Research has consistently shown that principal leadership matters for successful schools. Evaluating principals on the behaviors shown to improve student learning should be an important leverage point for raising leadership quality. Yet principals are often evaluated with the use of instruments with no theoretical background and little, if any,…

Both the attenuation paradox of traditional test theory and the assumption of local independence in person-item response theory have caused problems in interpretation. This paper demonstrates that the two are related concepts, and, through this demonstration, both are clarified. It is demonstrated that the breakdown of local independence leads to…

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…

One form of adaptive testing involves a two-stage procedure. The first stage is the administration of a routing test. From this first test, an estimate of an examinee's ability is obtained. On the basis of this ability estimate, a second test focused on a given ability level is administered. The purpose of this study was to compare the efficiency…

Guidelines for the construction and use of an attitude instrument are presented, and the application of the instrument to measure student attitude toward economics is described. Attention is directed to the Likert-like summated forced-choice variety of attitude instrument, whereby attitude toward the object is inferred from the summed responses to…

The purpose of this study is to examine an option-weighting method as it affects pass-fail decisions in formative and summative evaluation of student achievement for instructional units, certification, advancement, licensure, admissions, placement, and selection. A database was constructed using high school achievement test data where a…

Concern for enhancing construct validity of vocational interest measures provides a focus for scale construction quite distinct from that derived from a criterion-referenced strategy: Construct-oriented measurement implies: (1) substantive definitions of dimensions; (2) concern for internal consistency reliability, as well as generalizability; (3)…

Describes a paper-and-pencil test for high school biology students measuring science process skills, such as developing hypotheses; making predictions; identifying assumptions; analyzing data; and formulating conclusions. Reports some data on reliability and validity of the test. Provides all 35 items of the test. (YP)

In this paper 45 item-writing rules for multiple-choice tests presented in textbooks on educational measurement in a previous study are identified. The current study presents a quantitative review of the literature with respect to the empirical and theoretical evaluation of these principles of item-writing. Fifty-six studies that addressed at…

The objectives for this study were to: (1) develop a valid, reliable measure of test-wiseness with equivalent forms for use with students in the health sciences; and (2) determine the level of test-wiseness of entering medical students. The test-wiseness areas included in this study were: similar options, umbrella term, item give-away, convergence…

Despite the popularity of both multiple-choice (MC) and true-false (TF) items, most investigations comparing the two formats have done so to determine the optimum number of choices to be given to students within a given time period. The purpose of this investigation was to compare the reliabilities and the validities of both formats when the items…

Extended caution indices (ECI) specify the degree of confidence that can be placed in an individual's test score by analyzing patterns of item response. Among the most promising of such indices are the standardized ECIs. Contrary to the literature, several instances were found, in a previous study, of nonnormal distributions of ECIs with samples…

Order Analysis is a multidimensional scaling (MDS) technique for determining order among items. This paper reviews articles by different authors describing various components of ordering theory. A common nomenclature is constructed to link together the various ideas and is applied to a fairly simple set of data. Topics discussed include a more…

This study analyzed user manuals and technical supplements of 27 aptitude and achievement tests to determine whether disabled children were included in development of the tests' norms, items, reliability indices, and validity indices. Most test developers provided scant evidence that their tests were valid for use with disabled students. (JDD)

This report describes the development, construction, and validation of the Preliminary Chinese Proficiency Test (Pre-CPT), a standardized, nationally-normed test of listening and reading comprehension for beginning-level native English-speaking learners of Chinese as a second language. The Pre-CPT was designed as a lower-level version of the…
