This idea of pre-k as an educational entry point is proven over and over again by creating highly academic Kindergarten standards. As kindergarten moves away from early childhood developmental approaches there becomes a new and necessary entry point. An entry point with play at the center and discovery a necessary.

Opportunities for Using Pre-K to Strengthen and Advance State Education Reform Efforts
On a broad policy level, Councils can provide a forum for informing state public education leaders about the array of early learning programs that can undergird reform efforts.
Connections between early learning and public education can vary from one community to another, and Councils can help communities find the linkages that work best for them.
POLICY REFORM IS KEY:
The ability to position pre-k as a starting point for public education depends on the maturity and effectiveness of a state’s program. States with a well established and successful pre-k should think about how changes in education policy connect to early learning, with pre-k serving not only as an important element of reform but also as a key connection point between kindergarten and programs serving younger children. States with less mature programs may want to focus on how expanding and evaluating the long-term impact of pre-k could support reform efforts.
