The objectives of this review are to answer the following research questions: (1) What is the nature of the interventions used to support education for people with disabilities? (2) What is the size and quality of the evidence base of the effectiveness of interventions to improve educational outcomes for people with disabilities in low- and middle-income countries (LMICs)? (3) What works to improve educational outcomes for people with disabilities in LMICs? (4) Which interventions appear most effective for different types of disability? (5) What are the barriers and facilitators to improving of educational outcomes for people with disabilities? Is there evidence of cumulative effects—that certain interventions are effective when done in combination with others, but are less or ineffective when done alone?
