A Student Assistant is a position for a student enrolled at university and entails assisting faculty members, basically in everything they do not want to do themselves. This includes a wide variety of tasks, from handling administrative tasks related to the academic matters of students to proofreading academic papers, sourcing references, or doing research for lecture preparation.
There are part-time student assistant positions available on most college campuses. Most of the job is done either at campus offices, responding to student inquiries, handling admission forms, or maintaining student files or at the library doing the legwork for academic research, collecting and organizing data.
However, you need to have great interpersonal skills as well because student assistants contribute to organizing community life on the campus, helping students not only with administrative problems but occasionally providing counseling for personal matters, too.
