The General Administration Department (GAD) is the nodal department for overall policy formulation in Meghalaya. It is responsible for the formulation, implementation, and monitoring of all government policies and programs. The GAD also provides administrative support to all other departments of the government.
The Home Department is responsible for law and order, police, prisons, and disaster management. The Forest Department is responsible for the management of forests and wildlife. The Sports Department is responsible for the promotion of sports and games in the state.
