Viable methods for the identification of item misfit or Differential Item Functioning (DIF) are central to scale construction and sound measurement. Many approaches rely on the derivation of a limiting distribution under the assumption that a certain model fits the data perfectly. Typical DIF assumptions such as the monotonicity and population…

Balancing assessment of learning outcomes with the expectations of students is a perennial challenge in education. Difficult exams, in which many students perform poorly, exacerbate this problem and can inspire a wide variety of interventions, such as a grading curve. However, addressing poor performance can sometimes distort or inflate grades and…

This article provides a single, common-case study of a test retrofit project at one Colombian university. It reports on how the test retrofit project was carried out and describes the different areas of language assessment literacy the project afforded local teacher stakeholders. This project was successful in that it modified the test constructs…

Multiple-choice retrieval practice with additional lures reduces retention on a later test (Roediger & Marsh, 2005). However, the mechanism underlying the negative outcomes with additional lures is poorly understood. Given that the positive outcomes of retrieval practice are associated with enhanced relational and item-specific processing…

Turkish and Foreign Languages Research and Application Center (TÖMER) is one of the important institutions for learning Turkish as a foreign language. In these institutions, proficiency tests are applied at the end of each level. However, test applications in TÖMERs vary between each center as there is no shared program in teaching Turkish as a…

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 paper aims to tell how the Russian national examination in mathematics (the Uniform State Examination or USE) has been conducted most recently. The author must say at once that the history of the system of secondary school graduation examinations or even the history of the USE will be covered only to the small degree that is necessary for…

Most experts in the testing community have presumed that the $350 million promised by the U.S. Department of Education to support common assessments would promote those that made greater use of open-ended items capable of measuring higher-order critical-thinking skills. But as measurement experts consider the multitude of possibilities for an…

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…

A method for detecting and interpreting disturbances of the local-independence assumption among items that share common stimulus material or other features is presented. Dichotomous and polytomous Rasch models are used to analyze structure of the learning outcome superitems. (SLD)

Rescoring of Center for Occupational and Professional Assessment objective-referenced tests is decided largely by content experts selected by client organizations. A few of the test items, statistically flagged for review, are not rescored. Some of this incongruence could be due to the use of the biserial correlation (r-biserial) as an…

The wording and structure of questionnaire items can interact with specified sample categories based on evaluation goals and respondent characteristics. The effects of the interactions can restructure samples and introduce bias into the data analysis. These effects, and suggestions for avoiding them, are demonstrated for five types of…

The literature on item bias, i.e., the question of whether some items in tests favor one cultural group over another cultural group due to irrelevant factors, is reviewed and evaluated. All known references through 1981 are described including a large number of unpublished reports. Each method is described and the criticisms that have appeared in…

A mathematics item on the Scholastic Aptitude Test (SAT) was found to be faulty and received wide publicity. A detailed investigation into its mathematical and psychometric properties is presented. It was found that the problem could be considered ambiguous but that almost no one noticed the ambiguity. (Author/JKS)

The Selected Marker Tests were examined for scoring problems and internal consistency and were administered orally to sixth and seventh graders. Scoring problems were discovered and changes were suggested. The problem was found to be item reliability rather than interrater reliability. (Author/MH)
