Difference Between Instructor and Professor

Key Differences

An instructor typically refers to someone who teaches or imparts skills or knowledge. Their role is primarily focused on the act of teaching, whether it's in schools, workshops, or training sessions. A professor, on the other hand, holds an official academic title at a college or university, often indicating a certain rank and a blend of teaching, research, and administrative responsibilities.
Within the academic hierarchy, an instructor might not have the same standing as a professor. The instructor role often doesn't require the same level of advanced degrees or credentials that a professor position would. Professors usually have a doctorate in their field and might have progressed through academic ranks, such as assistant or associate professor, to reach their status.
In terms of roles, an instructor could exist in various educational environments, like community colleges, trade schools, or non-academic settings. They provide hands-on training or classroom instruction. A professor, while also teaching, usually has added duties like publishing research, mentoring students, serving on committees, and contributing to their academic field.
In everyday language, the word instructor might be used more generically for anyone who provides instruction, like a gym instructor or a flight instructor. A professor specifically references someone in an academic setting, with students often using the title as a form of respect.
