Local chambers have ample experience boosting development in their communities.
They are also able to muster grass roots support for a national agenda that benefits all businesses. In turn, the local chambers' standing in their own communities is strengthened by their connection to the national chamber and adherence to sound membership service standards. The US Chamber of Commerce has promoted such standards in its accreditation program. It also gives a local area's business community proof positive that the organization is doing a good job of representing its interests. Accreditation is a method for a national chamber to promote quality among local chambers.
