There have been a few discussions lately about grades and grading, but they have been more political and less functional. I'd enjoy the opportunity for a functional discussion here.
If you're going to participate, all I ask is that you don't be a jerk or make this into some dogmatic hill to die on. And try not to be negative; I'm legitimately worried about a few of you.
For a history of grading in the US, this is a short read with links to deeper dives.
Currently, most elementary and secondary grading systems in the US appear as some variation of a leptokurtic distribution with a negative skew:
A: 94%-100% accuracy on assignments and assessments (Highest merit)
B: 85%-93% accuracy on assignments and assessments (With merit)
C: 76%-84% accuracy on assignments and assessments (Average/Mean achievement)
D: 69%-75% accuracy on assignments and assessments (Poor/below mean achievement)
F: 0%-68% accuracy on assignments and assessments (No achievement of merit)
A grade in the C range was designed to be the center of the bell curve, with the most students landing in this category of mastery. A grade of B was considered to show solid and consistent achievement on assignments and a grade of A showing near flawless completion of all assessments and assignments. Grades of D and F were supposed to be warning signs that prompted increased intervention by the teacher.
The biggest problems come from the fact that grades in this manner tend to represent completion, not mastery. For example, my junior year of High School I received a grade of D in first semester honors english while also receiving a 36/36 in Reading Comprehension and a 35/36 in Language Arts on the ACT. My grade in no way reflected my mastery of the skills, just that I thought my homework was a waste of time and the books we were supposed to read were boring. I had As and Bs in all my other classes. But, I digress.
One of the things that I heard frequently as a middle school teacher and now as a parent of school-age children is "I want an A for my child! Why can't my child get straight As! It's the teacher's fault for not teaching well enough!" That's actually not the case at all; again, back to the leptokurtic distribution with negative skew. If the goal is an increase in accuracy on assignments and assessments, then the plot will need to change to reflect that again. It will become even more leptokurtic and skew even further in the negative. As a C will remain the center of the frequency chart, a grading scale that represents higher achievement would need to look like this:
A: 97%-100% accuracy on assignments and assessments (Highest merit)
B: 92%-96% accuracy on assignments and assessments (With merit)
C: 86%-91% accuracy on assignments and assessments (Average/Mean achievement)
D: 79%-85% accuracy on assignments and assessments (Poor/below mean achievement)
F: 0%-78% accuracy on assignments and assessments (No achievement of merit)
While this raises the accuracy on completed assignments and assessments, it does nothing to address the desire for the highest possible grades and starts to appear as if grade inflation is taking place. An A becomes even harder to achieve, while D and F become even easier. Again: this isn't about mastery, but about completion and accuracy. You can't look at either example grading scale and ascertain if your child got a C in maths because they are having trouble with fractions or a D in Language Arts because they have issues with visual processing of language (but would have an A if it were read to them).
So my question to the group here is this: should we be focusing on tightening the current scoring system, or should we examine ways to connect completion/accuracy to mastery and have grades that paint a more full picture of what our children are capable of?
