The General Assembly normally meets annually, during the first full week in June.
At the level of the island of Ireland, the General Assembly stands at the top of this structure.
Women's and youth organisations, deaconesses and sister churches are also entitled to send delegates, giving a total membership of around 1,300.
The sitting Assembly first installs a new Moderator of the Presbyterian Church in Ireland, who acts as a presiding officer for the rest of the session.
After the Assembly rises at the end of the week, the Moderator spends much of the rest of the year as its ambassador.
