Guest: Common Core offers promising alternative to letter grades

As we adapt to the Common Core, our traditional grading system of A-F is on the chopping block, and rightfully so. This system, grading on a curve, has tended to perpetuate the status quo.

Because of socioeconomic factors, students with access to fewer educational resources have made lower grades, and students with greater access to educational resources have made higher grades. There are numerous exceptions, but this method has not championed equal opportunity and upward mobility — at least not in accordance with the American dream we tout.

A bell curve on a graph describes random variations in naturally occurring outcomes. But education is not a random undertaking, so critics have rightfully begun to question whether a grading curve is appropriate. In other intentional efforts — such as building a bridge or removing an appendix — we do not expect or tolerate a bell curve. If a bridge collapses into a river, or a patient dies from surgery, we do not chalk it up to a bell curve. Rather, we examine the situation to determine what went wrong and how we can prevent future calamities.
