Language interventions may yield greater benefits for younger children than their older counterparts, making it critical to evaluate children's language skills as early as possible. Yet, assessing young children's language presents many challenges, such as limited attention spans, low expressive language, and hesitancy to speak with an unfamiliar examiner. To address these challenges, the Quick Interactive Language Screener for Toddlers (QUILS:TOD; for children 24- to 36-months of age) was developed as a quick, tablet-based language screener capable of assessing children's vocabulary, syntax, and word learning skills. We explored how children's performance on the QUILS:TOD and the MacArthur-Bates Communicative Development Inventory, another language screener, at two years of age relates to their performance one year later on the Quick Interactive Language Screener (QUILS), a validated and normed screener for children between three and six years of age. Results revealed that performance on the QUILS:TOD was predictive of QUILS performance, highlighting the utility of the QUILS:TOD for identifying which children at age two would continue to lag behind their peers at age three. Lastly, although all QUILS:TOD areas (vocabulary, syntax, and word learning) were predictive of QUILS performance, the most robust predictor of children's performance on the same receptive language dimensions at 3 years was their syntax, emphasizing the necessity of evaluating language beyond vocabulary.
