Wisconsin Four-Year-Old Kindergarten


  • Public Pre-K


In 1898, the Wisconsin State Legislature voted to permit schools to establish 4-year-old kindergarten (4K) alongside 5-year-old kindergarten (5K). 4K is now available to all children who turn 4 years old on or before September 1st of the school year. The program is universalUniversal Pre-K: programs in which the sole eligibility criterion is age., free, and voluntary for families, and it is offered through a mixed-delivery system. 4K’s delivery model is varied and includes half-day and full-day programs, offered across 97% of the state’s districts and in partner child care, Head Start, and private programs. Wisconsin received a Preschool Development Grant Birth to Five Renewal in 2021, which was used to conduct a needs assessment and development of a strategic plan to further expand access to public programs.

Connections to Key Early Learning Study at Harvard (ELS@H) Findings:

High-quality, affordable early education and care supports children’s healthy development and allows families to work, engage in their own educational pursuits, and/or participate in other aspects of community life. To support children and families in these instrumental ways, research suggests there is a need to expand the availability of early education opportunities across the mixed-delivery system.

Findings from the Early Learning Study at Harvard (ELS@H) show:

  • Families rely on a range of formal (e.g., Head Start, center-based care, public pre-K) and more informal (e.g., home-based, relative care) early education settings; when choosing a setting for their child, families balance many logistical constraints and personal preferences.
  • But for many families – and especially low- and middle-income families – early education choices remain tightly constrained due to issues of affordability and supply.
