Adapting credentialing examinations for international uses involves translating tests for use in multiple languages. This paper explores methods for evaluating construct equivalence and item equivalence across different language versions of a test. These methods were applied to four different language versions (English, French, German, and Japanese) of a Microsoft certification examination with samples ranging from 1,329 to 2,000 examinees per test. Principal components analysis, multidimensional scaling, and confirmatory factor analysis of these data were conducted to evaluate construct equivalence. Detection of differential item functioning across languages was conducted using the standardized p-difference index. The results indicate that these procedures provide a great deal of information useful for evaluating test and item functioning across groups. Some differences in factor and dimension loadings across groups were noted, but a common, one-factor model fit the data well. Four items were flagged for differential item functioning across all groups. Suggestions for using these methods to evaluate translated tests are provided.
