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)

A model for the validation of standardized tests of academic achievement upon populations not represented in the samples used to standardize the tests is presented, and the results of a field testing of the model are described. The 1973 editions of the Stanford Achievement Test and the Test of Academic Skills were administered to a sample of…

The Miller Assessment for Preschoolers, intended for children ages 2-5, is designed as both a screening and a diagnostic assessment, measuring neuromaturational variables, coordination, language, memory, problem solving, and visual perception. This review examines test administration, summation of data, standardization, reliability, and validity,…

This assessment of the usefulness of the "Wechsler Preschool and Primary Scale of Intelligence-Revised" and the "Wechsler Intelligence Scale for Children-Third Edition" for gifted children found that both are technically superior instruments with sensitive items, exceptional standardization, strong construct validity, and…

Comparison of college freshman performance on two different forms of the California Critical Thinking Skills Test (n=684, 692) found a lack of equivalence between forms and low internal consistency reliability. It is suggested that, although the test may be useful for research, it is not appropriate for decision making about individual students.…

Describes the process used to develop two examinations, an achievement test of computer literacy and a computer anxiety index. Highlights include a definition of computer literacy, determination of the validity and reliability of the tests, and a study to evaluate the final versions of the tests. (Author/LRW)

Rasch calibration procedures were applied to item-response data for the 1,262 infants and toddlers comprising the standardization sample for the Mental Scale of the Bayley Scales of Infant Development. Analyses tend to confirm the psychometric integrity of the instrument. (Author)

The Wechsler Individual Achievement Test assesses achievement in students in grades K-12, with subtests in reading, mathematics reasoning, spelling, reading comprehension, numerical operations, listening comprehension, oral expression, and written expression. The test was developed to assist in identification of students with learning…

The stability of annual normal curve equivalent (NCE) on the Iowa Test of Basic Skills over a period of six years was established in a previous study of status (position within a reference group). This study investigated the relationship between status stability and student achievement level. Third grade students in a suburban school district who…

The development and initial standardization of a two-part geography assessment test designed to measure student knowledge and understanding at the secondary level is the focus of this study. Intended to provide information about groups of students rather than to assess individual students, Part 1 of the test measures geographic skills and a…

This paper reports the development and testing of measures of teachers' attitudes toward testing and appropriate use of tests. A random sample of 555 practicing teachers in Wyoming were surveyed by mail (81 percent response rate). Five subscales assessing attitudes toward use of classroom and standardized tests were identified: (1) standardized…

Noting that reliable and valid measures of competence are essential for preschool screening, diagnostic, and research purposes, this review for practitioners and researchers presents an inventory and evaluation of standardized measuring instruments designed for assessing social and emotional competence in preschool children. A total of 39…

Assumptions have been made about the growth and development of reasoning and communicating skills in college. This study describes a standardized set of assessments of reasoning, writing and speaking with norms for freshmen and seniors and multiple equated forms. The study provides evidence of the validity and reliability of these assessments.…

This paper isolates and examines separately three distinct sources of error in essay scores: lack of agreement between raters; inconsistencies in performance within mode of discourse, and inconsistencies in performance between modes of discourse. Essay prompts in the Iowa Tests of Basic Skills (ITBS) Writing Supplement were designed to assess…

The study of curriculum-based measurement (CBM), involving 57 adults in a basic literacy program, found that narrative rather than expository passages exhibited higher reliability. Level of difficulty did not affect reliability. Validity data showed inconsistency between CBM and standardized test scores. The measures were sensitive to student…
