high-stress testing

How the stress of state testing might make it harder for some students to show what they know

The annual ritual of state testing in elementary and middle schools often comes within an unwelcome side effect: jittery, stressed-out kids.

Now, a first-of-its-kind study documents some of what’s actually happening to students.

It found that students in one New Orleans charter network saw modest spikes in cortisol, a hormone caused by stress, leading up to state exams. And the students whose cortisol spiked most or crashed furthest did worse than predicted — suggesting that the test scores reflect not just what students know, but how they perform under pressure.

The five researchers behind the study call that a “stress bias.” The paper finds some evidence that students living in higher-crime, higher-poverty neighborhoods are most affected.

That’s not surprising from a biological perspective, said Pamela Cantor, a psychiatrist and the founder of Turnaround for Children, a group that works to address the effects of trauma on children in schools.

“What we’re in effect doing to kids who are exposed to adversity on a chronic basis is actually putting them in a highly unfair situation, where their biology may overreact to the stress and not give them a very good opportunity to reveal the things they likely know,” she said.

The research looks at fewer than 100 students, and some of the findings are ambiguous. “I don’t want to make broad policy claims based on this one paper with a relatively small sample size in one setting,” said lead author Jennifer Heissel, a professor at the Naval Postgraduate School. But, she said, “if this is replicated in other settings for other students, we need to reconsider perhaps what we are using high-stakes tests for.”

The study, released earlier this month through the National Bureau of Economic Research, focuses on a network of three charter schools in New Orleans. The researchers analyzed an unusual data source: saliva samples of 93 elementary and middle students, obtained with parents’ consent, during the 2015-16 school year.

The research team compared cortisol levels of students at three points: during a regular week, a week when students took a low-stakes practice test, and the week students took the state test.

Cortisol is a hormone that generally increases after someone wakes up and declines from there. It jumps in response to stress or challenges and decreases due to boredom or disengagement.

The researchers focus on cortisol levels in the period right before the exam, when students were likely to be most be stressed about testing. Indeed, cortisol levels were about 15 percent higher at that time during testing week than they were during a regular week.

“That is in line with other stressors you might encounter through your day,” Heissel explained.

But some students responded more dramatically. “On average, there’s this increase, but individual kids are going in different directions,” she said.

Students whose cortisol noticeably spiked or dipped tended to perform worse than expected on the state test, controlling for past grades and test scores. Boys saw bigger changes than girls. and so did students from higher-poverty neighborhoods, though this difference was not statistically significant. (Keep in mind that the students in the study were almost all low-income, so there was limited room for comparison.)

It’s possible that some students’ jumps or dips in cortisol during testing week were due to other factors in their lives. But Cantor of Turnaround for Children said it’s not surprising that tests would induce stress, or that students more likely to have experienced trauma would respond differently.

“For children who face adversity in a chronic way, that system is pumped and primed much more so than other kids,” Cantor said. “If a child does overreact to a trigger, one of the ways that manifests itself is that they shut down, they freeze.”

Is that a “stress bias”? If tests unfairly penalize students who respond poorly to stress, that might suggest that “tests aren’t fully capturing what we want and perhaps what we are thinking that they capture,” said Heissel.

Another interpretation, she noted, is that the ability to perform well under pressure is part of what exams measure, and that it’s a skill “to be able to wrangle your stress response.”

The results raise a number of unanswered questions.

One is whether the results would hold for in-class exams administered by teachers. In many cases, those tests have higher stakes for students than do state exams, which in New Orleans have been used to grade and in some cases close schools.

Another is whether the way students are prepared for state exams might affect their stress. The paper offers limited information on the charter network being studied, which is anonymous. But a number of high-profile charter schools place substantial emphasis on preparation for state tests. It’s unclear whether this approach increases or reduces test-related stress.

Either way, the latest paper suggests one way to produce better scores is to ensure students stay calm during testing.

And a final question is, how else might the stress of testing affect students? Past national research offers mixed evidence on whether No Child Left Behind, the federal education law that led to the current state testing regimen, led to general increases in student anxiety.

Cantor said that the key to buffering against adversity is having warm, positive relationships, which can prompt the release of anti-stress hormones.

“A teacher who communicates belief and confidence and inspires trust in kids — that teacher is activating a hormonal system that opposes the effects of cortisol,” she said.

Class of 2018

Some Colorado schools see big gains in grad rates. Find yours in our searchable database.

Two metro-area school districts, Westminster and Aurora, recently in the state’s crosshairs for their low-performance, posted significant increases in their graduation rates, according to 2018 numbers released Wednesday.

Westminster, a district that got off the state’s watchlist just last year, had 67.9 percent of its students graduate on time, within four years of starting high school. That was a jump of 10 percentage points from its 57.8 percent graduation rate in 2017.

District officials credit their unique model of competency-based education, which does away with grade levels and requires students prove they mastered content before moving up a level. In previous years, district officials pointed to rising graduation rates that Colorado also tracks for students who take five, six or seven years, but officials say it was bound to impact their 4-year rates as well.

“We saw an upward tick across the board this past year,” said Westminster Superintendent Pam Swanson, referring to state test results and other data also showing achievement increasing. “I think this is one more indicator.”

Swanson said the high school has also focused recently on increasing attendance, now at almost 90 percent, and increasing students’ responsibility for their own learning.

In Aurora schools, 76.5 percent of students graduated on time in 2018 — a jump of almost 9 percentage points from the 67.6 percent rate of the class of 2017.

“We’re excited these rates demonstrate momentum in our work,” Aurora Superintendent Rico Munn said.

He attributed the increased graduation rates to “better practice, better pedagogy, and better policy.”

One policy that made a difference for the district is a change in law that now allows districts to count students as graduates the year they complete their high school requirements, even if they are enrolled in one of Colorado’s programs to take college courses while doing a fifth year of high school.

According to a state report two years ago, Aurora had 65 students enrolled in this specific concurrent enrollment program who previously wouldn’t have been counted in four-year graduation rates. Only the Denver district has a larger number of such students. Aurora officials said 147 students are enrolled this year in the program.

Those students are successful, Munn said, and shouldn’t be counted against the district’s on-time graduation rates.

Aurora’s previously rising graduation rates helped it dodge corrective state action. But its improvement this year included a first: One high school, Aurora West College Preparatory Academy, had 100 percent of its seniors graduate in 2018.

The school enrolls students in grades six through 12 in northwest Aurora, the most diverse part of the district. Of the more than 1,000 students, 89 percent qualify for subsidized lunch, a measure of poverty.

“This incredible accomplishment demonstrates the strong student-focused culture we have created at Aurora West,” said Principal Taya Tselolikhina in a written statement. “When you establish high expectations and follow up with high levels of support, every student is able to shape a successful future.”

Statewide, the four-year graduation rate once again inched higher, and gaps between the graduation rate of white students and students of color again decreased. But this time, the gaps narrowed even as all student groups increased their graduation rates.

The rising trend wasn’t universal. In some metro area school districts, graduation rates fell in 2018. That includes Adams 14, the district that is now facing outside management after years of low performance.

The tiny school district of Sheridan, just southwest of Denver, saw a significant drop in graduation rates. In 2018, 64.7 percent of students graduated within four years, down from 72.7 percent of the class of 2017.

School accountability

Concerned with state A-F grading system, Vitti says he’ll lobby for Detroit to keep its own plan

Detroit school district leaders will lobby state leaders to allow for a Detroit-only letter grading system to hold district and charter schools in the city accountable. But if that isn’t successful, the district plans to create its own system.

This plan, announced Tuesday night by Superintendent Nikolai Vitti, comes almost a month after lame-duck lawmakers in the Michigan Legislature passed a controversial A-F letter grading system for the whole state. A Detroit-only system would gives schools far more credit for improvement in test scores than the statewide system does, and it would account for an issue — poverty — that disproportionately affects city schools. 

That state system, which former Gov. Rick Snyder signed into law in late December, halted efforts that had already been underway by district and charter leaders to create an A-F system that takes the specific issues facing Detroit schools into account. That local system had been mandated by a 2016 law and only applied to the city.

Vitti’s announcement comes as state education officials from the Michigan Department of Education have raised concerns that the A-F system OK’d by lawmakers violates federal education law and could potentially cost the state federal money.

Vitti laid out a plan to first lobby new state leaders, including Gov. Gretchen Whitmer and the Republican leaders of the House and Senate, to allow for local grade systems.

If successful, Vitti said, that system that had been in the works would be adopted for district and charter schools.

If unsuccessful, Vitti said, the district would go it alone, without charter schools.

“We need to start thinking about our own approach to school accountability,” Vitti said.

The Community Education Commission created the letter grading system and worked for months with district and charter leaders to design a plan that would be specific to Detroit schools. The topic didn’t come up at a commission meeting Monday night until a member of the public urged the commission to move ahead with the local system and one member of the commission agreed. A commission official earlier in the day said they were still exploring how to move forward in light of the statewide system.

The city’s plan was for schools to be rewarded heavily for the amount of improvement seen in test scores. That’s important in a high-poverty community like Detroit, where most of the schools are struggling. City schools also struggle with enrollment instability.

Vitti said the statewide system “doesn’t provide much clarity on individual school performance,” because it will issue a handful of letter grades. Those letter grades will be based on the number of students proficient in reading and math on state exams, the number of students who show an adequate amount of improvement in reading and math on state exams, the number of students still learning English who show improvement in learning the language, graduation rates for high schools, and the overall academic performance of a school and how it compares to other schools in the state with similar demographics.

The Detroit system would issue a single letter grade. Vitti said a system that issues as many grades as the state system would make it “hard to distinguish one school from another.”

Board President Iris Taylor said she would support such a plan by the district, saying “it’s critical if we’re going to achieve the objectives we have laid out in the strategic plan.”

Board member Sonya Mays said one of the advantages of a statewide system is that it allows “parents to better evaluate from school to school, across districts.”

She said it’s important not to lose sight of the fact that the future of the district is to draw back 32,000 students who live in Detroit but opt to go to schools outside the city.
