I like what my D’s school does for most of their scholarships. If you don’t meet the 3.0 cumulative GPA threshold at the end of freshman year or subsequent, you’re put on scholarship probation. You then have to get a 3.0 in every semester during which you’re on probation to avoid losing the scholarship. Once you pull the cumulative GPA up to 3.0, then you’re off scholarship probation. However, even if you never pull it up to 3.0 (for instance after one of those catastrophic freshman years), as long as you get a 3.0 every semester after that, you’re good. It can make for some stressful semesters, especially for students in fields, such as engineering, where a 3.0 isn’t all that easy to achieve, but it seems more than fair to me. And the scholarship stays in place while you’re on probation.
