The Universal House of Justice has announced consecutive multi-year plans. From 1996 to 2000, the Four Year Plan focused on strengthening "communities, institutions, and believers." From 2000 to 2001, the Twelve Month Plan focused on creating activities and further building an administrative structure. In this time the Regional Baháʼí Council (RBC) was created in very large countries, where an intermediary was necessary between the National and Local to help National Assemblies communicate and interact with local communities. From 2001 to 2006, the Five Year Plan has focused on three so-called core activities, which comprise devotional gatherings, children's classes, and study circles. An additional aspect newly created was the categorizing of areas into "clusters" that comprise groupings of communities, such as a metropolitan area or county. From 2006 to 2011 the Five Year Plan introduced Junior Youth Activities recognizing the pre-adolescent years as crucial in a person's spiritual growth.
