For softball, there is a national ranking at the D-II level and so, I would think it is the same for all sports. I know that ranking changes a lot due to various things like record, strength of schedule, ... For softball, there is a tournament, usually held in Arizona where the top teams from the country show up and get after it. My daughter and her team played in that two different years. Her senior year they didn't lose a game and she was 1st Team All Tournament.
