Yes they do... although they are slower to change than Prestige.
They are tied to the average awareness of the players you sign. For anything 4-stars and higher, your average player each year must be an A- or better. To maintain 6 stars you better not recruit more than one or two guys a year who do not have an A+.
If you are already an Academic school, you will have more guys wanting to show up that care about that... Duh... 
If you are not, you will rarely see guys who care about it because they wouldn't be coming to your school in the first place.
If you are playing a typical 3 or 4 star school and you are recruiting pretty much the guys who show up that like your school, you will probably stay at 3 or 4 for a long time. But if you go after a bunch of guys with D+ awareness don't be surprised to see your rating drop.
In addition to being the original Madden Chise guru, I have successfully received the Heisman Trophy in NCAA 2005 at EVERY single position, including K, P, FS, SS and all five OL positions... Man did I have a lot of free time the last eight months... (DuckFan circa July 2005)
For what it's worth I never got the Heisman with a FS or RG with 2006, though I did get it with all the other positions...
