The Helmut-Schmidt Programme includes courses around public policy, development, governance, social protection, peace and conflict, nonprofit management and related fields. These themes overlap, but they are not identical. A public policy course may focus more on policy design and analysis. A development governance course may focus on institutions and development processes. A social protection course may focus on welfare systems, labour, poverty and social-policy instruments.
Read module descriptions, not only course titles. A title can sound perfect while the curriculum is more quantitative, more administrative, more research-focused or more sector-specific than expected. If you dislike the actual modules, the course may not be the right fit.
Your motivation letter should reflect the course theme. If you apply to a peace and conflict course, your examples should connect to conflict prevention, peacebuilding, security, governance or social cohesion. If you apply to social protection, your examples should connect to poverty, labour, welfare, social policy, inclusion or public-service delivery.
