistencies in performance between modes of discourse. Essay prompts in the Iowa Tests of Basic Skills (ITBS) Writing Supplement were designed to assess…

Factor analysis was used to summarize the interrelationships between a large and varied collection of measures. Data for 500 third grade students assigned to either an experimental or a comparison condition were obtained. The data covered scores for the first 28 items of the Student Affective Behavior Checklist, (2) 9 nonmathematics subtests of…

Old Order Amish are readily distinguishable from others in society by their dissociation from "modern" convenience and dress. Students in an Old Order Amish school in Iowa receive instruction in language arts from a secular basal language arts workbook, and a basal reader containing biblical stories. Comprehension of content is evaluated…

This study attempts to determine the extent to which performance on educational tests is dependent upon language proficiency. Three questions are involved: (1) Will the dictation and the cloze tests prove to be as successful in distinguishing degrees of proficiency among native speakers as among second language learners? (2) How well will scores…
