The afternoon is only half over, but the sun is riding a little low in the sky. Within a few hours, it's going to get dark outside. That's because we switched the clocks last night.
Here's the thing-- it will get precisely as dark as it got yesterday, just as the sun rose just as high today as it rises every single day. The distribution of light and dark through the day, the distribution of the sun's high points and low points-- it will be pretty much the same today as it was yesterday.
What changed over night is not the distribution of light and dark, but the labels that we put on it. Yesterday we labeled this position of the sun 4:00. Today we are labeling it 3:00.
For those who don't get it, this is a fine way to explain cut scores. The distribution of student scores, the lights and darks, the highs and lows-- that stays pretty much the same. What changes is how people chose to label them. We can take the highest point of the curve and we can call it "on level" or "above expectations" or "below expectations." And the labels we use are reality-- it's not true to say that right now it is "really" 4:00. It's 3:00, today.
The position of the sun, just like the number of students who got a certain number of questions correct on a test-- that's a piece of raw data. But what we label it, whether we label it 12:30 AM or "Exceeds expectations," is just a label, even an arbitrary label, that we have slapped on the raw data to give it meaning. And we can give it any meaning we want.
Many folks make fun of daylight savings time because it doesn't really change a thing. Sun is still up for the same number of hours, and we stumble around in the dark for the same number of hours. Nothing really changes except the label we install. If I have the authority, I can make this moment 3:00 or 4:00 or 9:00 or 13:00. It won't change the reality of the moment-- just what we call it. Standardized test results, predictably draped across the bell curve, are the same. If I have the authority, I can label the parts of the curve anything I like. But it won't change reality a bit.
Your point is well taken. But my psyche feels better when I don't leave for work in the dark. And that is the terrible thing about cut scores. We label children as failures and destroy their souls--when they are not.
