Organizations and activists can inform and shape decisions around policy, budget and draft legislation by engaging with government officials and lawmakers at all levels. By providing decision makers with expert knowledge of their area of practice, organizations and activists can provide critical information that would not otherwise be brought to the government’s attention about how certain policies, procedures and laws operate on the ground and affect the communities they represent. This guide is designed to support disabled persons organizations and disability rights advocates to develop a plan for strategically engaging decision makers at the local, regional and national levels. The guide provides an overview of the various components that make up a decision maker engagement plan and considerations for successful engagement.
