This report summarizes some of the evidence supporting interpretations of scores from the enhanced ACT, focusing on reliability, concurrent validity, predictive validity, and score comparability. The authors argue that the evidence presented in this report supports the interpretation of scores from the enhanced ACT as measures of high school…

Amid profound changes to student placement systems at universities and colleges, the placement of English language learners has remained largely the same. Generally speaking, international students, and in some places other English language learners, face single measure testing and required remediation. Single measure high stakes testing goes…

This study examined the psychometric proprieties of the Arabic version of the Curriculum-Based Measurement Oral Reading Fluency (CBM ORF) for Jordanian students. A sample of 200 students (six to eight years old) was recruited from four public primary schools in Jordan. Results indicated that the CBM ORF had adequate reliability and validity…

Test providers are increasingly moving toward exclusively administering assessments by computer. Computerized testing is becoming more desirable for test takers because of increased opportunities to test, faster turnaround of individual scores, or perhaps other factors, offering potential benefits for those who may be struggling to pass licensure…

The Dental Aptitude Test (DAT) in Canada and the Dental Admission Test (DAT) in the United States are discussed. A history of the DAT, its composition, underlying concepts, and the problems of validation and guidelines for its uses are presented. A review of the literature is provided. (Author/MLW)

Previous research has studied the effects of different methods of item option weighting on the reliability and concurrent and predictive validity of achievement tests. Increases in reliability are generally found, but with mixed results for validity. Several methods of producing option weights, (i.e., Guttman internal and external weights and…

The Kuder Richardson-20 Formula is shown to be a special case, where each examinee is given sufficient time to answer each item, of a more general formula where each examinee may not be allowed the necessary time. The formula is extended to allow two scores, knowledge and speed, to be extracted from each examinees test score. Using a sample of 82…

This study determined how accurately high school students (n= 1119) report class rank on the Student Descriptive Questionnaire (SDQ). Official transcripts were analyzed to determine which rank category should have been reported by each applicant. The authors concluded students report their rank in class with a fairly high degree of accuracy.…

Presented at the Annual National Council on Measurement in Education (NCME) in New York in March 2008. This presentation explores how different item weighting can affect the effective weights, validity coefficents and test reliability of composite scores among test takers.

Two types of student response inventories for appraising instruction, the Student Instruction Report (SIR) and the Inventory of Student Perceptions of Instruction (ISPI) were administered to 554 students in 30 classes at two Georgia colleges. Mean responses to items were used in principal components analyses with varimax rotation. The two…

The predictive validity of the Comparative Guidance and Placement Program (CGP) tests for two diverse curricular groups was examined. Three methods for developing predictive equations were compared. The CGP was administered to 417 Liberal Studies and 316 Business Technical students at a New England community college. Principal component analyses…
