Independent schools are, for the most part, exempt from mandatory participation in standardized tests designed for state and federal comparisons, nor are they required to take part in comparative international assessments. The anxiety in the broader culture, however, is driving a growing interest among independent school parents (and prospective…

The purpose of this study was to examine the effects of a controversial test administration alteration, the read-aloud alteration, in which text (passages and questions) is read aloud to the student on a reading comprehension test. For students whose disabilities impair their skill in decoding text and reading fluently, accessing text to…

The 2011 study, "Benefits of Practicing 4 = 2 + 2: Nontraditional Problem Formats Facilitate Children's Understanding of Mathematical Equivalence," examined the effects of addition practice using nontraditional problem formats on students' understanding of mathematical equivalence. In nontraditional problem formats, operations appear on…

The purpose of this article is to describe and demonstrate a three-step process of using differential distractor functioning (DDF) in a post hoc analysis to understand sources of differential item functioning (DIF) in multiple-choice testing. The process is demonstrated on two multiple-choice tests that used complex alternatives (e.g., "No…

A Markov chain Monte Carlo (MCMC) method and a bootstrap method were compared in the estimation of standard errors of item response theory (IRT) true score equating. Three test form relationships were examined: parallel, tau-equivalent, and congeneric. Data were simulated based on Reading Comprehension and Vocabulary tests of the Iowa Tests of…

Due to the problems inherent in using a norm-reference test such as the Iowa Test of Basic Skills (ITBS) to determine pupil achievement, a comparison of ITBS with the Individually Prescribed Instruction (IPI) continuum and placement tests was undertaken. This yielded the following conclusions: Of the 136 items on test 1-A Arithmetic Concepts, 14…

The major purpose of this study was to ascertain the reading and math progress made by Title I eligible intermediate grade students who lived and attended school in the Minneapolis Public Schools Target Area. A comparison group of students was also selected for study from a non-target school. The study population was all 1969-70 fourth graders…

This report examines the overlap between student test results on the Iowa Test of Basic Skills (ITBS) and the Washington Assessment of Student Learning (WASL). The two tests were compared and contrasted in terms of content and measurement philosophy, and analyses studied the statistical relationship between the ITBS and the WASL. The ITBS assesses…

A study examined the effect of geographic mobility on elementary school students' achievement. Although such mobility, which requires students to make multiple moves among schools, can have a negative impact on academic achievement, the hypothesis for the study was that it was not a determining factor in reading achievement test scores. Subjects…

The purpose of this study was to: (1) compare the book selection preferences of inner-city and suburban fourth and sixth grade children, and (2) determine if children consistently chose books according to categories of literature. Comparison of inner-city and suburban students of the same sex and reading level provided a control for sex and…

For several decades, the Iowa Tests of Basic Skills (ITBS) held the preeminent role in measuring student and school performance in the Chicago Public Schools (CPS), Illinois. In the context of the No Child Left Behind act and new calls for accountability, the CPS has decided to include results from the Illinois Standard Achievement Test (ISAT) in…

The Wichita Follow Through Project (Tucson Early Education Model) involved kindergarten through third grade pupils from low and middle income families in four elementary schools. The 1975-76 longitudinal evaluation was based primarily on results from the Iowa Tests of Basic Skills (grades three-six). Also included were the Metropolitan Readiness…

As part of its academic testing program and the evaluation of academic achievement, the Des Moines (Iowa) Public School System administers two standardized, norm-referenced achievement tests. These are the Iowa Tests of Basic Skills (ITBS) and the Iowa Tests of Educational Development (ITED). This document provides information regarding…

The Annual Test Report, 1981-82 has been developed as a reference on the results of the California Achievement Tests (CAT) in the Montgomery County Public Schools (MCPS). The report contains several analyses of the results from the CAT administration in Grades 3, 5, 8, and 11. Overall countywide results are presented and they are also broken down…

Academic achievement under a four-day school week is compared to the traditional five-day school week. Test scores from the CAT [California Achievement Test], ITBS [Iowa Test of Basic Skills], TASK [Stanford Test of Academic Skills], SAT [Stanford Achievement Test], TAP [Tests of Academic Proficiency], and MAT [Metropolitan Achievement Test] were…
