Two studies using similar methods in two states investigated the long-term predictive utility of two single-skill early numeracy Curriculum Based Measures (CBMs) and the degree to which they can adequately predict high-stakes test scores. Data were drawn from kindergarten and first-grade students. State standardized assessment data from the…

Recent research in the area of Curriculum-Based Measures (CBM) in writing has shown that traditionally used metrics, such as total words written and total words correct, may not be the best tools for measuring writing performance, for both secondary and elementary aged children (e.g., Gansle, Noell, VanDerHeyden, Naquin, & Slider, 2002; Tindal…

This study focused on the predictive validity of fluency measures that comprise Dynamic Indicators of Basic Early Literacy Skills (DIBELS). Data were gathered from first through third graders attending 44 schools in 9 districts or local educational agencies that made up the first Reading First cohort in Michigan. Students were administered DIBELS…

A longitudinal study determined if children's invented spelling served as a viable predictor of reading achievement and compared the predictive value of assessing children's invented spelling relative to other notable predictors, such as letter names, letter sounds, a concept of a word, and phonemic awareness. Subjects, 52 kindergarten children…

The reliability and predictive validity of the WISC-R was investigated with 46 Mexican-American children. Approximately a year and a half after the administration of the WISC-R, scores on the Iowa Tests of Basic Skills were collected. Results indicated that the WISC-R meets minimum requirements of reliability and predictive validity with…

This study compared the validity of chronological age, a standardized algebra prognosis test, standardized verbal and quantitative scales derived from an achievement test battery, and an objective measure of formal or concrete stages of Piagetian cognitive development for predicting final examination scores and course grades in high school…

This study investigated the relationship between achievement test scores on the Iowa Tests of Basic Skills (ITBS) and Iowa Tests of Educational Development (ITED), and high school and college grade point average. Support for the predictive validity of the ITBS and ITED achievement test batteries is provided. (Author/GK)

Correlations between the achievement test scores of 2,000 entering freshmen in 1977 and measures of college performance were similar to those reported for tests of the college entrance type. These results provide support for the predictive validity of the Iowa Tests of Basic Skills and the Iowa Tests of Educational Development achievement test…

The predictive validity of the California Achievement Test, Reading (CAT-R) was examined for 480 Hispanic and Anglo pupils in Grades 2 and 3. The validity of the CAT-R as a predictor for reading for combined groups of Hispanic and Anglo pupils appeared to be limited. (Author/LMO)

The relationship was investigated between test scores obtained from the Iowa Tests of Basic Skills (ITBS) and the Iowa Tests of Educational Development (ITED), and the grade point average (GPA) at the high school and college level. The data used were unique in providing a longitudinal comparison of college students' performance with the results of…

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)

Stepwise regression was used in 1986 and 1987 to determine the best predictor variables for predicting the percentage of students in the 113 Atlanta Public Schools scoring at or above the national norm in reading and mathematics on the Iowa Tests of Basic Skills/Tests of Achievement and Proficiency. Twenty elementary school, 16 middle school, and…

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…

Forty-two pairs of experienced and novice teachers predicted the rank order of their pupils' scores on the reading and mathematics portions of the Iowa Test of Basic Skills (ITBS). The pool of novice teachers were first semester students in the Arizona State University Professional Teacher Preparation Program (PTPP). The experienced teachers in…

Thirteen of the 41 classroom observation dimensions derived from Medley's review of teacher effectiveness reports were scored on the Georgia Assessment of Teacher Effectiveness. Subjects were 53 fifth and sixth grade teachers in language arts and mathematics. The dimensions were: large group instruction; group size without adult supervision;…
