The chapters in this online volume comprise the TIMSS & PIRLS International Study Center's technical report of the methods and procedures used to develop, implement, and report the results of TIMSS 2019. There were various technical challenges because TIMSS 2019 was the initial phase of the transition to eTIMSS, with approximately half the…

This article reports the results of a study of potential sources of item nonequivalence between English and Chinese language versions of a cognitive development test for preschool-aged children. Items were flagged for potential nonequivalence through statistical and judgment-based procedures, and the relationship between flag status and item…

This article is based on an experiment designed to conduct an interpreting test for multiple candidates online, using web-based synchronous cyber classrooms. The test model was based on the accreditation test for Professional Interpreters produced by the National Accreditation Authority of Translators and Interpreters (NAATI) in Australia.…

When a test is adapted from a source language (SL) into a target language (TL), the two forms are usually not psychometrically equivalent. If linking between test forms is necessary, those items that have had their psychometric characteristics altered by the translation (differential item functioning [DIF] items) should be eliminated from the…

For a growing number of test translations, there is a need for equating that provides scores that can be used interchangeably for both source- and target-language forms, but basic equating requirements cannot usually be met in the cross-lingual case. The situation is more problematic in verbal tests, where translation has more impact on item…

The validity of results from international assessments depends on the correctness of the test translations. If the tests presented in one language are more or less difficult because of the manner in which they are translated, the validity of any interpretation of the results can be questioned. Many test translation methods exist in the literature,…

Test developers continue to struggle with the technical and logistical problems inherent in assessing achievement across different languages. Many testing programs offer separate language versions of a test to evaluate the achievement of examinees in different language groups. However, comparisons of individuals who took different language…

This study investigated the interaction between different cultural groups and item type, and the ensuing effect on construct validity for a psychological inventory, the Myers-Briggs Type Indicator (MBTI, Form G). The authors analyzed 94 items from 2 Chinese-translated versions of the MBTI (Form G) for factorial differences among groups of…

Often, educational and psychological measurement instruments must be translated from one language to another when they are administered to different cultural groups. The translation process often necessarily introduces measurement inequivalence. Therefore, an examination may be said to exhibit differential functioning if the test provides a…

Is it possible to translate an existing test from the source language to a target language and then to empirically link the translated test to the source language standard? Some tests are amenable to translation of their content and some are not. Within tests, some items may be translatable and others may not. Some items may measure meaningful…

Different methodologies for linking tests across languages are reviewed and evaluated, focusing on monolingual item response theory, bilingual group designs, and matched monolingual group designs. These methods, although not without weaknesses, are superior for promoting score comparability than methods that rely on translation or expert judgment…

Issues affecting measures that are translated or adapted from an initial language or culture to a new one are described. Notions of test validation, fairness, and norms are addressed, and it is argued that such adaptations may be necessary when assessing members of subpopulations of the U.S. culture. (SLD)

This paper describes the General Educational Development (GED) Testing Service's Spanish Test Adaptation Project. The GED Tests are designed to give those who have not graduated from high school the opportunity to earn a diploma that is recognized by institutions of higher education and employers. The purpose of this project is to develop, based…

A multi-year effort is being made to create a revised Spanish-language version of the Tests of General Educational Development (GED). It is necessary to ensure that the translated, adapted version maintains the same content and performance standards as the original English version. The final linking of the Spanish-language and English versions…

Translating achievement tests and questionnaires prepared in one language and culture for use in other languages and cultures has been a long-standing practice. Unfortunately, there is considerable technical evidence that suggests that the quality of test translations varies considerably, and too often the translations are not very good, thus…
