Tracing Student Responsiveness to Intervention With Early Literacy Skills Indicators: Do They Reflect Growth Toward Text Reading Outcomes?

Latent Class Growth Trajectories of Letter Name Knowledge During Pre-Kindergarten and Kindergarten

A major developmental task for young children in the United States involves the acquisition of knowledge about the letters in the English alphabet. In the current study, we examined the growth trajectories of children's letter name knowledge (LNK) during pre-kindergarten and kindergarten. A diverse sample of 1,015 children was drawn from the National Center for Early Development and Learning Multi-State Study of Pre-Kindergarten. Latent class growth analyses were used to identify three heterogeneous classes of children based on their LNK growth trajectories. Children's fall-of-pre-kindergarten language skills were associated with trajectory class membership, which in turn was associated with children's spring-of-kindergarten literacy skills. We also found that the association between children's fall-of-pre-kindergarten language skills and spring-of-kindergarten literacy skills was partially mediated by trajectory class membership. These findings point to the importance of LNK skill development as a marker variable to monitor and support children's emergent literacy development.

Advancing Stage 2 Research on Measures for Monitoring Kindergarten Reading Progress

Although several measures exist for frequently monitoring early reading progress, little research has specifically investigated their technical properties when administered on a frequent basis with kindergarten students. In this study, kindergarten students ( N = 137) of whom the majority was receiving supplemental intervention for reading skills were monitored using Letter Sound Fluency, Phoneme Segmentation Fluency, Word Reading Fluency, Nonsense Word Fluency, Highly Decodable Passages, and Spelling on a biweekly basis between February and May. Acceptable reliability was observed for all measures. Analyses of slope validity using latent growth models, latent change score models, and slope differences according to level of year-end achievement indicated that the relation of slope to overall reading skills varied across the measures. A suggested approach to kindergarten students' reading progress is offered that includes Letter Sound Fluency and a measure of word-reading skills to provide a comprehensive picture of student growth toward important year-end reading outcomes.
