COVID Gave Wisconsin Charters a 7,500-Student Boost They Never Gave Back

Fri, 10 Apr 2026 12:00:00 GMT

In a single school year, Wisconsin's charter sector gained more ground than it had in the previous five years combined. Between 2019 and 2021, charter schools added 7,570 students -- a 17.5% increase -- while traditional public schools lost 36,468. Charter share jumped a full percentage point, from 5.0% to 6.1%, and has held at 6.0% every year since.

Nearly 90% of that surge came from virtual schools, which doubled enrollment during the pandemic. Four years later, the traditional sector has not recovered those students. The charter sector has not given them back.

A sector that plateaued, then surged

Wisconsin's charter sector grew rapidly from 2006 to 2014, climbing from 27,553 students (3.2% of public enrollment) to 45,069 (5.2%). Then growth stalled. From 2014 to 2019, charter enrollment actually declined slightly, falling to 43,291, as new school openings slowed and several Milwaukee-based charters contracted.

COVID changed that. In 2020-21, charter enrollment jumped to 50,861, the sector's all-time high. The gain of 6,158 students in a single year was the largest in the dataset, eclipsing even the 5,821-student jump in 2008 when Wisconsin was still scaling up its charter authorization framework.

Since 2021, charter enrollment has settled around 48,500 to 49,700. The sector has given back about 2,400 students from its pandemic peak but remains 5,182 students above its pre-COVID level, a 12.0% net gain over six years. Traditional schools, by contrast, fell from 815,542 to 757,408 over the same period, a loss of 58,134 students (7.1%).

Virtual schools drove the entire surge

The mechanism is not subtle. Virtual charter enrollment doubled from 6,502 students in 2019 to 13,263 in 2021, a gain of 6,761 students. Brick-and-mortar charter enrollment during the same period rose just 809 students, from 36,789 to 37,598. Virtual schools accounted for 89% of the total charter surge.

The largest beneficiaries were established virtual operators. Wisconsin Virtual Academy (WIVA), administered through the McFarland^↗ School District and operated by K12 Inc., gained 1,756 students across its K-8 and high school campuses. Wisconsin Connections Academy in Appleton^↗ gained 676. ARISE Virtual Academy in Janesville^↗ gained 633 students, growing from 101 to 734. iForward, based in Grantsburg^↗, added 391. Even smaller virtual operators saw enrollment triple or quadruple.

"The enrollment of Wisconsin's virtual charter schools nearly doubled to more than 16,000 students in the 2020-21 school year, according to state Department of Public Instruction figures." -- Capital Times, Dec. 2024

The pandemic rationale is straightforward: families who wanted an alternative to in-person instruction during COVID turned to existing virtual charters rather than navigating improvised remote learning from their home district. Virtual charters had the infrastructure, the curriculum platforms, and the enrollment capacity to absorb thousands of families in a single semester. Traditional districts offering emergency remote instruction were competing with schools built for online delivery.

The share plateau at 6%

Before COVID, charter share had been essentially flat for five years, hovering between 5.0% and 5.2%. The pandemic moved it to 6.1% in one year, and it has stayed between 5.9% and 6.0% since. This plateau suggests the sector has absorbed a new baseline of demand but is not continuing to gain ground. Post-COVID annual charter growth has turned slightly negative, at -1.2% per year from 2021 to 2025.

Virtual charters explain part of the stabilization. After doubling during COVID, virtual enrollment fell to 10,888 in 2022, then stabilized around 10,100 to 10,900 through 2025. Virtual schools still enroll 10,856 students, 67% above their pre-COVID level, but the initial surge has partially receded. Virtual charters now account for 22.4% of all charter enrollment, up from 15.0% before the pandemic.

Brick-and-mortar charters, meanwhile, have barely moved. They enrolled 36,789 students in 2019 and 37,617 in 2025, a gain of just 828 students (2.3%) over six years. The charter growth story in Wisconsin is almost exclusively a virtual school story.

The academic trade-off

The enrollment gains come with documented academic costs. Stanford researchers found that virtual charter students nationally received "58 fewer days of learning in reading and 124 fewer days in math per year" compared to peers in brick-and-mortar public schools, based on data from 2014 to 2019, before the pandemic further strained virtual models.

Wisconsin-specific results are similarly weak. In 2023-24, only about one-quarter of virtual charter students met state reading expectations and roughly one-fifth met math expectations. At WIVA's K-8 school, one in five students was proficient in English and one in ten in math. More than 40% of virtual charter students opted out of state testing entirely, further clouding the picture.

"But the data that we do have should give us a moment of pause." -- Kevin Lawrence Henry Jr., researcher, quoted in Capital Times

The tension is real: virtual charters serve families who actively chose them, often for reasons (medical needs, bullying, geographic isolation, scheduling flexibility) that traditional metrics do not capture. Low test scores may reflect the population these schools attract as much as the quality of instruction they deliver. But 10,856 students attending schools where fewer than one in four meets state reading benchmarks is a policy question Wisconsin has not resolved.

Where charters concentrate

Charter enrollment is not evenly distributed. Milwaukee^↗ accounts for 8,866 charter students, 18.3% of all charter enrollment statewide and 13.5% of Milwaukee's total district enrollment. The next-largest charter concentrations are in McFarland (3,584 charter students, 60.5% of district enrollment, almost entirely WIVA), Appleton (2,894, 19.3%), and Waukesha^↗ (1,586, 14.5%).

Several districts exist solely as charter operators. Milwaukee Science Education Consortium, United Community Center, Seeds of Health, Rocketship Education Wisconsin, The Lincoln Academy, and Milwaukee Scholars Charter School are all 100% charter entities authorized under Wisconsin's independent charter school statute, which allows non-district authorizers including UW-Milwaukee, the City of Milwaukee, and the Office of Educational Opportunity. Independent charter schools receive $12,369 per pupil in 2025-26.

Virtual charters create a particular distortion in district-level data. McFarland's enrollment of 5,921 appears to make it a mid-sized district, but only 2,337 of those students attend brick-and-mortar schools in the McFarland community. The remaining 3,584 attend WIVA from homes scattered across hundreds of districts statewide. Grantsburg^↗ (56.3% charter, driven by iForward) and Medford^↗ (37.2%, driven by Rural Virtual Academy) show the same pattern.

Two sectors pulling apart

Indexed to 2006, charter enrollment stands at 176 while traditional enrollment has fallen to 89. The sectors are moving in opposite directions, though at very different scales: charter's 20,920-student gain over 19 years is dwarfed by traditional's 89,003-student loss.

The divergence accelerated during COVID and has not reversed. From 2019 to 2025, charters gained 5,182 students while traditional schools lost 58,134. Even with the charter sector's post-2021 drift downward, the gap between the two trajectories continues to widen.

Combined with the state's four voucher programs, which enrolled more than 29,949 students in Milwaukee alone in 2025 plus additional participants in the statewide, Racine, and Special Needs Scholarship programs, Wisconsin's public school system is losing enrollment to choice alternatives at a steady pace. The Wisconsin Parental Choice Program's per-district enrollment cap has risen by one percentage point annually since 2017, and once it reaches 10%, no enrollment limit will apply, removing the last structural constraint on statewide voucher growth.

The 313 charter schools operating in 2025 are not going away. Neither is the 124-day math learning gap that Stanford researchers documented in virtual programs nationally. Wisconsin now has 10,856 students enrolled in virtual charters where fewer than one in four meets state reading benchmarks -- and more than 40% opt out of testing entirely. Those families chose these schools. The state has not yet decided what it owes them.

Wisconsin Lost 8,121 Students in a Single Year — and It Wasn't Even the Worst Recent Drop

Fri, 03 Apr 2026 12:00:00 GMT

The number that flashes brightest in Wisconsin's enrollment data is the one from the pandemic: 25,024 students gone in a single year, 2020-21. That was the crisis everyone saw. What the state is living through now is quieter but nearly as damaging.

Wisconsin lost 8,121 public school students in 2024-25, dropping total enrollment to 805,881. A year earlier, the loss was even steeper: 8,802, the largest non-COVID decline in the state's modern history. Together, the two most recent years erased 16,923 students from public school rosters, approaching the magnitude of the pandemic drop itself when spread across two years instead of one.

Of 441 districts reporting in both years, 282 lost students. Only 154 gained. Five were flat. The decline was not concentrated in one city or one region. It was everywhere.

The acceleration no one predicted

What makes the current moment alarming is not just the size of the losses but how sharply they diverge from the pre-pandemic trajectory.

From 2007 through 2014, Wisconsin averaged a modest loss of just 100 students per year. The state was essentially treading water. Then something shifted. From 2015 through 2019, average annual losses ballooned to 3,472. COVID pushed the single-year figure to 25,024 in 2021.

The expectation, in Wisconsin and nationally, was that enrollment would bounce back as pandemic disruptions faded. It hasn't. From 2022 through 2025, Wisconsin has averaged annual losses of 6,014 students, running 1.7 times faster than the pre-COVID decline rate. The post-COVID years are not a recovery. They are an acceleration.

Where the students disappeared

Milwaukee^↗ accounted for the single largest district loss in 2025, shedding 1,265 students to fall to 65,599. But the pain extended well beyond the state's largest district. Kenosha^↗ lost 404, Waukesha^↗ lost 396, and West Allis-West Milwaukee^↗ lost 323. Mid-size districts that once seemed insulated from decline were not: Appleton Area^↗ dropped 236, West Bend^↗ lost 226, and Eau Claire Area^↗ lost 179.

The few gainers tell their own story. McFarland^↗, which added 282 students, is home to the Wisconsin Virtual Academy, a statewide online charter whose students have never set foot in the district. Sun Prairie Area^↗, a Madison suburb, added 185 through genuine residential growth. Several charter operators round out the top gainers list: Milwaukee Science Education Consortium (+307), Rocketship Education Wisconsin (+102), and The Lincoln Academy (+101). The traditional districts that actually grew through families moving in can be counted on two hands.

Every grade shrank except 12th

The grade-level breakdown reveals where the pipeline pressure is building. Twelfth grade was the only level to post a meaningful gain in 2025, adding 2,092 students as a large cohort graduated out. That departure was not matched at the entry end: kindergarten lost 797, first grade lost 1,386, and prekindergarten lost 1,689.

Ninth grade recorded the single largest grade-level loss at 1,934, likely reflecting the transition from 8th grade's smaller incoming cohort. Tenth grade lost 1,332, and 11th grade lost 890. The high school levels that had been temporarily buoyed by larger pre-COVID cohorts moving through are now beginning to feel the contraction that elementary schools have absorbed for years.

The two-year compound

The combined 2024-2025 loss of 16,923 students is historically significant. For context, the COVID year erased 25,024 in a single blow. But the two most recent years, without any pandemic, without any single visible disruption, removed two-thirds of that amount through steady attrition.

Several factors are converging. Wisconsin's birth rate has fallen to 59,675 births in 2024, the lowest since before World War II. Each year's kindergarten class is smaller than the last. Meanwhile, the state's four voucher programs now serve more than 60,000 students, and open enrollment transfers move thousands more across district lines at $8,618 per student.

Revenue limits, frozen since 2009 when the legislature eliminated the CPI adjustment factor, have forced districts to rely on referenda to fund basic operations. Voters approved a record 148 school referendum questions in 2024, reflecting the extent to which the normal funding mechanism has broken down. Madison Metropolitan passed $607 million in combined referenda alone.

What the numbers portend

At the current pace, Wisconsin will drop below 800,000 public school students by 2026-27. The Wisconsin Policy Forum has concluded there is "no enrollment recovery in sight," attributing the decline to falling birth rates, migration to private schools and homeschooling, and lasting pandemic effects.

The 2025 cliff is not one event. It is two consecutive years of losses that dwarf anything the state experienced before 2020, delivered without the explanatory cushion of a global health emergency. Wisconsin's public school system is contracting at a pace that would have seemed implausible a decade ago, and the demographic pipeline offers no reason to expect a reversal.

Wisconsin Hits an All-Time Low: 805,881 Students

Fri, 13 Mar 2026 12:00:00 GMT

Every year since 2014-15, Wisconsin's public schools have opened with fewer students than the year before. The streak has now reached 10 observed years with no interruption, no plateau, no sign of a floor. In 2025-26, enrollment fell to 805,881, the lowest figure in the dataset and 69,661 students below the 2007 peak of 875,542.

The scale of the loss, 8.0% of peak enrollment, is roughly equivalent to emptying every public school seat in Milwaukee^↗, the state's largest district, and then emptying every seat in Racine^↗ on top of it. At the current pace of roughly 8,000 students per year, Wisconsin will drop below 800,000 by 2026-27.

The decline has two speeds

The trajectory breaks into distinct eras. From 2007 to 2014, enrollment was essentially flat: the state lost just 2,822 students across seven years, with gains in 2011, 2013, and 2014 nearly offsetting losses in the other years. The average annual change was negligible.

Starting in 2014-15, losses became consistent. Between 2015 and 2020, enrollment fell by 17,761, an average of about 3,550 per year, steady enough to feel manageable. COVID shattered that pace. The 2020-21 school year saw a single-year loss of 25,024 students, the largest annual decline on record. Wisconsin never recovered: enrollment has fallen by 49,078 since 2019-20, a 5.7% contraction in five years.

What changed after COVID is the rate of non-pandemic losses. Before the pandemic, Wisconsin was losing roughly 3,550 students per year. Since 2022, the average annual loss has jumped to 6,014, a 1.7x acceleration. The 2024-25 loss of 8,121 students was the second-largest non-COVID decline in the dataset.

Fewer babies, fewer kindergartners

The primary driver is demographic. Wisconsin recorded 59,675 births in 2024, the lowest since before World War II and an 18% decline from the 2007 birth peak. In 29 of the state's 46 rural counties, deaths now outnumber births, meaning there is no natural population replacement feeding local schools.

The birth decline flows into kindergarten classrooms with a five-year lag. That pipeline is visible in the data: kindergarten enrollment across Wisconsin has fallen steadily, and the state's K-to-12th-grade ratio has inverted, meaning 12th grade classes are now larger than entering kindergarten cohorts. Each graduating class leaves behind a smaller replacement.

School choice is a contributing factor, though its exact enrollment impact is harder to isolate. Wisconsin operates the nation's oldest voucher program, with more than 60,000 students now using vouchers across four programs, and open enrollment transfers send $8,618 per student to receiving districts with no statewide cap. Both mechanisms move students out of traditional public school enrollment counts without creating new students. The question is whether choice programs accelerate the decline or simply redistribute it.

68 of 72 counties losing students

The losses are not confined to Milwaukee or the state's urban centers. In 2025-26, 68 of Wisconsin's 72 counties saw enrollment decline, according to data analyzed by WPR and the Wisconsin Policy Forum. Of 441 districts with year-over-year data, 282 (63.9%) lost students, while only 154 gained.

Of 446 districts with 2025 data, 174 (39.0%) sit at an all-time enrollment low. The list includes nine of the state's 10 largest districts: Milwaukee, Green Bay^↗, Kenosha^↗, Racine, Appleton^↗, Waukesha^↗, Eau Claire^↗, Janesville^↗, and Oshkosh^↗.

Milwaukee alone accounts for 37.6% of the state's total enrollment loss from peak, shedding 26,219 students since 2006, a 28.6% decline. Beloit^↗ has lost 32.3% of its enrollment. West Allis-West Milwaukee^↗ has lost 33.1%.

The few districts gaining enrollment are disproportionately suburban rings and virtual school hosts. Sun Prairie^↗ added 185 students in 2025, and McFarland gained 282, though McFarland's growth is partly attributable to the Wisconsin Virtual Academy (WIVA), which draws students statewide. Middleton-Cross Plains added 108. The pattern is consistent across states: suburban districts near employment centers grow while urban cores and rural communities shrink.

The funding squeeze

Every lost student carries a budget consequence. Wisconsin's school funding formula ties state aid and local revenue authority directly to enrollment counts. Districts that lose students lose revenue, but fixed costs for buildings, transportation, and administration do not shrink proportionally.

The structural pressure is compounded by Wisconsin's revenue limit system, which has been decoupled from inflation since 2009. Districts cannot raise revenue above their cap without voter approval, which has turned school referendums into a near-annual survival exercise. In 2024, Wisconsin voters saw a record number of school referendums on their ballots, and 72 more districts are going to referendum in April 2026, seeking just over $1 billion from taxpayers.

"If we don't pass a referendum, we are going to cut $13 million from our budget next year. And that's a lot of services for kids." — Greg Hartjes, Appleton Area superintendent, Wisconsin Watch, March 2026

Appleton, the state's fifth-largest district, has lost 1,379 students from its 2015 peak and fell another 236 in 2025 alone. The Appleton referendum is not about growth or improvement. It is about keeping the lights on.

The consolidation question is becoming unavoidable. More than half of Wisconsin's 421 school districts serve fewer than 1,000 students. Republican legislators introduced six bills in November 2025 to encourage mergers, including a one-time payment of $2,000 per pupil for districts that consolidate by 2028. Despite this, only five consolidations have occurred in the past 20 years.

No bottom in sight

The cumulative loss since 2014 now stands at 66,839 students. Nothing in the demographic pipeline suggests a reversal. Wisconsin's birth rate has been below replacement level since 1974, and over 93% of the state's population growth in 2023 came from net migration, not births. Even if migration brings new families, they must arrive in numbers sufficient to offset the structural birth deficit, and many of them choose private or voucher-funded schools.

The kindergarten cohort entering in fall 2026 was born in 2020-21, the year Wisconsin births hit their modern nadir. At the current pace, the state will drop below 800,000 students by 2026-27 — a threshold no amount of referendum spending or consolidation incentive can reverse. Appleton needs $13 million just to avoid cuts. Seventy-two districts are asking taxpayers for over $1 billion in April. And in the Northwoods, where deaths already outnumber births in 29 of 46 rural counties, the buildings are getting emptier whether the referendums pass or not.
