I didn't officially graduate from Worcester Polytechnic Institute until years later when I was awarded their honorary Ph.D.

A factual statement is an objective statement that cannot be disputed because the evidence is available.

By saying that they did not officially graduate from the Institute until they got their Ph.D, the speaker is making a statement of fact.

This stems from the fact that to officially graduate from an institution of higher learning, one has to be awarded the qualification they were studying for and so in getting the honorary degree, the speaker had officially graduated.
