Research on the development of reading skills in bilingual students suggests that reading skills develop interdependently across languages. The current study examined the effects of a French reading fluency intervention on the French and English reading skills of three Grade 3 students attending a French immersion program using a concurrent multiple baseline across participants single-case design. Results indicate that the intervention produced improvements in French reading fluency on instructional passages during intervention sessions and generalized improvements in English reading fluency skills. These findings provide additional support for the transferability of reading skills across languages.
