Participatory Needs Assessments You’re going to start working immediately with a community by facilitating a participatory needs assessment. The assessment will be done in a community workshop that will take approximately four hours. In this workshop you will work with the community to explore their thoughts on their needs, wants, problems, and challenges. You’re going to provide attendees with communication tools designed to illuminate and capture their knowledge about their community and about their needs. Given the right tools, most communities are fully capable of assessing their needs and designing adaptive programming.
