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.

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.
