An important way to address the literacy needs of English learners (ELs) is to ensure that ELs receive evidence-based literacy instruction and intervention. To support teachers’ implementation of this instruction and intervention, it is necessary to provide effective professional development (PD). In this systematic review, we synthesized 19 studies that investigated PD on literacy instruction and intervention for ELs. Findings revealed that although PD often targets teachers’ implementation of literacy instruction, PD is less likely to focus on teachers’ implementation of literacy interventions for ELs experiencing reading difficulties. Nonetheless, PD programs typically resulted in positive changes in teachers’ knowledge and practices. However, only 12 of the studies reported on student outcomes. We conclude with research and practical implications related to PD for teachers of ELs that is responsive to the needs of ELs.
