High stakes failure

It might be becoming apparent to any rational observer that high stakes corporate education policies are failing catastrophically. Where once various data and tests were used to inform educators and provide diagnostic feedback, they are increasingly being used to rank, grade, and even punish.

This is leading to the inevitable behaviors that are always present when such systems are created - whether it was in the world of energy companies such as Enron, or other accounting scandals including those affecting Tyco International, Adelphia, Peregrine Systems and WorldCom, to the more recent scandals involving Lehman Brothers, JPM or Barclays bank.

Here's another example, in news from Pennsylvania

After authorities imposed unprecedented security measures on the 2012 statewide exams, test scores tumbled across Pennsylvania, The Inquirer has learned.

At some schools, Pennsylvania Secretary of Education Ronald Tomalis said, the drops are "noticeable" - 25 percent or more.

In some school systems, investigators have found evidence of outright doctoring of previous years' tests - and systemic fraud that took place across multiple grades and subjects.

In Philadelphia and elsewhere, some educators have already confessed to cheating, and investigators have found violations ranging from "overcoaching" to pausing a test to reteach material covered in the exam, according to people familiar with the investigations.

When trillions of dollars of the world's money is at stake, investing in tight oversight and regulation is imperative, but when it comes to evaluating the progress of a 3rd grader, do we really want to spend valuable education dollars measuring the measurers?

The question becomes even more pertinent when one considers that the the efficacy of many of the measures is questionable at best. Article after article, study after study, places significant questions at the feet of value add proponents, and now a new study even places questions at the feet of the tests themselves

Now, in studies that threaten to shake the foundation of high-stakes test-based accountability, Mr. Stroup and two other researchers said they believe they have found the reason: a glitch embedded in the DNA of the state exams that, as a result of a statistical method used to assemble them, suggests they are virtually useless at measuring the effects of classroom instruction.

Pearson, which has a five-year, $468 million contract to create the state’s tests through 2015, uses “item response theory” to devise standardized exams, as other testing companies do. Using I.R.T., developers select questions based on a model that correlates students’ ability with the probability that they will get a question right.

That produces a test that Mr. Stroup said is more sensitive to how it ranks students than to measuring what they have learned. That design flaw also explains why Richardson students’ scores on the previous year’s TAKS test were a better predictor of performance on the next year’s TAKS test than the benchmark exams were, he said. The benchmark exams were developed by the district, the TAKS by the testing company.

We have built a high stakes system on questionable tests, measured using questionable statistical models, subject to gaming and cheating, and further goosed by the scrubbing of other student data. We've seen widespread evidence of it in New York, California, Washington DC, Georgia, Tennessee, Pennsylvania, and now Ohio.

Policymakers are either going to have to spend more and more money developing better tests, better models, tighter security and more bureaucratic data handling policies, or return to thinking about the core mission of providing a quality education to all students. Either way, when you have reached the point where the State Superintendent talks of criminalizing the corporate education system, things have obviously gone seriously awry.

State Superintendent Stan Heffner, who leads the department, has launched his own investigation and has said the probe could lead to criminal charges against educators who committed fraud.

More cheating exposed

No sooner had we pegged cheating scandals as our number 4 story of the year, than a new scandal emerges, this time in Georgia.

A new investigative report details a second major standardized test cheating scandal in a Georgia school system, implicating 49 educators, including 11 principals. A key reason for the “disgraceful” cheating, investigators said, was pressure to meet No Child Left Behind requirements.

The probe (see here and here) by the Georgia governor’s Special Investigators team into cheating in the Dougherty County School System concluded that “hundreds of school children were harmed by extensive cheating.”

“While we did not find that Superintendent Sally Whatley or her senior staff knew that crimes or other misconduct were occurring, they should have known and were ultimately responsible for accurately testing and assessing students in this system. In that duty, they failed,” the 293-page report says.

Wherever we have corporate education reforms we find unsavory corporate behaviors.

High stakes testing leads to cheating

It has been well documented that Washington DC schools, while being led by Michele Rhee engaged in widespread cheating of tests in order to artificially boost performances. Now a second large school district that employed high stakes testing to drive high stakes decisions has been found to have engaged in widespread cheating. This time in Atlanta Public Schools

State investigators have uncovered a decade of systemic cheating in the Atlanta Public Schools and conclude that Superintendent Beverly Hall knew or should have known about it, The Atlanta Journal-Constitution has learned.

In a report that Gov. Nathan Deal planned to release today, the investigators name nearly 180 educators, including more than three dozen principals, as participants in cheating on state curriculum tests, officials said over the weekend. The investigators obtained scores of confessions.

Cheating was uncovered in 44 of 56 schools investigated involving 38 principals and 178 teachers - 82 of whom confessed to misconduct. The 2 page report, below, states:

Cheating was caused by a number of factors but primarily by the pressure to meet targets in the data-driven environment

Summary of APS cheating scandal

That same pressure will now exist in every school in Ohio as teachers pay and careers will be measured in large part by their students test results - tests that have proven to be unreliable for such uses.
