"In addition to an academic grade, the 950 students at the school will get a separate “life skills” grade for each class that reflects their work habits and other, more subjective, measures like attitude, effort and citizenship."

So why not have a comments section? Is it too much to ask that a subjective assessment be spelled out in a written sentence or two?
The problem is that, in our increasingly data driven world, comments are very hard to deal with on the large scale. I'm actually working on trying to define goodness around teaching interactions, and one of the big wildcards is how we structure feedback such that we get the depth of comments, and the processability of numbers. It's tough.
I don't see any indication that there is not a comments section.
