The central committee is designated as the highest organ of a communist party between congresses. Per the principles of democratic centralism and unified power, the central committee is empowered to deal with any issue that falls under the party's purview. While formally retaining this role in socialist states, commonly referred to as communist states by outside observers, in practice, it delegates this authority to numerous smaller internal organs due to the infrequency of its meetings. The term of a central committee of a ruling communist party is usually five years. The party congress elects individuals to the central committee and holds it accountable. At the first central committee session held immediately after a congress, it elects the party leader, an office usually titled general secretary of the central committee, a political organ, commonly known as the politburo, and a executive organ, customarily named the secretariat.

The terms party conference, political convention, and party congress usually refer to a general meeting of a political party. The conference is attended by certain delegates who represent the party membership. In most political parties, the party conference is the highest decision-making body of the organization, tasked with electing or nominating the party's leaders or leadership bodies, deciding party policy, and setting the party's platform and agendas.
