Pearson product-moment correlation coefficient between item g and test score X, known as item-test or item-total correlation ("Rit"), and item-rest correlation ("Rir") are two of the most used classical estimators for item discrimination power (IDP). Both "Rit" and "Rir" underestimate IDP caused by the…

Developmental score scales represent the performance of students along a continuum, where as students learn more they move higher along that continuum. Unidimensional item response theory (UIRT) vertical scaling has become a commonly used method to create developmental score scales. Research has shown that UIRT vertical scaling methods can be…

By applying multilevel models with random effects, the authors reviewed and synthesized findings from 30 studies that were published in the last 20 years exploring the relationship between the Educational Testing Service Major Field Test for a Bachelor's Degree in Business (MFTB) and related factors. The results suggest that MFTB scores correlated…

To investigate possible iPad related mode effect, we tested 403 8th graders in Indiana, Maryland, and New Jersey under three mode conditions through random assignment: a desktop computer, an iPad alone, and an iPad with an external keyboard. All students had used an iPad or computer for six months or longer. The 2-hour test included reading, math,…

States are increasingly interested in including measures of student achievement growth, or "value- added," in evaluating teachers. Annual state assessments, however, which are the typical measure of student growth, usually cover only reading and math teachers and only in grades 4-8. These state assessments thus cannot …

States and school districts are exploring alternatives to state tests for measuring teachers' contributions to student learning. One approach applies statistical value-added methods to alternative student assessments such as commercially available tests and end-of course tests. The evidence suggests that these methods can reliably distinguish…

In the arena of educational testing, accessibility refers to the degree to which students are given the opportunity to participate in and engage a test. Accessibility theory is a model for examining the interactions between the test-taker and the test itself and defining how they may decrease some students' access to the test event, ultimately…

Multiple-choice item-writing guideline research is in its infancy. Haladyna (2004) calls for a science of item-writing guideline research. The purpose of this study is to respond to such a call. The purpose of this study was to examine the impact of student ability and method for varying the location of correct answers in classroom multiple-choice…

Higher elementary student scores on standardized tests do not mean educational improvement. Scores can be affected by teaching "to" the test, coaching on test taking, and skewed norms. Test scores have been declining at the secondary level. Included is a discussion of secondary tests. (MD)

Declining test scores have been a major cause for concern in the past year. Describes the decline and explores some possible causes. (Editor/RK)

Two forms of a test of consumer competency, developed as valid, reliable, normed tests in consumer education, were given to Illinois public school students in grades 8-12. A comparison of mean scores indicated that students who had completed a consumer education course scored higher on both test forms than those who had not. Test results are shown…

The first edition of this book was written to give information about testing to people whose work gave them access to test results, but whose training included little or nothing about the use and interpretation of tests. Later editions have been intended for a broader audience as the need for understanding what test scores really mean has…

Claims that standards-based tests neither measure skills and knowledge accurately nor help educators do a better instructional job. The article offers suggestions in four areas to make the tests contribute to improved instruction: measurement of content standards; descriptions of standards; standard-by-standard reporting; and locally administered…

This guide--written for school administrators, teachers, counselors, parents, and the community--describes educational tests and measurements and test-related statistics. While specifically intended to help readers interpret the tests administered in the Los Angeles (California) Unified School District, this information may also be used to…

This guide is organized into five chapters; (1) an approach to testing--decisions made from test results, types of achievement tests, types and levels of objectives, and test validity, reliability, and practicality; (2) classroom test construction--planning, item banks, item writing, assembly, administration, and scoring; (3) test analysis-item…
