1、RA:

The allowance of American scholarship RA is paid by the professor's research funds. Subsidies are available all year round, and you can attend academic conferences without taking exams.

2、TA:

The allowance comes from the department and is responsible for correcting homework. The allowance is only nine months. During the three months of summer vacation, students need to work at school or outside.

Second, the advantages are different:

1、RA:

RA has a lot of freedom, so it can work around the clock when it is not busy with homework, and can concentrate on preparing for the exam when it is near.

2、TA:

TA because it is a department that gives money, it usually has no money halfway. However, to do TA, the TSE department is generally required. If a certain score is not reached, students may be disqualified from continuing to do TA.

Extended data

RA requires students to participate in the professor's research work, including experimental operation, data analysis, programming and even cooperative papers. The duties of teaching assistants include helping professors manage laboratories and grading test papers.

Often, a graduate teaching assistant (RA or TA can only take one of them) includes tuition fee remission (from semi-exemption to full exemption) and an allowance (ranging from several thousand dollars to tens of thousands of dollars per year).

Most students who get GA can also get additional scholarships, generally not exceeding 10000 USD per year. If you can get tuition-free GA plus grants, the total amount is likely to reach or even exceed the total cost of the school for one year, while the amount of scholarships for graduate students is often not too high, generally not exceeding 1 10,000 US dollars.
