This paper examined the interaction between narrative performance, language exposure, and standardized measures of morphosyntax and semantics, in bilingual children tested two times, 1 year apart. We aimed to 1) identify the factor structure of oral narrative measures, and 2) examine the direction and strength of the effects of (i) language exposure and (ii) the relationship between language domains and narrative production. A total of 143 Spanish (L1)-English (L2) bilingual children completed a battery of oral narrative and oral language proficiency assessments in Spanish and English at two time points (kindergarten and Grade 1). Factor analyses yielded an identical two-factor structure of bilingual oral narrative measurements, namely productivity (word production) and complexity (sentence structure), in both Spanish and English across the two time points. Cross-lagged analysis showed that narrative production predicted semantics and morphosyntax performance in Spanish and English one year later. Cross-language transfer from L1 to L2 on the complexity of narrative was noted. Language exposure predicted only Spanish narrative production, but not English. These results suggest within- and cross-language transfer, highlighting the importance of L1 language development. In addition, current findings highlight the importance of language exposure for L1 in early school-age children.
