What is declared by the presiding officer to signify that the meeting has begun?

The term used to signify that a meeting has begun is "call to order." This is a formal declaration made by the presiding officer, indicating that the meeting is officially starting and that attendees should focus their attention on the proceedings. It establishes order and allows the group to move forward with the agenda.

A call to order is essential because it marks the transition from a casual gathering to a structured meeting where parliamentary procedures will be followed. This action also sets the tone for the meeting, signaling that discussions and decisions will take place within an organized framework.

Other terms like "opening statement," "meeting initiation," and "session start" do not carry the same formal significance and are not recognized as the official term used in parliamentary procedure. The precise language of "call to order" is widely understood within the context of meetings and facilitates clarity among all participants regarding the status and expectations of the gathering.
