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.

Innovation Zone

Out of the 23 schools in the district’s program to turn around low-performing schools, most received a growth score of 1 in 2017. That stands in stark contrast to prior years since the program opened in 2012, when most schools were on a fast growth track.

Three years in, some signs of (slight) academic growth at struggling ‘Renewal’ schools

Mayor Bill de Blasio at Brooklyn Generation School — part of the Renewal program

When Mayor Bill de Blasio launched an aggressive and expensive campaign to turn around the city’s lowest performing schools, he made a big promise: Schools would see “fast and intense” improvements within three years.

Almost exactly three years later, and after flooding 78 schools with more than $386 million in new social services and academic support, there are signs that the Renewal program has generated gains in student learning. The evidence is based on two newly updated analyses of test score data — one from Marcus Winters, a fellow at the conservative-learning Manhattan Institute, and the other from Aaron Pallas, a professor at Teachers College.

But the researchers caution that those improvements are modest — when they exist at all — and don’t yet match the mayor’s lofty promises.

The results may have implications far beyond New York City, as a national and political test case of whether injecting struggling schools with resources is more effective than closing them.

The two researchers previously reviewed the first two years of test score data in elementary and middle schools in the Renewal program: Winters found a positive effect on test scores, while Pallas generally found little to no effect.

Now, as the program reaches its third birthday, the pair of researchers have updated their findings with new test score data from last school year, and largely reaffirmed their earlier conclusions.

“We’re not seeing large increases” in student achievement, Pallas said. “And the reality is it’s hard to get large increases in struggling schools.”

Some advocates have argued that it is too early to expect big shifts in test scores, and that infusing schools with extra social services like mental health counseling and vision screenings are valuable in themselves. But de Blasio’s promise of quick academic turnaround has invited questions about Renewal’s effectiveness and whether resources can be more effective in improving low-performing schools than shuttering them.

To assess the program’s academic effect, Pallas compared changes in Renewal school test scores to other schools that had similar test results and student demographics when the program started, but did not receive extra support.

The biggest gains Pallas found were concentrated at the elementary level.

Over the past three school years, 20 elementary schools in the Renewal program have made larger gains on average in math and reading than 23 similar schools that didn’t get extra resources. The proportion of elementary school students considered proficient in reading at Renewal schools increased from 7 percent in 2014 to 18 percent last year — an 11-point jump. Meanwhile, the comparison schools also saw gains, but only by seven percentage points, giving Renewal schools a four percentage point advantage.

At the middle school level, the results are less encouraging. The 45 Renewal middle schools did not collectively outperform a group of 50 similar schools outside the program in reading or math.

In math, for instance, Renewal school students improved from 5 percent proficient to 7 percent. However, the comparison schools outside the program improved by roughly the same margin — increasing proficiency from 6 to 9 percent (and still far below city average). In reading, Renewal middle schools showed slightly less growth than the comparison group.

City officials have argued that Pallas’ findings are misleading partly because Renewal schools and the comparison schools are not actually comparable. Renewal schools, they say, were designated based on a range of factors like school climate or teacher effectiveness, not just student demographics and test scores.

“The schools included in the study are neither similar nor comparable in quality and a comparison of the two dissimilar groups is unreliable at best,” Michael Aciman, an education department spokesman, said in a statement. Aciman added that Renewal schools have made larger gains in reading and math than similar schools across the state, and have made progress in reducing chronic absenteeism and improving instruction.

Pallas notes that there are some limitations to his approach, and acknowledges that he could not account for some differences between the two groups, such as the quality of a school’s principal. He also does not use student-level data, for instance, which would allow a more fine-grained analysis of whether the Renewal program is boosting student achievement. But Pallas, and other researchers who have previously reviewed his data, have said his model is rigorous.

The Manhattan Institute’s Winters found more positive trends than Pallas, consistent with his earlier findings. Using an approach that evaluates whether Renewal schools are outperforming historical trends compared with schools outside the program, Winters found that the Renewal program appeared to have a statistically significant effect on both reading and math scores — roughly equivalent to the difference in student achievement between charter schools and traditional district schools in New York City.

Asked about how to interpret the fact that his results tended to be more positive, Winters said either interpretation is plausible.

“It’s hard to tell which of these is exactly right,” he said. But “neither of us are finding results that are consistent with what we would expect if the program is having a large positive effect.”

Five things to know about the latest brouhaha over Tennessee’s TNReady test

PHOTO: Laura Faith Kebede

Last week’s revelation that nearly 10,000 Tennessee high school tests were scored incorrectly has unleashed a new round of criticism of the standardized test known as TNReady.

Testing company Questar says it muffed some tests this spring after failing to update its scanning software. A year earlier, a series of mistakes got its predecessor, Measurement Inc., fired when Tennessee had to cancel most of TNReady in its first year after a failed transition to online testing.

While the two companies’ glitches are hardly comparable in scope, Questar’s flub has uncorked a tempest of frustration and anger over the standardized assessment and how it’s used to hold teachers accountable.

Here are five things to know about the latest TNReady flap:

1. A relatively small number of students, teachers, and schools are affected.

State officials report that the scoring problem was traced to only high school tests, not for its grade-schoolers. Of the 600,000 high school end-of-course tests, about 9,400 were scored incorrectly. Most of the fixes were so small that fewer than 1,700 tests — or less than one-tenth of 1 percent — saw any change in their overall performance level. A state spokeswoman says the corrected scores have been shared with the 33 impacted districts.

2. But the TNReady brand has taken another huge hit.

Tennessee has sought to rebuild public trust in TNReady under Questar and celebrated a relatively uneventful testing season last spring. But the parade of problems that surfaced during TNReady’s rollout, combined with this year’s drops in student performance under the new test, have made subsequent bumps feel more like sinkholes to educators who already are frustrated with the state’s emphasis on testing. Questar’s scanning problems were also tied to delays in delivering preliminary scores to school systems this spring — another bump that exasperated educators and parents at the end of the school year and led many districts to exclude the data from student report cards.

3. State lawmakers will revisit TNReady — and soon.

House Speaker Beth Harwell asked Monday for a hearing into the latest testing problems, and discussion could happen as early as next week when a legislative study committee is scheduled to meet in Nashville. Meanwhile, one Republican gubernatorial candidate says the state should eliminate student growth scores from teacher evaluations, and a teachers union in Memphis called on Tennessee to invalidate this year’s TNReady results.

4. Still, those talks are unlikely to derail TNReady.

Tennessee is heavily invested in its new assessment as part of its five-year strategic plan for raising student achievement. Changing course now would be a surprise. Last school year was the first time that all students in grades 3-11 took TNReady, a standardized test aligned to the Common Core standards, even though those expectations for what students should learn in math and English language arts have been in Tennessee classrooms since 2012. State officials view TNReady results as key to helping Tennessee reach its goal of ranking in the top half of states on the Nation’s Report Card by 2019.

5. Tennessee isn’t alone in traveling a bumpy testing road.

Questar was criticized this summer for its design of two tests in Missouri. Meanwhile, testing giant Pearson has logged errors and missteps in New York, Virginia, and Mississippi. And in Tennessee and Ohio this spring, the ACT testing company administered the wrong college entrance exam to almost 3,000 juniors from 31 schools. Officials with the Tennessee Department of Education emphasized this week that they expect 100 percent accuracy on scoring TNReady. “We hold our vendor and ourselves to the highest standard of delivery because that is what students, teachers, and families in Tennessee deserve,” said spokeswoman Sara Gast.
