"The Woodcock-Johnson IV Tests of Cognitive Abilities" (WJ IV COG) is an individually administered measure of psychometric intellectual abilities designed for ages 2 to 90+. The measure was published by Houghton Mifflin Harcourt-Riverside in 2014. Frederick Shrank, Kevin McGrew, and Nancy Mather are the authors. Richard Woodcock, the…

Computers can be used to score tests in order to reduce the workload of the teacher. (CK)

A computer program providing comprehensive test and item analysis is presented. Completing its performance on one run, the program, written in Fortran and emphasizing ease of use, integrates various statistical techniques for analyzing individual items and the overall test, in addition to generating a variety of standard scores.

Research performed pursuant to a U.S. Office of Education contract, OEC-5-10-154.

It has been argued that item variance and test variance are not necessary characteristics for criterion-referenced tests, although they are necessary for norm-referenced tests. This position is in error because it considers sample statistics as the criteria for evaluating items and tests. Within a particular sample, an item or test may have no…

Authors describe a measurement technique which processes item data so as to indicate logical relationships among items. (HB)

One of a series of reports on the International Project for the Evaluation of Educational Achievement (in Mathematics).

This study examines a common set of equating items for their appropriateness to both American and Canadian populations and, to determine the equations for converting scores from the verbal and mathematical scales of the 1971 form of the Canadian Scholastic Aptitude Test (the future standard continuing scales of the CSAT) to the corresponding…

When survey data are analyzed by computer, a codebook is necessary to show how raw scores are translated to computer-usable form. When data are tabulated by hand, the need for a codebook depends upon the number of respondents, the number and complexity of items, and the types of statistical manipulations required. During the process of coding,…

Empirical results are presented as regards the implementation of a latent-trait psychometric model by means of conditional maximum likelihood estimation. Items are scored polychotomously into varying numbers of nominal categories and the test and item characteristic curves and information functions are examined. It is concluded that scoring items…

The author suggests that a computer program be designed which not only computes item statistics, but also provides a running commetary in English to assist teachers in their analysis of test results. (PR)

Since all commonly used latent trait models assume a unidimensional test, the applicability of the procedure to obviously multidimensional tests is questionable. This paper presents the results of the application of latent trait, traditional, and factor analyses to a series of actual and hypothetical tests that vary in factoral complexity.…

A student questionnaire is presented that is designed to measure attitudes toward school, with subscales for attitudes towards self, other students, teachers, the principal, and the school in general: The Battle Student Attitude Scale. Attitudes are discussed briefly, telling what they are, how they develop, and what effect they may have on…

Recent harsh criticisms that educational and psychological tests are unfair and inadequate measures of the capabilities of minority, poverty, and other educationally alienated groups are discussed. The authors suggest that there are two main issues, the first scientific, the second ethical: (1) Is a test a valid measure of the characteristics it…
