It’s almost mid-October, but Indiana still has not publicly released state ISTEP test scores or A-F accountability grades for schools.

If it seems like they used to come out a lot earlier, that’s because they did.

In the first six years after the state tests moved in 2009 to being administered in the spring — rather than the fall — ISTEP scores were never publicly released later than mid-September. In three of those years, the scores came out in June or July.

The story is similar with A-F grades. In 2011, the first year Indiana began assigning grades to schools, they came out in August. They haven’t come out earlier than the end of October since.

The slow release of test scores has even become an issue in the race for governor. Both Republican Eric Holcomb, the state’s lieutenant governor, and Democrat John Gregg, a former Indiana House speaker have called for the test to be scored more quickly so that teachers can actually use the results to make adjustments to their teaching.

So why are scores and grades so slow to come out these days? And is there any hope the state could get them out earlier? Not with the current process, state Superintendent Glenda Ritz said last week.

There are three big reasons why:

Results today require more verification

Test scores today go through a more rigorous vetting process than they did in the past.

“There is an entire process we must go through,” Ritz said.

For one thing, parents are much more active than they were just a few years ago in asking for a student’s test be re-scored. In fact, some schools encourage parents of students who fell just short of a passing score on ISTEP to request a re-score in hopes it will boost the student’s score and help the school improve its passing percentage.

This also will be the second year for an overhauled and expanded ISTEP, changes that were required to match the test to new, more rigorous state academic standards that were put in place in 2014. After big test changes, more checking is required to assure the new exam is producing accurate results, Ritz said.

One more big change is Indiana‘s switch to a new test company.

After several years of scoring problems and delays, frustrated state officials backed out of Indiana’s long relationship with CTB, formerly CTB-McGraw Hill, picking its competitor, Pearson, to create and score ISTEP instead. Ritz said it is routine to have extra scrutiny after changing companies.

“We’ve had several changes in the assessment that required us to have a delay in when all the scores come out due to changes in the actual test itself,” she said.

Getting test scores back to teachers is top priority

Ritz proudly pointed out that teachers and schools received student test scores shortly after the start of the new school year.

“They have all the student data,” she said. “Teachers already working on what they need to do with instruction. I feel really good about that. That was our priority this year.”

Parents have also been able to access their children’s test scores through an online system since early September.

Pushing to get test results to teachers and parents faster means making the public release a lower priority.

In a word: politics

Changes in state law now require Ritz’s team to deliver state aggregate ISTEP results to the Indiana State Board of Education by July 1, Ritz said. So that has become the first ISTEP task, followed by the push to get the scores ready for teachers and parents.

But for the public release of the scores, followed by A-F school accountability grades, the state goes more slowly to ensure these high-stakes results are accurate. Test results and grades can affect teacher evaluations, even preventing pay raises for those whose students don’t make gains. They can even lead to interventions like state takeovers for schools that repeatedly post low scores.

In recent years, state board members and legislative leaders have even asked the Legislative Service Agency, the Indiana legislature’s research arm, to double-check A-F calculations after the education department’s work on them is finished.

So the public release of test scores and grades now comes after the data is delivered to the state board, after the preliminary test scores are delivered to teachers and parents, after parent re-score requests are complete and after all ISTEP scores and A-F grades are verified.

“What we are doing now is the state’s work to move toward the calculation of grades,” Ritz said. “When you get to the high stakes that are attached to our grades here in Indiana, you have to cross your T’s and dot your I’s.”

Her best guess was that scores and grades could be ready by the end of October.
