union power

Gutting Wisconsin teachers unions hurt students, study finds

The high-profile fight to limit union power was replete with drama — including a recall election and state legislators fleeing to neighboring states.

In the 2011 battle in Wisconsin, Republican Gov. Scott Walker ultimately came out the victor. The controversial law passed, Walker won the recall, and the Democratic-aligned unions have lost much of their power.

But new research points to other losers in the fight: students in the state’s already struggling schools.

The first study to assess how Wisconsin’s high-profile weakening of unions, particularly teachers unions, affected students finds that it led to a substantial decline in test scores.

The findings come as the U.S. Supreme Court is set to hear arguments for a case, known as Janus, that could dramatically scale back union power across the country — essentially taking aspects of the Wisconsin model national. And they give credence to concerns from unions and their defenders that weakening teachers bargaining power would ultimately make schools worse, not better.

A report from the left-leaning Center for American Progress released Wednesday highlights this research — and the fact that teacher pay and average experience declined in the wake of the law, known as Act 10 — to argue that weakening unions ultimately harm schools.

“Those concerned about the quality of public education — and of all public services — should understand that Wisconsin’s Act 10 and associated budget cuts have not had the positive impact on education that its proponents claimed it would,” the CAP report argues.

Still, the research, which has not been formally peer-reviewed, only assesses the short-term impact of Wisconsin’s law. It adds to a complicated set of research findings on unions that doesn’t render a clear verdict.

Short-term effect in Wisconsin is negative, especially for low-achieving schools

The new research looks at the effects of Wisconsin Act 10, which became law in 2011 and severely limited the scope of collective bargaining and allowed members to opt out of unions.

The paper’s author, Jason Baron, took advantage of what was essentially a natural experiment set up by the law. Act 10 did not affect all school districts at once — a handful of school districts were allowed to maintain union rules until their existing contract expired up to two years later. That helped isolate the immediate impact of the law.

Baron found that weakening unions led to declines in test scores, particularly in math and science. The effects were fairly large, comparable to sharply increasing class sizes. And the harm was not evenly distributed: Schools that started out furthest behind were hurt the most, while higher achieving schools saw no impact.

Other research may help explain why.

The law led to big cuts in teacher compensation, particularly for veteran teachers and especially in health insurance and retirement benefits, according to one paper. There was also a spike in teacher retirement immediately following the law’s passage.

As compensation drops, it may become harder for district and teachers to recruit and keep teachers. An increase in retirement also reduces teacher experience, which has been linked to effectiveness.

Another study found that some Wisconsin districts moved from a single salary schedule to a performance-based pay system after Act 10’s passage. Those performance pay systems were more likely to be adopted by higher-achieving districts, potentially allowing them to lure effective teachers away from struggling schools.

“Following Act 10, high-performing schools filled vacancies from teacher retirements by poaching high-quality teachers from low-performing schools through attractive compensation schemes,” the paper concludes. So while those retirements might have hit all districts equally, high-performing districts were better able to make up the difference — at the expense of low-performing schools.

There is one study that complicates the narrative in Wisconsin. As retirements spiked, it found that academic achievement actually increased in the grades that teachers left. It’s not clear what explains this.

The larger question of how teachers unions affect learning remains up for debate

A number of other recent studies have examined the relationship between teachers unions and student outcomes outside of Wisconsin. The results aren’t consistent, but the trend has been more positive for unions of late. A caveat: Some of these studies have not been published in peer-reviewed academic journals.

  • On recent efforts to weaken unions: Research in Tennessee found that it led to a drop in teacher pay, but had no effect on student test scores. But a study of four states, including Wisconsin, that recently weakened unions found evidence of reduced teacher quality as a result.
  • On what happens when charter schools unionize: Two studies in California came to differing conclusions. One found that when charters unionize, student test scores go up, but the other showed no impact.
  • On the initial rise of collective bargaining: Another paper finds that students who went to schools where districts negotiated with unions earned less money and were more likely to be unemployed as adults. But this study looks at a fairly old data set — examining those who attended schools between 1965 and 1992.

Meanwhile, it’s not clear if any of this research is likely to influence the Supreme Court, as it considers the Janus case that could make life more difficult for unions. Last month, Chief Justice John Roberts called empirical studies on political gerrymandering “sociological gobbledygook.”

Are Children Learning

Second study shows Indianapolis charter students fare better on tests

The second study in a week shows strong test scores for students at Indianapolis charter schools, bolstering the claims of advocates in a city where school choice continues to expand.

Indianapolis elementary students who attend mayor-sponsored charter schools beginning in kindergarten — and remain in the same schools — make bigger improvements on state tests than their peers in traditional schools across the city, according to the latest study.

The study contributes to emerging research that suggest that charter schools that are well managed and have good instruction can be successful, said co-author Hardy Murphy, a clinical professor of educational leadership and policy studies at the IUPUI School of Education.

The results of the study indicate Indianapolis charter school students are doing better than they would’ve done if they hadn’t enrolled in charter schools, Murphy said.

“This does not appear to have happened by chance,” he said. “I believe that the school experiences and the instructional teachers of those schools they are enrolled in are actually a big part of the results that we are seeing,”

The educational landscape in Indianapolis is defined by school choice. About 18,000 students who live in Marion County attend charter schools, and thousands more transfer to nearby districts or attend private schools with vouchers, according to state data. In recent years, the state’s largest district, Indianapolis Public Schools, has also become a national model for partnerships with charter schools. That makes understanding school performance essential for parents — but unpacking whether schools actually help boost student achievement can be particularly thorny for researchers.

With this study, Murphy said he and co-author Sandi Cole, director of the Center on Education and Lifelong Learning at Indiana University Bloomington, hope to disentangle one factor that makes studying charter schools difficult: the dips in test scores that students often experience after transferring to new schools. Murphy’s research focuses on students who began in charter schools in kindergarten and compares them to similar students in traditional public schools in Indianapolis.

“It’s time to move beyond the debate about whether or not charter schools are effective and start talking about, when they are effective, why, and for whom?” Murphy said, adding that successful approaches can be used in other settings.

The study focuses solely on students who attend charter schools authorized by the mayor’s office. For the control group, the study included township districts as well as Indianapolis Public Schools. The researchers plan to present their results to the education committee of the Indianapolis City-County Council and the 2019 Conference on Academic Research in Education.

The findings add to a growing body of research on Indianapolis charter schools. Last week, the Stanford-based group CREDO released a report that found that students at charter schools had test score gains that mirrored the state average, while Indianapolis Public Schools students made smaller gains on math and reading tests than their peers across the state. Another recent study found that when students moved to charter schools their test scores held steady.

To Do

Tennessee’s new ed chief says troubleshooting testing is first priority

Penny Schwinn knows that ensuring a smooth testing experience for Tennessee students this spring will be her first order of business as the state’s new education chief.

Even before Gov.-elect Bill Lee announced her hiring on Thursday, she was poring over a recent report by the state’s chief investigator about what went wrong with TNReady testing last spring and figuring out her strategy for a different outcome.

“My first days will be spent talking with educators and superintendents in the field to really understand the scenario here in Tennessee,” said Schwinn, who’s been chief deputy commissioner of academics in Texas since 2016.

“I’ll approach this problem with a healthy mixture of listening and learning,” she added.

Schwinn’s experience with state assessment programs in Texas and in Delaware — where she was assistant secretary of education — is one of the strengths cited by Lee in selecting her for one of his most critical cabinet posts.

The Republican governor-elect has said that getting TNReady right is a must after three straight years of missteps in administration and scoring in Tennessee’s transition to online testing. Last year, technical disruptions interrupted so many testing days that state lawmakers passed emergency legislation ordering that poor scores couldn’t be used to penalize students, teachers, schools, or districts.

Schwinn, 36, recalls dealing with testing headaches during her first days on the job in Texas.

“We had testing disruptions. We had test booklets mailed to the wrong schools. We had answer documents in testing booklets. We had online administration failures,” she told Chalkbeat. “From that, we brought together teachers, superintendents, and experts to figure out solutions, and we had a near-perfect administration of our assessment the next year.”

What she learned in the process: the importance of tight vendor management, including setting clear expectations of what’s expected.

She plans to use the same approach in Tennessee, working closely with people in her new department and Questar Assessment, the state’s current vendor.

“Our job is to think about how to get online testing as close to perfect as possible for our students and educators, and that is going to be a major focus,” she said.

The test itself has gotten good reviews in Tennessee; it’s the online miscues that have many teachers and parents questioning the switch from paper-and-pencil exams. Schwinn sees no choice but to forge ahead online and is quick to list the benefits.

“If you think about how children learn and access information today, many are getting that information from hand-held devices and computers,” she said, “so reflecting that natural experience in our classrooms is incredibly important.”

Schwinn said computerized testing also holds promise for accommodating students with disabilities and provides for a more engaging experience for all students.

“When you look at the multiple-choice tests that we took in school and compare that to an online platform where students can watch videos, perform science experiments, do drag-and-drop and other features, students are just more engaged in the content,” she said.

“It’s a more authentic experience,” she added, “and therefore a better measure of learning.”

Schwinn plans to examine Tennessee’s overall state testing program to look for ways to reduce the number of minutes dedicated to assessment and also to elevate transparency.

She also will oversee the transition when one or more companies take over the state’s testing program beginning next school year. Former Commissioner Candice McQueen ordered a new request for proposals from vendors to provide paper testing for younger students and online testing for older ones. State officials have said they hope to award the contract by spring.

In Texas, a 2018 state audit criticized Schwinn’s handling of two major education contracts, including a no-bid special education contract that lost the state more than $2 million.

In Tennessee, an evaluation committee that includes programmatic, assessment, and technology experts will help to decide the new testing contract, and state lawmakers on the legislature’s Government Operations Committee plan to provide another layer of oversight.

Spring testing in Tennessee is scheduled to begin on April 15. You can learn more about TNReady on the state education department’s website.
