This study introduces the first Arabic Vocabulary Levels Test (Arabic-VLT), created for foreign learners of Arabic. We present compelling evidence to substantiate its validity and reliability. The Arabic-VLT was developed according to five levels, beginning with the most frequently used words (Level 1) to the least frequently used ones (Level 5),…

This guide is designed to help researchers make sure that their research reports include enough information about study measures so that readers can assess the quality of the study's methods and results. The guide also provides examples of write-ups about measures and suggests resources for learning more about these topics. The guide assumes…

Techniques derived from item response theory are useful for estimating the reliability of test classification above and below the cutting score. Test developers can construct a test whose information is peaked in the region of the cutting score; users can select a test which provides the most information in this region. The Cut-Score…

The importance of using the standard error of measurement (SEm) in determining reliability in test scores is emphasized. The SEm is compared to the hypothetical true score for standardized tests, and procedures for calculation of the SEm are explained. (JDD)

The stability of intelligence test scores over time was examined for the Wechsler Intelligence Scale for Children-Revised (WISC-R). Subjects included 64 children aged 6-16, who had been administered the WISC-R during prior evaluations. These students had been referred because of academic difficulties. One-third of the sample had taken the test…

This study explored whether standard administration and scoring of conventional articulation tests accurately identified 20 children (ages 5-9) as phonologically disordered and whether test data established severity levels and programing needs. Tests correctly identified the phonological disorders but failed to reliably differentiate severity…

This manual summarizes technical information regarding the 1982 Stanford Achievement Test, Seventh Edition when administered to hearing-impaired students. In Section 1, the procedures used to select the norming sample (7,557 hearing-impaired students) are described, and the demographic characteristics of the resulting sample are compared to those…

Interest in and use of the System of Multicultural Pluralistic Assessment's (SOMPA's) Health History Inventories (HHI) has been intensive despite the unavailability of psychometric data estimating its stability. This paper reports the results of a longitudinal study designed to provide data on the stability of the HHI over a four year period. The…

Reports that no significant difference in reliability appeared between a heterogeneous and a homogeneous form of the same general science matching-item test administered to 316 sixth-grade students but that scores on the heterogeneous form of the test were higher, independent of the examinee's sex or intelligence.

The Bracken Basic Concept Scale, for use with preschool and primary-aged children, determines a child's school readiness and knowledge of English-language verbal concepts. The instrument measures 258 basic concepts in such categories as comparisons, time, quantity, and letter identification. This paper describes test administration, scoring and…

This bulletin describes the technical adequacy of the Florida Teacher Certification Examination and includes discussions on establishing test reliability, test validity, passing scores, and protecting the test from cultural or ethnic bias. Chapter I describes the development of the examination: (1) development, identification, and validation of…

The Basic Achievement Skills Individual Screener is described as a quick screening tool for assessing basic skills of students functioning at grade 1-8 levels. The tool uses norm-referenced and criterion-referenced measures to assess achievement in reading, mathematics, spelling, and writing. This paper discusses test administration, scoring,…

This study is an attempt at a cohesive characterization of the concept of essay reliability. As such, it takes as a basic premise that previous and current practices in reporting reliability estimates for essay tests have certain shortcomings. The study provides an analysis of these shortcomings--partly to encourage a fuller understanding of the…

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…

This study validated computerized versions of selected tests from the Kit of Factor-Referenced Cognitive Tests of 1976, compared performance of higher education students on computerized and paper-and-pencil versions of the tests, and explored whether gender, academic status, or age interacted with the tests.
