Like nearly all schools across the state, Indianapolis Public Schools saw ISTEP scores take a steep drop in 2015, but at the schools at the lowest rung of the district’s results the scores were especially bleak.

Among the state’s lowest scoring schools are six from IPS that saw the percentage of students who passed both the math and English sections of ISTEP drop to the single digits.

Last year just three schools in the state scored that poorly.

Indiana knew there would be a dramatic dip in ISTEP scores in 2015, following the introduction of new standards in 2014 and a more difficult test to match. For IPS, the district-wide passing rate fell 22 percentage points, which mirrored exactly the decline across the state. But many IPS schools already were among the worst performing in Indiana — in both 2014 and 2015 only four other Indiana school districts had lower passing rates on ISTEP.

Superintendent Lewis Ferebee said he didn’t put much stock in looking solely at ISTEP scores as a measure of success. He said the district’s staff will look closely at the schools that saw the greatest drops in scores and at those with long records of poor performance but wouldn’t dwell on the state test’s grim verdict.

“We don’t really think these results are reflective of the work of our students and staff,” he said.

Within IPS, there was wide variation in ISTEP scores among schools.

Four of the state’s 20 lowest scoring schools were in the district, but it also has the top performing public school. At Merle Sidener Gifted Academy, a selective magnet school, 95.5 percent of students passed the test.

That’s more than 30 times the passing rate for middle school students at John Marshall High School, where just 3 percent passed. In other words, about 10 students out of the 340 middle school students at Marshall passed ISTEP.

Marshall has the lowest pass rate in IPS, but it still faired better than seven other schools in the state. The middle school scores at Marshall have been the worst in the district for three years running. In 2014, 15 percent of Marshall students passed ISTEP. That number fell by 12 percentage points in 2015.

There were surprises at a few schools in the district, where scores dropped dramatically. For example, at School 56, a magnet Montessori school, the passing percentage sank by 55 percentage points — the worst drop in the state. In 2014, School 56 was one of the top 10 schools in IPS, winning accolades for a big turnaround from low scores in the past.

The second biggest drop in IPS was at Cold Spring School, another magnet school and one with a record of strong performance on tests. Passing rates at the school declined by 48 percentage points, and just 28 percent of students passed in 2015. Cold Spring is looking to convert to an innovation school, which would have significantly more independence from the district.

Even so, IPS had some success stories. School 107, for example, was in very exclusive company. It was one of just four schools in the state that actually saw its ISTEP passing percentage improve. The school saw a big dip in scores in 2014, so the improvement was something of a rebound.

IPS declined repeated requests to interview school principals or district administrators about the results. Ferebee answered questions after attending a summit meeting with Mayor Joe Hogsett this morning after IPS said nobody was available to discuss ISTEP.

Schools that have repeatedly struggled with low scores have already been targeted for changes, Ferebee said. For example, four of the schools where fewer than 10 percent of students passed the test are combined middle and high schools like Marshall.

Middle school students also had some of the lowest test scores in IPS in 2014, and the IPS board has pledged to remove middle school students from high schools as a way of improving test scores.

The other two schools with the lowest passing rates in IPS also have long records of poor test scores. School 103, which received failing grades from the state for four years running, was converted into the district’s first innovation school this year. The school is now run by the Phalen Leadership Academy charter school network under a contract with IPS.

The other elementary school with a single-digit pass rate is School 44, a long-struggling school. District leaders will decide whether to make changes at School 44 and other persistently low-scoring schools in the coming weeks, Ferebee said.

“We wouldn’t use this one snapshot in time to determine whether or not we’re making progress or which schools are struggling,” he said. “(But) we continue to be worried about particularly our schools that have been historically low performing.”

The 2015 ISTEP has been plagued by problems and controversy, most recently the revelation from the Indianapolis Star that thousands of tests may have been misscored due to a computer malfunction.

Test scores are typically tied to several accountability measures, from teacher pay to school letter grades. But a senate bill that would suspend those repercussions for the most recent test is winning bipartisan support.
