a failure of accountability

High-stakes testing may push struggling teachers to younger grades, hurting students

Kindergarten, first grade, and second grade are often free of the high-stakes testing common in later grades — but those years are still high-stakes for students’ learning and development.

That means it’s a big problem when schools encourage their least effective teachers to work with their youngest students. And a new study says that the pressure of school accountability systems may be encouraging exactly that.

“Evidence on the importance of early-grades learning for later life outcomes suggests that a system that pushes schools to concentrate ineffective teachers in the earliest grades could have serious unintended consequences,” write study authors Jason Grissom of Vanderbilt and Demetra Kalogrides and Susanna Loeb of Stanford.

The research comes at an opportune time. All 50 states are in the middle of crafting new systems designed to hold schools accountable for student learning. And this is just the latest study to point out just how much those systems matter — for good and for ill.

The study, published earlier this month in the peer-reviewed American Educational Research Journal, focuses on Miami-Dade County schools, the fourth-largest district in the country, from 2003 to 2014. Florida had strict accountability rules during that period, including performance-based letter grades for schools. (Those policies have been promoted as a national model by former Florida Governor Jeb Bush and his national education reform outfit, where Education Secretary Betsy DeVos previously served on the board.)

The trio of researchers hypothesized that because Florida focuses on the performance of students in certain grades and subjects — generally third through 10th grade math and English — less-effective teachers would get shunted to other assignments, like early elementary grades or social studies.

That’s exactly what they found.

In particular, elementary teachers effective at raising test scores tended to end up teaching grades 3-6, while lower-performing ones moved toward early grades.

While that may have helped schools look better, it didn’t help students. Indeed, the study finds that being assigned a teacher in early elementary school who switched from a higher grade led to reduced academic achievement, effects that persisted through at least third grade.

The impact was modest in size, akin to being assigned a novice teacher as opposed to a more experienced one.

The study is limited in that it focuses on just a single district, albeit a very large one — a point the authors acknowledge. Still, the results are consistent with past research in North Carolina and Florida as a whole, and district leaders elsewhere have acknowledged responding to test pressure in the same way.

“There was once upon a time that, when the test was only grades 3 through 12, we put the least effective teachers in K-2,” schools chief Sharon Griffin of Shelby County schools in Memphis said earlier this year. “We can’t do that anymore. We’re killing third grade and then we have students who get in third grade whose challenges are so great, they never ever catch up.”

While the Florida study can’t definitively link the migration of teachers to the state’s accountability system, evidence suggests that it was a contributing factor.

For one, the pattern is more pronounced in F-rated schools, which face the greatest pressure to raise test scores. The pattern is also stronger when principals have more control over staffing decisions — consistent with the idea that school leaders are moving teachers around with accountability systems in mind.

Previous research of policies like No Child Left Behind that threaten to sanction schools with low test scores have found both benefits and downsides. On the positive side, accountability can lead to higher achievement on low-stakes exams and improved instruction; studies of Florida’s system, in particular, have found a number of positive effects. On the negative side, high-stakes testing has caused cheating, teaching to the test, and suspensions of students unlikely to test well.

So how can districts avoid the unintended consequences for young students documented by the Miami-Dade study?

One idea is to emphasize student proficiency in third grade, a proxy for how well schools have taught kids in kindergarten, first and second grades.

Scholars generally say that focusing on progress from year to year is a better gauge of school effectiveness than student proficiency. But a heavily growth-based system could actually give schools an incentive to lower student achievement in early grades.

“These results do make an argument for weighting [proficiency] in those early tests to essentially guard against totally ignoring those early grades,” said Grissom, who also noted that states could make more efforts to directly measure performance of the youngest students.

But Morgan Polikoff, an associate professor at the University of Southern California, was more skeptical of this approach.

“It’s not as if states are going to add grades K-2 testing, so schools and districts will always have this incentive (or think they do),” he told Chalkbeat in an email. “I think measurement is always going to be an issue in those early grades.”

Most Tennessee districts are showing academic growth, but districts with the farthest to go improved the least

It’s not just Memphis: Across Tennessee, districts with many struggling schools posted lower-than-expected growth scores on this year’s state exams, according to data released Tuesday.

The majority of Tennessee’s 147 districts did post scores that suggest students are making or exceeding expected progress, with over a third earning the top growth score.

But most students in three of the state’s four largest districts — in Memphis, Nashville and Chattanooga — aren’t growing academically as they should, and neither are those in most of their “priority schools” in the state’s bottom 5 percent.

The divide prompted Education Commissioner Candice McQueen to send a “good news, bad news” email to superintendents.

“These results point to the ability for all students to grow,” she wrote of the top-performing districts, many of which have a wide range of academic achievement and student demographics.

Of those in the bottom, she said the state would analyze the latest data to determine “critical next steps,” especially for priority schools, which also are located in high-poverty communities.

“My message to the leaders of Priority schools … is that this level of growth will never get kids back on track, so we have to double-down on what works – strong instruction and engagement, every day, with no excuses,” McQueen said.

Growth scores are supposed to take poverty into account, so the divide suggests that either the algorithm didn’t work as it’s supposed to or, in fact, little has happened to change conditions at the state’s lowest-performing schools, despite years of aggressive efforts in many places.

The results are bittersweet for Tennessee, which has pioneered growth measures for student learning and judging the effectiveness of its teachers and schools under its Tennessee Value-Added Assessment System, known as TVAAS.

On the one hand, the latest TVAAS data shows mostly stable growth through the transition to TNReady, the state’s new test aligned to new academic standards, in the first year of full testing for grades 3-11. On the other hand, Tennessee has invested tens of millions of dollars and years of reforms toward improving struggling schools — all part of its massive overhaul of K-12 education fueled by its 2009 federal Race to the Top award.

The state-run Achievement School District, which launched in the Race to the Top era to turn around the lowest-performing schools, saw a few bright spots, but almost two-thirds of schools in its charter-reliant portfolio scored in the bottom levels of student growth.

Shelby County’s own turnaround program, the Innovation Zone, fared poorly too, with a large percentage of its Memphis schools scoring 1 on a scale of 1 to 5, after years of scoring 4s and 5s.


District profile: Most Memphis schools score low on student growth


Superintendent Dorsey Hopson called the results a “wakeup call” for the state’s biggest district in Memphis.

“When you have a population of kids in high poverty that were already lagging behind on the old, much easier test, it’s not surprising that we’ve got a lot of work to do here,” he said, citing the need to support teachers in mastering the state’s new standards.

“The good part is that we’ve seen the test now and we know what’s expected. The bad part is we’ve seen the test … and it’s a different monster,” he told Chalkbeat.

Most Memphis schools score low on student growth under new state test

More than half of Memphis schools received the lowest possible score for student growth on Tennessee’s new test last school year, according to data obtained by Chalkbeat for Shelby County Schools.

On a scale of 1 to 5, with 1 being the lowest measure, about 54 percent of the district’s 187 schools scored in the bottom rung of the Tennessee Value-Added Assessment System, known as TVAAS.

That includes most schools in the Innovation Zone, a reversal after years of showing high growth in the district’s prized turnaround program.

Charter schools fared poorly as well, as did schools that were deemed among the state’s fastest-improving in 2015.

Superintendent Dorsey Hopson called the scores a “huge wakeup call.”

“It shows that we’ve got a tremendous amount of work to do,” Hopson told Chalkbeat on Monday. “It’s going to be hard and it’s going to be frustrating. … It starts with making sure we’re supporting teachers around mastering the new standards.”

District leaders across Tennessee have been trying to wrap their heads around the latest growth scores since receiving the data in late August from the State Department of Education. Only two years earlier, the Memphis district garnered the highest possible overall growth score. But since then, the state has switched to a harder test called TNReady that is aligned for the first time to more rigorous academic standards.

TVAAS results are scheduled to be released publicly this week, but Chalkbeat obtained a copy being circulated within Shelby County Schools, Tennessee’s largest district.

The data is prompting questions from some Memphis educators — and assurances from state officials — over the validity of TVAAS, the state’s system for measuring learning and judging the effectiveness of its teachers and schools.

This is the first year of issuing district-wide TVAAS scores since 2015. That’s because of the state’s cancellation of 2016 testing for grades 3-8 due mostly to failures in the switch to online testing.

Some educators wonder whether the bumpy switch to TNReady is a factor in this year’s nosedive, along with changes in how the scores are calculated.

For example, data for fourth-graders is missing since there is no prior state testing in third grade for comparison. Elementary and middle schools also don’t have growth scores for social studies, since the 2017 questions were a trial run and the results don’t count toward a school’s score.

Hopson acknowledged concerns over how the state compares results from “two very different tests which clearly are apples and oranges,” but he added that the district won’t use that as an excuse.

“Notwithstanding those questions, it’s the system upon which we’re evaluated on and judged,” he said.

State officials stand by TVAAS. They say drops in proficiency rates resulting from a harder test have no impact on the ability of teachers, schools and districts to earn strong TVAAS scores, since all students are experiencing the same change.

“Because TVAAS always looks at relative growth from year to year, not absolute test scores, it can be stable through transitions,” said Sara Gast, a spokeswoman for the State Department of Education.

Shelby County Schools is not the only district with disappointing TVAAS results. In Chattanooga, Hamilton County Schools logged low growth scores. But Gast said that more districts earned average or high growth scores of 3, 4 or 5 last school year than happened in 2015.

Below is a breakdown of Shelby County’s TVAAS scores. A link to a school-by-school list of scores is at the bottom of this story.

Districtwide

School-wide scores are a combination of growth in each tested subject: literacy, math, science and social studies.

Fifty three schools saw high growth in literacy, an area where Shelby County Schools has doubled down, especially in early grades. And 51 schools saw high growth in math.

Note: A TVAAS score of 3 represents average growth for a student in one school year. A score of 1 represents significantly lower academic growth compared to peers across the state.
