The Growing Up Great! VYA Toolkit is an age-appropriate, gender transformative intervention package that provides both in-school and out-of-school very young adolescent (VYA) girls and boys aged 10-14 years with accurate information about sexual and reproductive health (SRH), and fosters discussion about related social norms. The VYA Toolkit was adapted from materials used in the Gender Roles, Equality and Transformation (GREAT) Project and incorporates elements of other evidence-based programs for this age group, including Choices, Voices, Promises and GrowUp Smart, a puberty education curriculum for VYAs. Additional support materials for parents, teachers and health providers are included throughout the Growing up Great Implementation Guide.
