More on growth-only grading of schools

Hats off to the folks at the Indiana Coalition for Public Education-Monroe County for keeping a spotlight on the unfairness of Indiana’s A-to-F school grading system.

It’s unfair that schools in their first three years of operation are evaluated on test-score growth only, while other schools are graded on a mixture of growth and performance – the percentage of students who pass state tests. Those new schools are disproportionately charter schools, private schools or Indianapolis Public School “innovation” schools. The result is, their grades are inflated.

In response, the coalition’s Keri Miksza and Jenny Robinson have calculated the grades that public schools would receive if they were graded on growth only. They’ve been posting the results to Facebook and Twitter, using a format from a Washington Township (Indianapolis) parent council. A few examples:

  • Monroe County Community Schools – Using growth, 15 schools would get A’s, one would get a B and one a C. Under the actual grading system, there were about as many B’s and C’s as A’s.
  • Lawrence County — 10 schools would get A’s, four would get B’s and two would get D’s. Under the actual system, only one school got an A and most got C’s and D’s.
  • Owen County — four schools would get A’s and one would get a B. In fact, all got B’s, C’s and D’s.

Even in much-derided Indianapolis Public Schools, a majority of schools would get A’s and B’s if graded only on growth. Using the existing grading system, nearly all get C’s, D’s and F’s. Results are similar for South Bend schools.
