11 states and DC require school attendance to begin at age 5, South Dakota among them. That is as early as anywhere in the country requires it.

South Dakota is one of 17 states and DC that require kindergarten attendance outright; in most of the country it is optional.

Starting early in South Dakota

A child transferring from another state may continue their program without interruption.

Early entrance is decided locally even where state law allows it, so ask your district office what evidence they expect and when the window closes.
