GPA to maintain scholarship was a consideration for us too. D’s scholarship requires a 3.25 and she’s in engineering. We weren’t too concerned going in, knowing that she was capable, sensible, and had good study habits already. But we still discussed it. The transition to college can be a challenge. She had a ton of AP credit so she stepped straight to some more advanced classes but also was able to have a lighter load at first. We didn’t push her to find a job first semester.
We also discussed a backup plan for if she lost the scholarship–come back, live at home, and finish the degree at local state U (If she had not been a top student and earned scholarships this would have been plan A).
After year one, there’s no indication we are going to ever need that plan B. 
I think it’s reasonable to ask the school’s how the students who are awarded the scholarships you are offered do at keeping the award through graduation. They may or may not say, but how they respond may gain you some helpful information.
