What Amish period of exploration commonly begins around age 16?

The Amish period of exploration that commonly begins around age 16 is called Rumspringa.

Rumspringa is a period in which Amish adolescents experience a degree of freedom before deciding whether to be baptized into the Amish church. The Pennsylvania German term is commonly translated as “running around,” although practices differ greatly among Amish communities.

Popular culture often portrays Rumspringa as a single, dramatic period of rebellion. In reality, some young people continue living much as they did before, while others spend more time outside Amish social boundaries. The length and activities of the period are not identical everywhere.

The important decision comes later: baptism is a voluntary commitment to the church and its Ordnung, the community’s rules and practices. Those who are baptized and later leave may face social consequences, depending on the church district. Rumspringa therefore concerns choice and community membership, not simply a fixed teenage festival.
