Assess Needs & Resources

One of the first steps in local health improvement is to take stock of your community's needs, resources, strengths, and assets. You will want to understand what helps as well as what deters progress toward improving your community’s health.


Understand current community strengths, resources, needs, and gaps to help you decide where to focus your efforts.

Who to Involve

Look to the groups in the center of the Take Action Cycle. How will you harness the collective power of leaders, partners, and community members, including those who are experiencing the worst conditions for good health?
