This chapter synthesizes the outcomes of 17 meta-analyses and systematic reviews conducted between 2011 and 2024, that summarize the effects of family literacy programs (FLP’s) on children’s literacy skills. The synthesis shows that, across different intervention approaches and target groups, FLP’s yield positive effects, both on child and parent outcomes. Additionally, several trends and biases were identified. There is a strong focus on shared reading interventions and on programs targeting the age range 0 to 6 as well as a strong geographical bias: Most studies were conducted in Anglo-Saxon countries. Programs with a targeted approach appeared to have stronger effects and there has been increased attention for programs adapting activities to diverse target groups. Some literature reviews have targeted specific subpopulations—children from low-SES families, dual language learners, and children with special educational needs—, generally showing positive results. An important drawback is that only a few studies have assessed the long-term effects of FLP’s.
