Abstract	Elicited Imitation Tests (EITs) are commonly used in second language acquisition (SLA)/bilingualism research contexts to assess the general oral proficiency of study participants. While previous studies have provided valuable EIT construct-related validity evidence, some key gaps remain. This study uses an integrative data analysis to further probe the validity of the Korean EIT score interpretations by examining the performances of 318 Korean learners (198 second language, 79 foreign language, and 41 heritage) on the Korean EIT scored by five different raters. Expanding on previous EIT validation efforts, this study (a) examined both inter-rater reliability and differences in rater severity, (b) explored measurement bias across subpopulations of language learners, (c) identified relevant linguistic features which relate to item difficulty, and (d) provided a norm-referenced interpretation for Korean EIT scores. Overall, findings suggest that the Korean EIT can be used in diverse SLA/bilingualism research contexts, as it measures ability similarly across subgroups and raters. (As Provided).
