Nonprofit Board Members act as trustees of an organization's assets and provide oversight, foresight and insight. They are often compared with crows perched on the crows nest, scanning for storm clouds and rainbows. While they're not in charge of the daily tasks, they should be able to see the big picture and know what is needed to make things happen.
There are a variety of resources to help you find the right board members, whether your nonprofit is established or just beginning its journey. One of the most effective is to connect with your existing volunteer base. Check out your current committees, events and youth leadership groups for individuals who seem to have the potential to become great leaders. You can also utilize your newsletters and social media to advertise your board opportunities to your neighborhood.
Another option is to look on job boards for non-profits or mission-driven organizations, such as Impact Opportunity and Idealist. Also, search within your professional fields to find people who might be connected to nonprofits through their industry associations or businesses that give to them as part of their charitable giving. Reach out to those who seem like an ideal candidate and ask whether they're interested in being on your board.
As with any staff member, newly appointed board members must receive an extensive orientation to ensure they understand their responsibilities as well as commitment. This includes a set of clear expectations regarding meeting attendance and agendas, fundraising, the roles for which board members are recruited (e.g. budget management) as well as other policies regarding governance.
