What qualifications are necessary for teaching assistant jobs?

The qualifications that are necessary to be a graduate teaching assistant are usually a high GPA and college-level knowledge of the subject one is applying to teach. Admission into the program you are applying to teach and prior teaching experience is also desirable. If you don't have any teaching experience, think about any jobs you have had with transferrable skills that could be applied to teaching: tutors, mentors, child care experience.
