It is only a slight exaggeration to describe the test theory that dominates educational measurement today as the application of twentieth-century statistics to nineteenth-century psychology. Sophisticated estimation procedures, new techniques for missing-data problems, and theoretical advances into latent-variable modeling have appeared--all…

Classical test theory, item response theory, and generalizability theory all treat the abilities to be measured as continuous variables, and the items of a test as independent probes of underlying continua. These models are well-suited to measuring the broad, diffuse traits of traditional differential psychology, but not for measuring the outcomes…

This book contrasts non-Soviet approaches to language testing and provides definitions from four Soviet language test experts. The role of foreign language teaching, the function of tests, and theoretical problems are discussed, with considerable focus on communicative competence. The book discusses test standardization and classification and…

From the fall of 1981 through June 1984, more than 850 disabled examinees took special administration of the Graduate Record Examinations (GRE). Grade point averages were obtained on 278 disabled students; 236 had enough complete data to be included in the study. Disabled students earned lower mean GRE scores than their nonhandicapped counterparts…

The effectiveness of the Chicago Mastery Learning Reading (CMLR) Program implemented in Ontario's Kettleby Public Schools (KPS) was measured by the students' reading progress and comparisons with the progress of other students in French immersion (FI) and other non-FI programs, including a gifted program. Within six months of CMLR implementation,…

Although perfectly scalable items rarely occur in practice, Guttman's concept of a scale has proved to be valuable to the development of measurement theory. If the score distribution is uniform and there is an equal number of items at each difficulty level, both the elements and the eigenvalues of the Pearson correlation matrix of dichotomous…

Standards, passing scores, or cut scores have been seen as an element of criterion-referenced tests since their introduction. This paper discusses at least two issues surrounding the establishment of cut scores which appear to need clarification: (1) the theoretical definition of a cut score; and (2) decisions which must be made in selecting a…

In spite of massive research efforts, no clear conclusions have been reached with regard to whether specific exceptional groups demonstrate Wechsler Intelligence Scale for Children-Revised (WISC-R) profiles that reliably differentiate them from normative or other exceptional groups. This study applied multivariate clustering and profile analysis…

Comments are made on the review papers presented by six Dutch psychometricians: Ivo Molenaar, Wim van der Linden, Ed Roskam, Arnold Van den Wollenberg, Gideon Mellenbergh, and Dato de Gruijter. Molenaar has embraced a pragmatic viewpoint on Bayesian methods, using both empirical and pure approaches to solve educational research problems. Molenaar…

Efforts to study the fidelity of translation of attitudinal scales into foreign languages have faltered due to the lack of powerful statistical tests to assess such transformations. This study uses a maximum likelihood factor analysis procedure to compare multivariate factor structures across subpopulations. The results showed that inconsistent…

This study used classical psychometric, latent trait, and nonparametric approaches to analyze 13- and 14-item scales of English language proficiency. Tests of English listening comprehension (dictation) and reading ("copytest") were constructed by modifying the standard dictation testing procedure to create items of text segments which…

Prompted by the increased use of behavior rating instruments in educational environments and evidence of confusion over the interpretation of labels designating behavior clusters, the present two-phase study analyzed 410 specific items contained in seven behavior rating instruments and investigated whether these items could be intuitively sorted…

This book discusses tricks for answering questions on the Law School Admission Test (LSAT). The tricks are based on an analysis of 12 editions of the LSAT which have been made public pursuant to New York's Truth in Testing Law. Sample LSAT questions published by the Law School Admission Council are referenced to exemplify the tricks' applications…

This book discusses tricks for answering questions on the Graduate Management Admission Test (GMAT). The tricks are based on an analysis of 20 editions of the GMAT which have been made public pursuant to New York's Truth in Testing Law. Sample GMAT questions published by the Graduate Management Admission Council are referenced to exemplify the…

Formula score theory (FST) associates each multiple choice test with a linear operator and expresses all of the real functions of item response theory as linear combinations of the operator's eigenfunctions. Hard measurement problems can then often be reformulated as easier, standard mathematical problems. For example, the problem of estimating…
