Previous research has shown that a crosslinguistic nonword repetition and narrative tasks can support the identification of developmental language disorder (DLD) in 5- and 6-year-old bilingual children. The tasks disentangled the effects of DLD and bilingualism and demonstrated good clinical validity. The present longitudinal study investigated whether similar results could be obtained at older ages by following the same children over a three-year period. The tasks were found to remain sensitive to DLD and insensitive to bilingualism. The magnitude of the effect of DLD decreased over time. Together, the instruments attained adequate diagnostic accuracy in a monolingual and bilingual group at each wave of testing, indicating that they can effectively identify DLD in different learning contexts and at different ages.
