CLEP exam 20 year limit

[clep3705]

Consider this scenario.

1. You passed a CLEP in 1996.
2. It's now 2017.
3. Your CLEP pass is gone.

Now consider this:

1. You passed a CLEP in 1996.
2. You passed a CLEP in 2015.
3. It's now 2017.
4. Will your 1996 CLEP still show up on your transcript? Or only your 2015 CLEP?

Is the 20 years about keeping your records in an active status or is the 20 years is about your pass still being considered current and valid?
