28 states require school attendance to begin at age 6, Oregon among them. 11 states and DC start compulsory schooling earlier.
Like most of the country, Oregon does not mandate kindergarten — only 17 states and DC do.
Starting early in Oregon
A school board may admit a child below the minimum age when it best serves the child’s cognitive, social and physical needs.
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.
