Mayville School District

A z-score places the district's Forward result against every Wisconsin district that year: 0 is the average district, +1 one standard deviation above. Because each year stands on its own, z-scores compare across the 2023-24 rescaling, when percentages cannot. In 2024-25, Mayville scored −0.85 in ELA and +0.14 in math (17th and 52nd percentile statewide); over the last three tested years it averaged −0.19 and +0.42.

Expected z-score given demographics

The Expected section’s two benchmarks on the z scale: the model fitted to every other Wisconsin district, and the peers’ own z-scores moved to the district’s demographics, size and property wealth, then their median. Filled dot: gap from the Wisconsin expectation; ring: gap from the peer expectation.

Compare groups on the z scale

Each student group's result against the same group in every other Wisconsin district (0 = the average district's result for that group), with the Wisconsin model's expectation for the district's students in that group.

Proficiency rates (the share meeting or exceeding) follow in the Achievement section. 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.

Mayville enrolled 922 students in 2025-26 (the September headcount certified by DPI). Since 2014-15 its enrollment has fallen 23%; the median regional peer shrank 17% and the median Wisconsin district shrank 9%. The chart indexes each series to its 2014-15 level. Private schools inside the district's boundaries enroll 17.7% of school-age children (2024-25), against 9.7% in the median district.

Children who live here and students who attend

Two DPI counts describe Mayville's size. In 2024-25, 1,082 children lived in the district by DPI's September membership count (full-time equivalent, so four-year-old kindergarten counts part-time; the revenue limit averages it over three years), and 944 students attended its schools. Open enrollment connects them: 125 residents attended other districts and 103 students from other districts came in. Since 2014-15, the resident count has fallen 7% while attendance has fallen 21%, as net transfers out went from 34 to 22.

Residents: children living in the district, by DPI September membership (full-time equivalent), the count the revenue limit is built from. Open enr. out / in: students open-enrolled to other districts and from them. Attending: DPI certified enrollment (September headcount). Open enrollment: DPI open enrollment annual reports, transfers rather than applications. Residents minus transfers out plus transfers in comes close to attendance; the remaining gap is mostly four-year-old kindergarten, which membership counts part-time. A dash means DPI has not yet published that count.

The entering class

Mayville enrolled 46 kindergartners on average over the last three years, −27% against the three years ending 2016-17, where the median regional peer moved −14% and the median Wisconsin district −12%. Over the same span its K–12 count moved −19% and the median regional peer −13%.

Where a falling enrollment line comes from matters more than its slope. Following each class from one grade to the next, Mayville gains students as its cohorts move up — 1.026 per student at 10 of 12 grade steps, against 1.009 for its regional peers. Children already enrolled here are not leaving as they get older; the decline arrives at the front door, in the size of each entering class.

DPI certified enrollment by grade level, the third-Friday-of-September count. Kindergarten is five-year-old kindergarten; four-year-old kindergarten is a separate program and is excluded. Three-year averages at each end, because a single district's kindergarten is a few hundred children and one year swings several percent on noise. Progression is students in grade g+1 the next year per student in grade g, averaged over 2014-2025; above 1.00 the cohort gained students. Regional figures cover the 12 regional peers with grade-level data.

Home values against nearby districts

On the 2025 tax roll the median home in Mayville was worth $241,600, 14% below the median of the 21 districts within 25 miles ($281,150). That ranks 16th of 22 in the area and at the 44th percentile of Wisconsin districts (state median $263,500).

Wisconsin Statewide Parcel Map (State Cartographer's Office), 2025 tax roll: the median estimated fair market value (assessed value over the municipality's assessment ratio) of parcels classed residential only with a building on them, so vacant lots, apartment buildings of four or more units and homes on parcels that also carry farm, forest or undeveloped land are left out. Unlike the Census figure, the roll includes seasonal homes. Nearby districts are those whose NCES office address lies within 25 miles of Mayville's: Erin (19 mi, $542,400); Holy Hill Area (25 mi, $498,750); Slinger (17 mi, $453,000); Hartford UHS (15 mi, $387,000); Kewaskum (16 mi, $373,550); Hartford J1 (15 mi, $348,600); West Bend (19 mi, $337,600); Herman-Neosho-Rubicon (13 mi, $333,400); Hustisford (11 mi, $313,800); Campbellsport (15 mi, $283,350); Oakfield (13 mi, $281,150); Watertown Unified (23 mi, $275,600); Lomira (9 mi, $262,700); Rosendale-Brandon (23 mi, $258,950); Beaver Dam Unified (14 mi, $245,900); Fond du Lac (20 mi, $234,500); Waupun (13 mi, $228,900); Horicon (5 mi, $225,400); Randolph (23 mi, $219,600); North Fond du Lac (23 mi, $217,450); Dodgeland (10 mi, $206,500).

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. Mayville's revenue-limit membership for 2025-26 is 947.

DPI revenue limit worksheets (three-year average membership) and DPI September membership. Years without a membership count show a dash.

In spring 2025, 42% of Mayville students met or exceeded Forward standards in ELA and 58% in math, against 54% and 57% in the median Wisconsin district.

Z-scores, their trend and the expected values open this report (Achievement on the z scale); this section reports proficiency rates and the other outcomes.

Attendance, ACT and discipline

DPI WISEdash files. Chronic absenteeism = share of students missing 10% or more of enrolled days.

Mayville's day-to-day cost per member was $14,107 in 2024-25, against $14,150 for the median peer and $14,960 for the median Wisconsin district. This is DPI's current educational cost: instruction and instructional support, without construction, debt service, transportation or food service, which rise and fall with building projects rather than with what a year of school costs. Counting all of those, DPI's total district cost per member was $17,645, against $17,466 for the median peer and $18,324 statewide. Local property tax paid for 38% of revenue, against 38% statewide.

The revenue limit allows $13,465 per member for 2025-26, below the statewide K-12 median of $13,575 and above the peer median of $12,678. The limit counts general state aid and the property tax together, so state aid changes move the levy rather than total revenue. It has never asked voters to exceed the limit.

Total district cost per member and revenue shares: DPI comparative cost data. Revenue limit: DPI revenue limit worksheets; statewide comparison is K-12 districts only.

The district's 2025-26 levy is $7.6M, at a rate of 6.97 mills per $1,000 of equalized value (statewide K-12 median 6.90). 37% of the levy repays referendum-approved debt (Fund 39).

The median residential property-tax bill inside the district, all governments, was $2,893 in 2025 (statewide median $2,766). The median home on the 2025 tax roll is worth $241,600; the school portion of its bill is about $1,680.

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

A home at Mayville's median value, about $242,000 at the current assessment, owes roughly $3,120 in property tax for taxes payable 2026. The school district's part is $1,680 (49% 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 $320 less than the bill on the median regional peer's median home.

Each column is the tax on that district's own median home. Peer columns show the median across the group's districts, figure by figure, so their rows need not add to the total. The percentage is each authority's share of the bill before credits.

The same $242,000 home at each group's tax rates

Holding the house constant separates tax rates from home values. Taxed at Mayville's rates the home owes $3,120; at the median regional peer's rates it would owe $3,390.

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: the median of the 2,463 residential parcels with a home on them on the 2025 tax roll (January 1, 2025), at the estimated fair market value the roll reports (assessed value over the municipality's assessment ratio); parcels that also carry farm, forest or undeveloped land are left out.

The parcel-based median bill above runs lower because it covers every residential parcel, including vacant lots, and is net of the per-parcel credits.

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 tax rate to the tax-roll median home value and is an estimate.

Voters have decided 5 referendum questions since 1995 and approved 2. All were capital questions; the district has never asked voters to exceed the limit.

3 of the 12 peers have a question before voters on November 3, 2026: Oconto Unified (non-recurring $4.5M); Westfield (non-recurring $7.0M); Whitehall (non-recurring $2.5M). Mayville also has a question on that ballot. At the most recent election, April 2026, 3 questions among Mayville and its peers went to voters and 1 passed.

Since 2016 the peers have passed 20 of 26 (77%) of their questions: 7 of 13 (54%) of revenue-limit (operating) questions and 13 of 13 (100%) of debt questions. Mayville's record over the same years is 1 of 1 (100%). In 2026-27, 4 of these 13 districts have voter approval to exceed the revenue limit.

Wherever this briefing sets Mayville beside other districts, it uses the groups below. A group figure is the middle value across its members, each counted equally, so one large member cannot dominate it.

Peers 12 districts

The 12 Wisconsin districts of the same type most like Mayville on four equally weighted factors: total enrollment (compared as a ratio, so half as large counts as near as twice as large), day-to-day cost per member, students per staff member (full-time equivalent) and the share of economically disadvantaged students, each difference scaled by how much the factor varies across districts, and none more than two standard deviations away on any one. The group starts with nearby districts that match closely (within half a standard deviation on average) and fills the rest from anywhere in the state. Mayville: 922 students, $14,107 day-to-day cost, 6.6 students per staff member, 44.1% economically disadvantaged. Peers carry the achievement, spending and staffing comparisons.

Regional peers 12 districts

The 12 districts of the same type within 25 miles of Mayville, straight line between district offices, whose profile on the same four factors is comparable: on average within one standard deviation of Mayville’s. They carry enrollment, property taxes and home sales, and their median sits beneath the peer median elsewhere. Districts in both groups appear in both lists.

“Wisconsin median” is the middle value across Wisconsin districts; property-tax and revenue-limit comparisons use K-12 districts only, because elementary and union high school districts overlap the same territory.
