What grade is my kid in Wyoming?
Wyoming moved its cutoff from September 15 to August 1 under H.B. 0174. September 15 now matters only as the outer limit for an early-admission request.
Recently changed. This cutoff took effect for the 2023–24 school year. If you are going from an older chart or a sibling's experience, check the date again — Wyoming is not where it used to be.

How Wyoming compares
5 states use the same August 1 cutoff: Arkansas, Indiana, Kentucky, Missouri and Nevada. 4 have an earlier cutoff and 35 have a later one, so a child born the same day can land a full grade apart depending on where they live.
10 states require school attendance to begin at age 7, Wyoming among them. 39 states and DC start compulsory schooling earlier.
Like most of the country, Wyoming does not mandate kindergarten — only 17 states and DC do.
Starting early in Wyoming
For a child born on or before September 15, a parent may request early admission based on a kindergarten-readiness assessment.
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.
