* Faculty refers to the entire body of teachers in a school, college, or university. It's a collective noun. It also implies a higher level of seniority and often academic rank (professor, associate professor, assistant professor, etc.). Faculty members typically have advanced degrees (Masters or Doctorate) and may engage in research, publication, and departmental governance beyond teaching.
* Instructor is a more specific term referring to a teacher, usually at a college or university, but sometimes at other institutions like vocational schools. Instructors may or may not have advanced degrees, and their primary role is teaching. They might have less involvement in research or departmental administration compared to faculty with higher ranks. An instructor could be a member of the faculty, but not all members of the faculty are instructors (some might be administrators, researchers, etc.).
In short: All instructors are part of the faculty, but not all faculty members are instructors. "Faculty" is the broader term encompassing all teaching and related academic staff, while "instructor" designates a specific teaching role within that broader group.
