Policymakers, program managers, and service providers—teachers, health care providers, extension agents, religious and community leaders—need the competencies (knowledge, skills, and attitudes) to serve and support adolescent boys and girls in accordance with global recommendations and national policies and protocols. This will require clear job descriptions, training (pre-service or in-service, offsite or on-the-job), mentorship, and supportive supervision, along with access to effective strategies, tools, and resources. Adolescents and their families also need competencies to support, adopt, and sustain healthy dietary practices. The Adolescent Nutrition Resource Bank currently includes capacity-building materials, primarily for service providers. If you have guidance or materials for building the capacity of policymakers, program managers, service providers, families, and adolescents about adolescent nutrition,, please send them to email@example.com.
