Both a standardized time limit and a differing time limit for certain groups is considered to demonstrate equity in treatment (fairness) in tests so long as the time limit does not impact the validity of the results. Fairness, in turn, in considered a fundamental validity issue in testing and assessments. Previous studies investigating the validity and equivalency of exam translation forms have not considered response time as a variable of interest. This study is an investigation into whether response time can vary enough across language forms to be considered a significant difference and whether that difference can impact the performance of test candidates. I analyzed these variables for an international professional credential that is translated to over a dozen languages. The findings support the hypothesis that response time can be significantly impacted by language. The credential that was analyzed for this study, however, allowed enough time that test candidate performance was not impacted by differences in response time. Additional studies should look into other assessments to determine if shorter time limits would cause performance differences due to response time differences by language.
