No comparing school grades to previous years

Indiana school grades for 2015-16 were released this week, marking the first time the state has used a new grading system designed to count test-score growth as much as performance.

First, let’s note that comparing the new grades to grades from the previous year is meaningless. For one thing, we’re using a new system: It’s supposed to produce different results. Comparing the newly released grades to the previous year’s grades is comparing apples to oranges.

But more to the point, the previous year’s grades were largely bogus. They would have been a lot worse, but lawmakers passed “hold-harmless” legislation that said no school could get a lower grade in 2014-15 than it did in 2013-14.

Remember that Indiana adopted new, more rigorous academic standards in 2014-15, so the ISTEP exams got a lot tougher. Before the hold-harmless legislation passed, state officials said more than half of all schools could receive D’s or F’s. The Indiana Department of Education refused to make public the grades that schools actually would have received last year, even though the state public access counselor said it should.

So if you see that a certain school’s grade dropped from an A to a B this year … well, technically that may be correct. But there’s a good chance the school earned a D or F in 2014-15 but had its grade boosted by the legislature. Continue reading

Board faces weighty decision on rewarding test-score growth

Like it or not, the Indiana State Board of Education will be picking winners and losers in the A-to-F grades sweepstakes when it adopts a table early next year for awarding points for student test-score growth.

Under a new accountability system that the board adopted early this year, growth is supposed to count the same as performance – the percentage of students who pass the tests – in calculating school grades. And growth points will be awarded according to where students fall on a Growth to Proficiency Table.

The question for the board is what that table will look like. Will it award more growth points to students who passed the tests the previous year than to those who didn’t? Or will it award the same points to high-scoring and low-scoring students who show comparable growth on the current year’s tests?

According to discussion at last week’s state board meeting, staff from the board and the Indiana Department of Education will present up to four tables for members to consider in January. The board will give preliminary approval to the option it favors, touching off a 30-day public comment period.

Department of Education staff will then let local school officials know how their schools are likely to be affected. And when the comment period ends, the board will adopt the table of its choice at its next meeting, probably in March or April 2016.

Change coming for Indiana school grades

A change is coming next year to Indiana’s A-to-F school grading system, and it may be a bigger change than even the most education-attuned Hoosiers yet realize.

While the State Board of Education has approved the framework for the new system, it still needs to decide how to award points for student growth on test scores, a key component for calculating grades. That won’t happen until this fall.

And what it decides will matter, according to simulations of what grades would have been if the new system had been in place a year ago. Under one approach to measuring growth, 40 percent of schools would have received As. Under another, barely 20 percent. Either way, it’s a change from the current system, which awarded As to 54 percent of schools last year.

Up to now, elementary and middle schools have been graded largely on the percentage of students who passed ISTEP+ exams in math and reading. They could gain or lose points for student growth on test scores, but performance was the primary factor. And that meant affluent schools typically got As or Bs.

Growth was measured by the Indiana Growth Model, a complex formula in which each student’s test-score improvement was compared with that of all students who scored the same the previous year.

The grading system for high schools is and will remain more complicated. It includes graduation rates and “college and career readiness” measures as well as test-score performance and growth.

The new system for elementary and middle schools will rely on student test-score performance for 50 percent of each school’s score and growth for the other 50 percent. That suggests a more level playing field for high-poverty schools. They may be able to get good grades if students grow enough.

And growth will be based on a “growth to proficiency table,” a new method for awarding points for how much students improved their test performance. Here’s how it will work.
