When power tests include a time limit, it is important to assess the possibility of speededness for examinees. Past research on differential speededness has examined gender and ethnic subgroups in the United States on paper and pencil tests. When considering the needs of a global audience, research regarding different native language speakers is warranted. Data from a computerized adaptive test administered globally in English were used to compare different measures of time pressure and speed for 15 language groups compared to native-speaking English examinees. Results indicated that examinees whose native language was Korean had issues with speededness when many of the metrics were considered, but when test score was controlled, there were no relevant differences for any of the languages compared to English.
