This study investigated the effectiveness of a supplemental reading program that emphasizes phoneme awareness and phonics with small groups composed of both at-risk native English-speakers and at-risk English language learners (ELLs) whose first language is not Spanish. A multiple-baseline-across-participants design was utilized to investigate the effects of the intervention. Findings indicate that individual students placed in small reading groups comprised of ELLs and native English-speakers benefited from the code-oriented intervention, reinforcing the use of evidence-based instruction and more inclusive grouping practices for instruction. When disaggregated by language status, both ELLs and native English-speakers benefited from the supplemental reading instruction. Educational implications and areas for future research are discussed.
