The scoping project documented in this report presents the results of a rapid, comprehensive and systematic review of empirical evidence from the past 10 years, conducted with the following aims:

• to evaluate the effectiveness of interventions to promote gender equity and prevent gender bias among children aged 3–5 years
• to synthesise empirical studies regarding the development of gender roles, bias and stereotypes among children aged 3–5 years.

This project emphasises a primary prevention approach – that is, it focuses on population-level approaches rather than individual, treatment-focused action.
