This longitudinal study investigated the predictors of word reading in English and French for 69 children in early total French immersion from first through third grade. The influence of phonological awareness, orthographic processing, and vocabulary in English and French on the achievement and growth of word reading in the 2 languages were evaluated with growth curve analyses. Findings revealed that predictors in Grade 1 were similar for English and French word reading in Grade 3. Specifically, English phonological awareness and orthographic processing predicted English word reading achievement; English orthographic processing also predicted growth in English word reading. French phonological awareness and orthographic processing in Grade 1 predicted French word reading achievement in Grade 3. Furthermore, at-risk readers identified in Grade 1 (n = 6) generally fell behind their typically developing peers across all measures, although evidence of improvement emerged over time.
