A method for medical screening is adapted to differential item functioning (DIF). Its essential elements are explicit declarations of the level of DIF that is acceptable and of the loss function that quantifies the consequences of the two kinds of inappropriate classification of an item. Instead of a single level and a single function, sets of…

This article proposes that sampling design effects have potentially huge unrecognized impacts on the results reported by large-scale district and state assessments in the United States. When design effects are unrecognized and unaccounted for they lead to underestimating the sampling error in item and test statistics. Underestimating the sampling…

In the attempt to identify or prevent unfair tests, both quantitative analyses and logical evaluation are often used. For the most part, fairness evaluation is a pragmatic attempt at determining whether procedural or substantive due process has been accorded to either a group of test takers or an individual. In both the individual and comparative…

Comprehensive academic achievement tests are routinely used by school psychologists in psycho-educational assessment batteries to identify learning disabled students. A variety of assessment measures are used across age groups to determine if a discrepancy exists between academic achievement and intellectual functioning; however, among the most…

This report summarizes the findings of Jackson and Lahadern who used a revised form of the Student Opinion Poll (SOP) and a questionnaire to study the intercorrelations of attitudes and achievement. The study found that: (1) first graders have attitudes toward school work but these attitudes were not differentiated toward specific school subjects;…

A number of different ways of ascertaining whether or not a test measures the same thing in different cultures are examined. Methods range from some that are obvious and simple to those requiring statistical and psychological sophistication. Simpler methods include such things as having candidates "think aloud" and interviewing them about how they…

A debate concerning specific issues and the general usefulness of the Rasch latent trait test model is continued. Methods of estimation, necessary sample size, and the applicability of the model are discussed. (JKS)

This article suggests that mechanical application of Golden Rule-like procedures is inappropriate. The fundamental idea embodied in them, namely, that of taking issues of equity into account in test construction, may reasonably be done without doing violence to test validity. (JAZ)

Statements made in a previous article of this journal concerning the Rasch latent trait test model are questioned. Methods of estimation, necessary sample sizes, several formuli, and the general usefulness of the Rasch model are discussed. (JKS)

A series of studies on conceptual and design problems in competency-based measurements are explained. The concept of validity within the context of criterion-referenced measurement is reviewed. The authors believe validation should be viewed as a process rather than an end product. It is the process of marshalling evidence to support…

As a preliminary step in customizing the Stanford Achievement Test, a study was made to compare the test items at each level with the curriculum objectives of a Florida school district, classifying them as either matching, above or below grade level, or unmatching. Results are shown in table form. (TE)

The way in which diagnostic reading test scores were used in planning a remedial program is examined in this report. Among the topics discussed are the administration of a diagnostic test in 13 Irish schools; the organization of a remedial program for students identified as having severe reading problems; weaknesses of diagnostic tests currently…

This article presents a model that can be used by local school districts for reanalyzing standardized test results to obtain a more valid assessment of local learning objectives can be used to identify strengths/weaknesses of existing programs as well as individual students. (EGS)
