Your understanding is correct for the US. ‘Faculty’ is most often used to described the staff, usually the teaching and administrative staff. In some cases it could be used to differentiate from other employees. For example: ‘He’s on the faculty’ would suggest that he has an academic job. ‘Faculty’ is not used to describe a department (or ‘college’ or ‘school’) in general American English but might still exist as part of the technical vocabulary within a university.

In British universities, faculties are departments, not staff. I've never heard of faculty referring to staff. But if you say "head of faculty" that can be a staff member, ie, the head of a department.

Here in England we also use faculty to describe a division within a university comprising one subject area. Faculty of English, Faculty of Medicines, Faculty of Social Studies etc.

Hello! You’re absolutely right about the confusion—this is common in many non-English-speaking countries, where "faculty" can mean a department or section within a university. In English-speaking countries, however, faculty typically refers to the academic staff as a whole (professors, lecturers, and researchers). To describe a specific section within a university (e.g., the part dedicated to a certain field, like Engineering or Humanities), native English speakers usually say "department" or "school" (as in "Department of Biology" or "School of Law"). In short, it’s better to avoid using "faculty" to describe a section or division within the university when speaking English, as it could lead to misunderstanding. Instead, sticking with "department" or "school" will make it clearer. Hope this helps, and good luck with your studies!

Both uses are accepted in the U.S. What is "calque"?
