Trump education nominee pleads ignorance about high-profile voucher studies showing negative results

At his confirmation hearing, Mick Zais, the nominee to be second-in-command at the Department of Education, said that he was not aware of high-profile studies showing that school vouchers can hurt student achievement.

It was a remarkable acknowledgement by Zais, who said he supports vouchers and would report to Education Secretary Betsy DeVos, whose signature issue has been expanding publicly funded private school choice programs.

The issue was raised by Minnesota Sen. Al Franken, who asked whether Zais, who was previously the South Carolina schools chief, was “aware of the research on the impact of vouchers on student achievement.”

He replied: “To the best of my knowledge, whenever we give parents an opportunity to choose a school that’s a good fit for their child the result is improved outcomes.”

Franken responded, “No, that’s not true. The academic outcomes for students who used vouchers to attend private school are actually quite abysmal.”

Franken proceeded to mention recent studies from Louisiana, Indiana, Ohio, and Washington, DC that showed declines in test scores after students move to private schools with a voucher.

Zais responded: “Senator, I was unaware of those studies that you cited.”

Franken then asked if Zais’s initial response expressing confidence in school choice was anecdotal, and Zais said that it was.

What’s surprising about Zais’s response is that these studies were not just published in dusty academic journals, but received substantial media attention, including in the New York Times and Washington Post (and Chalkbeat). They’ve also sparked significant debate, including among voucher supporters, who have argued against judging voucher programs based on short-term test scores.

Meanwhile, it’s worth noting that the research confusion was a bipartisan affair at Wednesday’s confirmation hearing.

Although Franken, who referred to a New York Times article on voucher research in his question, was broadly accurate in his description of the recent studies, he said that a DC voucher study showed “significantly lower math and reading scores”; in fact, the results were only statistically significant in math, not reading.

Franken also did not mention evidence that the initial negative effects abated in later years in Indiana and for some students in Louisiana, or discuss recent research linking Florida’s voucher-style tax credit program to higher student graduation rates.

In a separate exchange, Washington Sen. Patty Murray grilled Jim Blew — the administration’s nominee for assistant secretary for planning, evaluation, and policy development — on the performance of Michigan’s charter schools. Murray said that DeVos was “one of the architects of Detroit’s charter school system,” describing the results as “disastrous for children.”

Blew disputed this: “The characterization of the charter school sector in Detroit as being a disaster seems unfair. The most reliable studies are saying, indeed, the charter school students outperform the district students.”

Murray responded: “Actually, Michigan’s achievement rates have plummeted for all kids. In addition, charter schools in Michigan are performing worse than traditional public schools.”

(Murray may be referring to an Education Trust analysis showing that Michigan ranking on NAEP exams have fallen relative to other states. The study can’t show why, or whether school choice policies are the culprit, as some have claimed.)

Blew answered: “The most reliable studies do show that the charter school students in Detroit outperform their peers in the district schools.”

Murray: “I would like to see that because that’s not the data that we have.”

Blew: “I will be happy to get if for you; it’s done by the Stanford CREDO operation.”

Murray: “I’m not aware of that organization.”

CREDO, a Stanford-based research institution, has conducted among the most widely publicized — and sometimes disputed — studies of charter schools. The group’s research on Detroit does show that the city’s charter students were outperforming similar students in district schools, though the city’s students are among the lowest-performing in the country on national tests.

Why the school spending graph Betsy DeVos is sharing doesn’t mean what she says it does

U.S. Secretary of Education Betsy DeVos’s message at an event on Thursday was clear: education leaders have been throwing good money after bad policy.

To make the point, she shared a graph that appears to show that school spending has risen dramatically over the last three decades as student outcomes barely budged.

“Scores [are] continuing to muddle along, unremarkable,” she told one of her predecessors, Bill Bennett, at a Reagan Institute event. “And yet look at the spending. This is not something we’re going to spend our way out of.”

This visualization, which DeVos also shared on Twitter, has become a staple in some education policy circles. Even Bill Gates has offered a version of it. But the graph is misleading, and several recent studies have in fact shown that students gain — in higher test scores, graduation rates, and earnings as adults — when they attend schools that spend more money. And while DeVos highlighted scores in reading, gains in math have been fairly substantial over part of that period.

A spokesperson for DeVos did not immediately respond to a request for additional comment.

Here’s why it doesn’t really mean what DeVos says it does.

The biggest problem with the graphic is that it conflates correlation and causation.

Simply pointing to two trends that coincide doesn’t say anything about how one affects the other. It’s possible that if education spending hadn’t increased, test scores would have actually declined. Maybe the extra money actually stopped a dramatic deterioration in school quality, for example. There’s just no way to know based on this data.

Here’s another example: Over the past couple decades, charter schools and vouchers have expanded dramatically. By DeVos’s own logic, those would be failed reforms because they didn’t coincide with a sufficient increase in NAEP scores. But that would also be an unfair conclusion, since we don’t know what would have happened without the increase in choice programs.

The two trends are also put side-by-side in an arbitrary way.

This graph has two y axes: one based on school spending, and the other based on scale scores on the National Assessment of Educational Progress. But these two variables are very different. Should an extra $1,000 correspond with 1 point on NAEP scores? Five points?

The decision is subjective, but it determines how large the spending changes look and how small the NAEP changes look, too.

Spending is up in education, but it’s up elsewhere too.

It’s true that in inflation-adjusted dollars, school spending has risen. The economy has also grown over that same time. That matters, because if spending were to hold steady in education while increasing in other areas of the economy, it might become increasingly hard to recruit and retain teachers of equal quality.

Indeed, while education spending has risen, teacher pay compared to similar professionals has fallen. (At the same time, the number of teachers and the number of non-teaching staff in schools has increased significantly, which some have argued illustrate bad spending priorities.)

The story would also look different for math scores.

NAEP scores have been relatively flat for the past decade, but in math they increased substantially the decade beforehand. In fact, a graph could be made showing a tight correspondence between math results and spending.

That’s exactly what Northwestern University economist Kirabo Jackson did. His approach was similar to DeVos’s, with a few changes. He compared NAEP scores in math to the cumulative spending on the average student in the years leading up to the test — the idea being that scores reflect not just the last year of schooling, but several years before that.

His graphs look quite different than DeVos’s, simply by tightening the range of scores, looking at math rather than reading, and tweaking the spending measure. (Jackson said that a similar pattern exists for reading, but that it’s less pronounced.)

Recent research has generally shown that school spending really does matter.

To be clear, Jackson’s graphs are also correlational, and like DeVos’s cannot prove cause and effect.

That’s why he and others have conducted sophisticated statistical analyses to isolate the impact of resources on schools. In one recent study, Jackson and colleagues compared states that made more spending cuts in the wake of Great Recession, and found that they did worse on NAEP as a result. In other words, there is a decent case that the recent stagnation in NAEP scores is due at least in part to spending cuts.

That jibes with a larger body of research. Other recent national studies have linked more spending to better NAEP scores, higher graduation rates, better economic outcomes, and greater social mobility. Studies in specific states including California, MassachusettsOhio, and New York have also found test score gains from spending increases.

Of course, none of that proves that the additional money spent over the past few decades have been well used. It doesn’t even prove that those extra dollars have been helpful — the above studies are of specific places or time periods, and their individual approaches could be disputed, too.

There is one recent study, which DeVos often cites, showing that a federal turnaround program that involved a substantial infusion of money for struggling schools didn’t make a noticeable difference.

Still, the graph that Devos offers is not, on its own, a strong case that resources for schools don’t make a difference. Available evidence suggests the opposite.

“If reduced spending contributed to the problem, it seems reasonable to conclude that increased spending may alleviate it,” said Jackson, the Northwestern researcher. “This is not to say that increased spending is some silver bullet, but rather that it should probably be part of a comprehensive set of policies to improve U.S schools.”

Betsy DeVos avoids questions on discrimination as school safety debates reach Congress

U.S. Education Secretary Betsy DeVos fielded some hostile questions on school safety and racial discrimination as she defended the Trump administration’s budget proposal in a House committee hearing on Tuesday.

The tone for the hearing was set early by ranking Democrat Rep. Rosa DeLauro, who called aspects DeVos’s prepared remarks “misleading and cynical” before the secretary had spoken. Even the Republican subcommittee chair, Rep. Tom Cole, expressed some skepticism, saying he was “concerned about the administration continuing to request cuts that Congress has rejected.”

During nearly two hours of questioning, DeVos stuck to familiar talking points and largely side-stepped the tougher queries from Democrats, even as many interrupted her.

For instance, when Rep. Barbara Lee, a Democrat from California, complained about proposed spending cuts and asked, “Isn’t it your job to ensure that schools aren’t executing harsher punishments for the same behavior because [students] are black or brown?” DeVos responded by saying that students of color would benefit from expanded school choice programs.

Lee responded: “You still haven’t talked about the issue in public schools as it relates to black and brown students and the high disparity rates as it relates to suspensions and expulsions. Is race a factor? Do you believe that or not?” (Recent research in Louisiana found that black students receive longer suspensions than white students involved in the same fights, though the difference was very small.)

Again, DeVos did not reply directly.

“There is no place for discrimination and there is no tolerance for discrimination, and we will continue to uphold that,” she said. “I’m very proud of the record of the Office of Civil Rights in continuing to address issues that arise to that level.”

Lee responded that the administration has proposed cuts to that office; DeVos said the reduction was modest — less than 1 percent — and that “they are able to do more with less.”

The specific policy decision that DeVos faces is the future of a directive issued in 2014 by the Obama administration designed to push school districts to reduce racial disparities in suspensions and expulsions. Conservatives and some teachers have pushed DeVos to rescind this guidance, while civil rights groups have said it is crucial for ensuring black and Hispanic students are not discriminated against.

That was a focus of another hearing in the House on Tuesday precipitated by the shooting last month at Marjory Stoneman Douglas High School in Parkland, Florida.

Rep. Jim Sensenbrenner, a Wisconsin Republican, falsely claimed in his opening statement that Broward County Public Schools rewrote its discipline policy based on the federal guidance — an idea that has percolated through conservative media for weeks and been promoted by other lawmakers, including Florida Sen. Marco Rubio and Utah Sen. Mike Lee. In fact, the Broward County rules were put into place in 2013, before the Obama administration guidance was issued.

The Manhattan Institute’s Max Eden, a leading critic of Obama administration’s guidance, acknowledged in his own testimony that the Broward policy predated these rules. But he suggested that policies like Broward’s and the Obama administration’s guidance have made schools less safe.

“Faced with pressure to get the numbers down, the easiest path is to simply not address, or to not record, troubling, even violent, behavior,” he said.

Kristen Harper, a director with research group Child Trends and a former Obama administration official, disagreed. “To put it simply, neither the purpose nor the letter of the federal school discipline guidance restrict the authority of school personnel to remove a child who is threatening student safety,” she said.

There is little, if any, specific evidence linking Broward County’s policies to how Stoneman Douglas shooter Nicholas Cruz was dealt with. There’s also limited evidence about whether reducing suspensions makes schools less safe.

Eden pointed to a study in Philadelphia showing that the city’s ban on suspensions coincided with a drop in test scores and attendance in some schools. But those results are difficult to interpret because the prohibition was not fully implemented in many schools. He also cited surveys of teachers expressing concerns about safety in the classroom including in Oklahoma CityFresno, California; and Buffalo, New York.

On the other hand, a recent study found that after Chicago modestly reduced suspensions for the most severe behaviors, student test scores and attendance jumped without any decline in how safe students felt.

DeVos is now set to consider the repeal of those policies on the Trump administration’s school safety committee, which she will chair.

On Tuesday, DeVos said the committee’s first meeting would take place “within the next few weeks.” Its members will be four Cabinet secretaries: DeVos herself, Attorney General Jeff Sessions, Secretary of Health and Human Services Alex Azar, and Secretary of Homeland Security Kirstjen Nielsen.

Correction: An earlier version of this story said that Rep. Barbara Lee was from Texas; in fact, she represents a California congressional district.
