Enrollment and the funding count

Wisconsin's revenue limit, which caps what a district may raise from general state aid and the property tax combined, is set per member using a three-year rolling average of membership: each September's full-time-equivalent count plus 40% of summer-school FTE. Twin Lakes #4's revenue-limit membership for 2025-26 is 346.

In spring 2025, 43% of Twin Lakes #4 students met or exceeded Forward standards in ELA and 58% in math, against 54% and 57% in the median Wisconsin district.

On a z scale, which puts every year on the same footing across the 2023-24 rescaling, Twin Lakes #4 averaged −0.66 in ELA and −0.27 in math over the last three tested years, against −0.80 and −1.24 in its first three years on file.

Wisconsin rescaled the Forward Exam in 2023-24. Z-scores standardize each year's result against every comparable district that year (0 = the average district; +1 = one standard deviation above), so years on either side of a test or cut-score change can be compared. Testing was canceled in spring 2020.

Property tax on the median home, by taxing authority, payable 2026

A home at Twin Lakes #4's median value, about $322,000 at the current assessment, owes roughly $3,230 in property tax for taxes payable 2026. The school district's part is $1,480 (39% before credits); the rest goes to the county, the city, village or town, the technical college district and special districts such as sanitary and lake districts, less the state's school levy tax credit. That bill is $2,040 less than the average regional peer's median home.

Wisconsin Department of Revenue, Town, Village and City Taxes, 2025 levies (taxes payable 2026): each taxing body's levy over the full value it is spread on. The school rate is the district's own levy over its equalized value; county, municipal, technical college and special-district rates are averages over the towns, villages and cities the district covers, weighted by its value in each, so a home in any one of them pays somewhat more or less. The school levy tax credit is the state-paid credit DOR spreads by municipality; the lottery and gaming credit and first dollar credit, applied per parcel, are not included. Median home value: Census ACS 2024 5-year median for owner-occupied homes, brought to January 1, 2025 values by the change in the district's TIF-out equalized value since 2022. The parcel-based median bill above runs lower because it covers every residential parcel, including vacant lots, condominiums and smaller homes, and is net of the per-parcel credits. For an elementary or union high school district the school row is this district's levy only; homes here also pay the paired district's school tax.

Levy by fund and equalized value: DPI and Department of Revenue. Typical bill: parcel-level residential bills inside the district boundary; school portion applies the school mill rate to the ACS median home value and is an estimate.
