If we’re going to grade schools on performance, “shouldn’t we measure them all with the same yardstick?”

Currently “schools in their first three years of operation—most of which are new charter schools. . . can have their grades calculated on growth only, with no consideration of performance.” 

Using the current guidelines “about 80 percent of Indiana schools would get A’s [if graded on growth].  Conversely, if schools were graded on performance alone, about 2 percent would get A’s.”
