PurposeAfter comprehensive review of discourse surrounding school-banking programmes and marketing to children, the authors develop evidence-based guidelines for such programmes. Guidance for organisations is provided to ensure they understand these products' impact on children and other vulnerable consumers.Design/methodology/approachA comprehensive, systematised review of literature related to school-banking programmes was undertaken during 2019, 22 Boolean searches were collated, appraised using a five-step quality appraisal framework and analysed against selection criteria. To accommodate literature across disciplines, quality appraisal combined two existing hierarchies of evidence and peer-review status.FindingsSearches returned over 375,000 articles; 149 were relevant and met quality thresholds. Evidence supports the role of financial education in producing positive financial outcomes. However, education should involve communities and families to enhance consumer socialisation and limit negative consequences. From this, guidelines are presented accounting for students' and parents' ability to understand marketing messages and the impact of in-school marketing on students – including on longer-term perceptions, attitudes and behaviours.Practical implicationsGuidelines are to assist financial institutions, policymakers and schools balance the benefits of financial literacy and education with potentially negative consequences of school-banking programmes. Classifying programmes as marketing rather than CSR also benefits organisations contributing corporate resources and voluntarily engaging practices underpinned by commitment to community well-being.Originality/valueAvoiding moral panic, the authors instead outline evidence-based guidelines on school-banking programmes. The quality appraisal process used in this review offers a new approach to synthesising inter-disciplinary evidence.
