🛝 The Yardstick Moved, Not the Students

Welcome to Playground Post, a bi-weekly newsletter that keeps education innovators ahead of what's next.

This week's reality check: Brookings looked at nearly 50 years of school spending data and found the poorest districts have outspent the wealthiest since the early 2000s. AP pass rates jumped as much as 21 points in a single year, right after the College Board changed how the exams are scored. And in a study of 1.74 million California students, even the kids who failed dual enrollment went on to college more often than the kids who never tried it.

Data Gem

Just 12% of American adults rate four-year colleges "good" or "excellent" on affordability, versus 54% for community colleges, according to Lumina Foundation and Gallup polling.

The Poorest Districts Outspend the Richest

The most repeated claim in American education finance goes like this: schools run on local property taxes, so poor districts get less money, and that gap drives unequal outcomes.

Brookings checked the data. Nearly 50 years of it, from Census Bureau surveys of district spending and enrollment, across all 50 states.

The claim is backwards.

Sorted into five poverty quintiles, per-student spending traces a U-shape, with the poorest and wealthiest districts spending the most. 

And since the early 2000s, the poorest districts have outspent even the wealthiest ones.

Within states, predominantly non-white districts have had more funding than their counterparts across the entire five-decade period studied.

States target money to high-poverty districts, and federal funding adds more: Title I alone sent $18.4 billion to schools with high concentrations of low-income students this year.

"That doesn't mean giving poor schools more money wouldn't help. It could help," said Sarah Reber, the Brookings senior fellow who led the study. But "if we're spending all of our time … focused on the level and allocation of school funding, we're missing other important things."

High-poverty urban districts face higher labor costs that eat part of the spending advantage. Causal research still shows added funding improves outcomes. 

And the targeted state money proved fragile: it left those same districts most exposed to cuts during the Great Recession.

So what about the famous finding that white districts get $23 billion more? 

The two studies measure different things. 

EdBuild adjusted for regional costs and counted only state and local revenue; Brookings counted total spending, including the federal dollars that flow disproportionately to non-white districts. "There are different ways to accurately measure whether or not kids are getting their fair share," said Rebecca Sibilia, who led EdBuild when its report came out.

The funding gap inverted two decades ago. The gaps it was supposed to explain didn't.

Which relocates the problem. "Obviously, there's places that are spending much less and not really getting demonstrably worse outcomes," Reber said. "I think it's important to try and learn from that and try to figure out what the barriers to being more productive with spending are."

For education innovators, that last sentence is the market. If the binding constraint isn't the level of funding, it's the productivity of it. Outcomes-per-dollar benchmarking that lets a district see what similar spending buys elsewhere. Resource-allocation analytics that trace dollars to instructional impact instead of line items. The debate spent 50 years arguing about how much. The tools for how well barely exist.

AP Scores Soared. The Scoring Changed First

In AP Chemistry, the share of students passing jumped from 54% in 2022 to 75.1% in 2023. 

AP U.S. Government rose from 49.2% to 73%. 

By one estimate, roughly 100,000 more students passed AP U.S. History in 2024 than the year before.

The surge arrived right after the College Board adopted a new scoring methodology in 2022, built on input from hundreds of college faculty about what their courses actually expect.

Across nine of AP's most popular subjects, the share scoring 3 or higher rose from 52% in 2021 to 71% in 2025, and top scores of 4 or 5 climbed from 28% to 45%. 

It wasn't a more selective pool: the number of test takers grew more than 10%.

For historical context, the biggest single-year change on any of those tests between 2002 and 2019 was 12.3 percentage points.

The first year under the new system, passing shares rose 17.4 points on average across all nine.

The College Board says this is a correction, not inflation. The old panels "had established artificially stringent standards that produced pass rates well below the historical AP standard," said Trevor Packer, who has led AP for over 20 years.

Critics aren't convinced. 

Harvard's Paul Peterson accused the organization of dumbing down its hallmark product. Researcher Tom Loveless points at the timing: every other major assessment shows pandemic-era declines. "Yet the AP tests are defying what every other test is telling us," he said.

Others, including test-prep founders and longtime College Board critics, find deliberate watering-down unlikely and call the recalibration reasonable.

Here's what nobody disputes: the stakes run on autopilot. 

A 3 or above generally earns college credit, and 37 states require their public universities to award it. States subsidize the $99 exam fees. Over 1.3 million students took an AP test in 2025.

Institutions are starting to react.

 In February, University of California faculty boards recommended studying the new scoring system's parameters and, if needed, reconsidering criteria for admissions, placement, and credit.

For education innovators, the uncertainty is the opening. Placement analytics that track how AP-credit students actually perform in the next course, which is the empirical answer no one has. Independent score-validation and equating services for university systems doing what UC just started.

Failing Dual Enrollment Still Beat Never Trying

Dual enrollment is the fastest-growing on-ramp to college: high schoolers taking real college courses for real credit, with states expanding access to close equity gaps.

A new Annenberg Institute working paper asked the uncomfortable question: what happens to the students who fail?

Researchers tracked 1.74 million California public high school students who entered ninth grade between 2015-16 and 2018-19. 

About 16.8% of dual enrollees failed at least one course.

Socioeconomically disadvantaged students were more likely to fail regardless of their prior achievement or preparation. 

The majority of students who failed were Hispanic, and failers skewed lower-income and male.

And failing carried a real cost: students who failed a course were considerably less likely to attend college.

Then came the finding that flips the policy debate.

Even the students who failed enrolled in college more often than students who never took a dual-enrollment course at all.

"They're gaining something … from just taking a college course," said WestEd's Jenna Howard Terrell, the study's co-principal investigator, who often hears practitioners assume a failing grade means a catastrophic outcome. The data says otherwise.

High-achieving students failed too, which undermines the standardized-test screens many programs use.

The system isn't ready. 

States have shifted eligibility from tests to grades, enrollment has surged, and pass rates haven't budged. 

A CCRC review found most states fund dual-enrollment students at lower rates than regular college students.

For education innovators, the gap between the finding and the funding is the product. Early-alert analytics for dual enrollment specifically, since struggling high schoolers sit in college courses where their own counselors can't see them.
