Abiriba has a well-developed and active Age-Grade system, one of the most effective ones in Igbo land. Some Age-Grades include: Akahaba, Erinma I & II, Ekpankuma I & II, Onyiba, Egwuena, Ojighiri, Isimini, Okezie etc., Amogudu people start age grade and are the founders of age-grade, they as well give the age grade's name & they have the right to change the name based on the achievement of the age grade. These age grades maintain offices in all countries of the world where Abiriba people reside. The Age Grades have been the main agents of development in the town, especially those in the diaspora. They also play the traditional role of policing the community and punishing offenders, regardless of age and status.
