I have a report card form that I'm creating for customers to rate performance in several areas. Our old format was using radio buttons, each labeled A-F with one N/A option. The current idea from marketing is to just have users input the letter grade in a text field.
I'm thinking that there's a more simple intuitive way to present this kind of data, but I'm having trouble finding any ideas. Perhaps I'm searching for the wrong thing. I was considering using a fixed unit slider and displaying the letter grade next to it. I don't think that management would be too keen on changing the rating unit either (no 5 stars or anything). Any great methods out there?
