Information on Staff
A character can take classes or have a job outside of the school while still being staff. A staff character taking some classes is not considered a student. However, a full time student can get a job at the school, although they'd be classed as a student first and foremost.
For example, a teacher could take classes outside their own area of expertise for academic curiosity, but could not get a degree for doing so. They would be considered staff. Similarly, a student could work as a teacher's assistant, but they'd be considered a student.
Staff in Starlight Academy are closely monitored and expected to be professional. Not to say your staff member can’t do bad things, but if they do, there’ll be repercussions if what they did is ever released to public knowledge.
If there isn’t a specific staff member on the list, always assume there are NPCs taking on their work. Starlight Academy is never short on staff.
