Teaching assistant

A teaching assistant (TA) is an individual who assists a professor or teacher with instructional responsibilities. TAs include graduate teaching assistants (GTAs), who are graduate students; undergraduate teaching assistants (UTAs), who are undergraduate students; secondary school TAs, who are either high school students or adults; and elementary school TAs, who are adults (also known as paraprofessional educators or teacher's aides). By definition, TAs assist with classes, but many graduate students serve as the sole instructor for one or more classes each semester as a teaching fellow or graduate student instructor, although in some American states, such as Florida, they are called "teaching assistants". Graduate and adult TAs generally have a fixed salary determined by each contract period (usually a semester or an academic year); however, undergraduates and high school students are sometimes unpaid and in the US and other countries with the credit system, receive course credits in return for their assistance.
