A study to develop a short form of the Wechsler Intelligence Scale for Children-Revised (WISC-R) for the intellectually gifted showed the Vocabulary and Block Design comprise the best two-subtest short form. The Similarities, Vocabulary, Block Design, and Object Assembly tetrad could be most useful in time and reliability. (Author)

The Selected Marker Tests were examined for scoring problems and internal consistency and were administered orally to sixth and seventh graders. Scoring problems were discovered and changes were suggested. The problem was found to be item reliability rather than interrater reliability. (Author/MH)

The reliability of scores from four forms of the Test of English as a Foreign Language (TOEFL) was estimated using a hybrid item response theory model. It was found that there was very little difference between overall reliability when the testlet items were assumed to be independent and when their dependence was modeled. (Author/SLD)

Results are reported from a study that investigated the correspondence between two methods used to assess differential item functioning (test item bias). The study also explored the influence of sample size on the two procedures. Although agreement between the two procedures was generally good, the Rasch procedure was more reliable. (IAH)

The Achievement Anxiety Test's dimensionality was assessed using data from 378 university students. Analyses suggest the viability of a unidimensional construct, whose ability to provide extreme subject groups showing differences on other characteristics of academic achievement was assessed. Such a scale has potential for separating…

Psychometric analyses of data from 230 individuals yielded a 29-item 4-scale revision of the original 50-item 5-scale Mental Retardation Attitude Inventory. Results showed adequate item characteristics; adequate reliability and homogeneity; adequate reliability, homogeneity, specificity, and independence of the four scales; and initial validity…

Statistical analysis tools in language testing are described, chiefly classical test theory and item response theory. Computer software for statistical analysis is briefly reviewed and divided into three tiers: commonly available; statistical packages; and specialty software. (Author/VWL)

To meet the requirements of the No Child Left Behind Act, school districts and states must compile summary reports of the levels of student achievement in reading and mathematics. The levels are to be described in broad categories: "basic and below," "proficient," or "advanced." Educational units are given considerable latitude in defining the…

The Motor-Free Visual Perception Test: Third edition (MVPT-3; Colarusso & Hammill, 2003) purports to measure overall visual perceptual ability. Task responses require no motor ability, eliminating the effect of motor performance on the overall visual perception score. The test authors suggested that this MVPT-3 characteristic allows for its…

Technical characteristics of the Reading Essential Skill Screener--Preschool Version (RESS-P) were studied using four independent samples of boys and girls aged 3-5 years. A decision efficiency study (N = 91) resulted in a total predictive value (TPV) of .85 when compared with the criterion of teacher report/judgment of emerging literacy at-risk…

Technical characteristics of the Reading Essential Skills Screener-Elementary Version (RESS-E; B. T. Erford, G. Vitali, R. Haas, & R. R. Boykin, 1995) were studied using 4 independent samples of boys and girls between the ages of 6 and 8 years. Evidence of internal consistency, test-retest reliability, decision efficiency, factorial validity,…

This article describes the development of a measure of adult sleep quality: the Adult Sleep-Wake Scale (ADSWS). The ADSWS is a self-report pencil-and-paper measure of sleep quality consisting of five behavioral dimensions (Going to Bed, Falling Asleep, Maintaining Sleep, Reinitiating Sleep, and Returning to Wakefulness). Data were collected from…

The Test of Spoken English (TSE) is an internationally administered instrument for assessing nonnative speakers' proficiency in speaking English. The research foundation of the TSE examination described in its manual refers to two sources of variation other than the achievement being measured: interrater reliability and internal consistency.…

Modified Parallel Analysis (MPA) is a heuristic method for assessing "approximate unidimensionality" of item pools. It compares the second eigenvalue of the observed correlation matrix with the corresponding eigenvalue extracted from a "parallel" matrix generated by a unidimensional and locally independent model. Revised…

In the Spring 2003 issue of "Harvard Educational Review," Roy Freedle stated that the SAT® is both culturally and statistically biased, and he proposed a solution to ameliorate this bias. His claims, which garnered national attention, were based on serious errors in his analysis. We begin our analyses by assessing the psychometric…
