Huynh (1976) suggested a method of approximating the reliability coefficient of a mastery test. The present study examines the accuracy of Huynh's approximation and also describes a computationally simpler approximation which appears to be generally more accurate than the former. (Author/RL)

A number of different definitions and indices of reliability for mastery tests have recently been proposed in an attempt to cope with possible lack of score variability that attenuates traditional coefficients. One promising index that has been suggested is the proportion of students in a group that are consistently assigned to the same mastery…

Two statistical characteristics of the Matching Familiar Figures test which produce methodological problems in reflection-impulsivity research are discussed. (BRT)

This article is concerned with estimation of components of maximum generalizability in multifacet experimental designs involving multiple dependent measures. An example of a two-facet partially nested design is provided. (Author/RC)

Describes the procedures the authors of the System for Career Decision-Making (CDM) followed in establishing client scoring reliability. Authors recommend that manuals of self-scored inventories provide data establishing scorer reliability, that scoring be supervised, and that APGA test standards deal directly with scorer reliability. (Author)

Presented is a detailed description of two true score confidence interval approaches, their use, interpretation, and a philosophical conflict that arises in many applied instances. (Contains 27 references.) (Author)

Examined temporal stability of Wechsler Intelligence Scale for Children-Revised (WISC-R) for adolescents (N=155) identified as either educable mentally retarded (EMR) or learning disabled (LD). Found three major scales of WISC-R to be more stable over three-year period for LD than for EMR group, while subtest scales for EMR group showed greater…

The main purpose of the study was to investigate the distinctness and reliability of analytic (or multitrait) rating dimensions and their relationships to holistic scores and "e-rater"® essay feature variables in the context of the TOEFL® computer-based test (CBT) writing assessment. Data analyzed in the study were analytic and holistic…

Background: Research has shown that early identification of children with language issues is critical for effective intervention, and yet many children are not identified until school age. The use of parent-completed rating scales, especially in urban, minority populations, might improve early identification if parent ratings are found to be…

This study investigates the Test of English as a Foreign Language (TOEFL), in particular the relative contributions to score dependability (analogous to classical theory reliability) of various numbers of items and subtests as well as the decision dependability at different cut points. Research questions that apply to the overall TOEFL battery and…

Investigated with 129 kindergarten children were test-retest reliability and validity of the Developmental Test of Visual Perception (DTVP), and changes in factorial relationships among the five DTVP subtest after a 10-week use of the program of M. Frostig. (MC)

Data from 2-, 3-, 6-, and 7-point rating scales were analyzed to determine whether scale length affected response patterns. Results indicate that data configurations are relatively invariant with changes in number of scale points. (Author)

Based on dissertation for EdD degree at University of Texas (1966).

Seventeen statistics for measuring the reliability of criterion-referenced tests were critically reviewed. The review was organized into two sections: (1) a discussion of preliminary considerations to provide a foundation for choosing the appropriate category of "reliability" (threshold loss function, squared-error loss-function, or…

The Starkweather Social Conformity Test is a research instrument designed to measure conforming and nonconforming behavior by providing the young child with opportunities to make choices in a situation in which he can follow a model or respond freely according to his own preferences. The test discriminates between compulsive conformists or…
