Necessary but not sufficient: My aerospace engineering degree is from an ABET-certified school. However, I skipped the class (and test) that puts you onto the track of being able to call yourself a professional engineer.

I would also suggest looking at the ABET certification interval for different campuses. It was a point of pride on our campus that we had a longer interval compared to the more established campus. We got the longer interval because ABET trusted our program to not need constant supervision.
