Coming of Age (CoA, COA) is a Unitarian Universalist program in which a congregation fosters the transition of its children into youth. Although COA programs vary by congregation, they typically mark the individual's transition from younger religious education programs into a youth group, District-level/Regional Young Religious Unitarian Universalists (YRUU), as well as National and Continental-level YRUU. Not all youth will enter into all of the levels of programming above, though entering into at least congregational-level YRUU (Youth group) is very common. At least one of the UUA districts holds a series of COA retreats to supplement congregational COA programs.
