When Colorado officials released a trove of test results last week, it showed the continuation of a sobering trend line: historically underserved students are lagging behind other students, and the gaps are not closing.

This is due in part, they said, to all students doing slightly better during the last three years on the state’s English and math test.

In the graphics below, we take a closer look at how those gaps are playing out across the state. That includes a look at how students of different racial and ethnic backgrounds scored on the SAT, which for the first time high school juniors across the state were required to take.

How achievement gaps on the PARCC tests changed in 2017

Looking at a sample of tests, you can see how racial and ethnic groups grew between 2016 and 2017. When most groups raise test scores, it does little to cut into achievement gaps.

A baseline for the SAT

Last spring, Colorado juniors were required to take the SAT. Previously, juniors took the ACT. This graph represents how different racial and ethnic populations scored on the inaugural exam. Asian, white and biracial students all outperformed their black, Hispanic and Native American peers.

Where students are growing the most

One way the state can close the achievement gap is by accelerating the learning of at-risk students. The state tracks this by measuring student growth.

Growth is measured by comparing how much students learn each year compared to students who have a similar score history on standardized tests. If a group of students hits the 50th percentile, that means they’ve learned about a year’s worth of material. The higher the percentile over 50, the more and faster students are learning.

These graphics show where historically underserved students are learning the most and the quickest based on the state’s student growth measurement. Noticeably missing from many of these graphics are the state’s largest school districts. That said, just because you’re small doesn’t mean growth comes easier. Several small districts also posted some of the worst growth scores in the state, as well.

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.
