What characterizes a three-tiered organization?

A three-tiered organization is characterized by a hierarchical structure where local associations unite under state associations, which in turn are affiliated with a national association. This model creates a network of organizations at three distinct levels, facilitating communication and resource sharing among them. Local associations benefit from support and advocacy provided by the state level, while state associations represent the collective interests of the local groups at the national level.

The other options do not accurately reflect the nature of a three-tiered organization. A single level of membership suggests a flat structure without the layers that define a three-tier system. An arrangement between several organizations could imply a loose coalition, which is different from the structured hierarchy of local, state, and national associations. Lastly, stating that national associations operate independently of state levels contradicts the interconnectedness and mutual support that are hallmarks of a three-tier system, where each level relies on and collaborates with the others to strengthen the overall organization.
