Impact of Service-Learning Among Adolescents: A Systematic Review

Service-learning has emerged as a promising pedagogical approach to address social challenges while fostering students’ academic, socioemotional, and civic development. Despite the growing body of literature, there is a lack of systematic reviews evaluating its effectiveness in secondary education beyond the United States. Therefore, this systematic review aimed to synthesize the available empirical research on service-learning interventions implemented with secondary education students (grades 7–10) outside United States. Following The Campbell Collaboration guidelines, a comprehensive search was conducted across Web of Science and ProQuest, supplemented by other resources (general web search, hand searches, ongoing research, open access and relevant institutions and networks). Inclusion criteria required quantitative empirical studies (randomized controlled trials, quasi-experimental designs, or pretest–posttest designs) published from 2008 to June 2025 that measured academic, cognitive, socio-emotional, civic, and community outcomes using quantitative procedures. After screening, 10 studies met the inclusion criteria. The findings indicate that service-learning programs can generate positive outcomes on academic performance and non-cognitive skills. Nevertheless, methodological weaknesses and heterogeneity across studies prevent drawing robust conclusions. The review highlights the need for more rigorous research to strengthen the evidence base for service-learning among adolescents in systems worldwide.
