Professor ("Full Professor", i.e., the destination of the "tenure track," upon exhausting all promotions other than those of special distinction)

In the U.S., the word "professor" informally refers collectively to the academic ranks of assistant professor, associate professor, or professor.

In the United States, the term academic is approximately synonymous with that of the job title professor although in recent decades a growing number of institutions include librarians in the category of "academic staff".
