Wisconsin 4-year-old kindergarten, almost always referred to as 4K, is the state's nearly universal public preschool program. More than 95 percent of Wisconsin school districts offer 4K, and the program is free to families. What makes Wisconsin distinctive is the Community Approaches model: rather than serving children only in public school buildings, most districts deliver 4K through partnerships with licensed child care centers, Head Start sites, and family child care homes, so a four-year-old can stay at her existing daycare and have the daycare deliver the 4K curriculum during the school day.
This guide walks through eligibility, the three district delivery models, how 4K interacts with private daycare via Community Approaches, the wrap-around math, and how to enroll for the 2026 to 2027 school year.
Wisconsin 4K is funded through the state's regular school aid formula, the same mechanism that funds K-12 education. Districts that operate 4K receive per-pupil state aid, with additional categorical aid available for districts that use the Community Approaches model. The result is that nearly every Wisconsin school district offers a free 4K program, and roughly 70 percent of those districts deliver some or all 4K seats through community partners.
Each 4K seat must provide a minimum of 437 hours of instruction across the school year (roughly half-day, five days per week). Many districts run a longer school-day program; others run a half-day model with a full-day partner option.
Wisconsin 4K is universal in availability, not income-tested:
There is no income test, no language test, and no immigration-status test. The only meaningful constraint is whether the family's home district offers 4K. As of the 2025 to 2026 school year, more than 95 percent of districts do.
| Model | Where it happens | Hours |
|---|---|---|
| School-based only | Public school elementary classrooms | Typically half-day (2.5 hours) or full-school-day |
| Community Approaches | Licensed child care centers, Head Start sites, family child care homes that partner with the district | Half-day instructional plus wrap-around at the same site |
| Hybrid | Mix of school-based and community partners | Varies by site |
Roughly 70 percent of districts use Community Approaches in some form. Milwaukee Public Schools, Madison Metropolitan, and Green Bay Area all operate substantial community partner networks. Smaller and rural districts often use school-based delivery.
In Community Approaches districts, four-year-olds can stay at their existing daycare while receiving the 4K curriculum during designated instructional hours. The mechanics:
Family income: $78,000 (no eligibility test for 4K, so income is not a factor).
Before 4K enrollment: full-day preschool at a Milwaukee YoungStar 4-star center at $1,025 to $1,275 per month (Milwaukee preschool rate per US DOL National Database of Childcare Prices Wisconsin data).
After enrollment in Milwaukee Public Schools Community Approaches 4K at the same daycare: state aid covers the 2.5-hour 4K block (typically valued around $300 to $375 per month). Family pays the daycare for remaining hours and any summer programming.
New cost: $700 to $950 per month blended across the calendar year, or $8,400 to $11,400/year.
Annual savings: $3,000 to $4,500.
Every Wisconsin 4K classroom (school-based or community) must align to the Wisconsin Model Early Learning Standards and use a DPI-approved curriculum. Lead teachers in a 4K classroom must hold (or be working toward) Wisconsin Department of Public Instruction licensure with an early childhood endorsement. Class size is capped at 17 to 20 depending on district policy, with a 1:8 to 1:10 staff-to-child ratio.
Does Wisconsin offer 3K? A small number of districts (including Milwaukee Public Schools and some metro Milwaukee suburban districts) offer 3-year-old kindergarten (3K), funded through a similar mechanism. Statewide 3K availability remains limited.
What is YoungStar? YoungStar is Wisconsin's Quality Rating and Improvement System (QRIS). It rates licensed providers on a 2- to 5-star scale. Families targeting Community Approaches 4K typically look for 3-, 4-, or 5-star sites.
Can my child attend 4K and a separate daycare? Yes. Many families pair a half-day school-based 4K classroom with a full-day daycare or in-home provider for the remaining hours.
