Being a teaching assistant (TA) as an undergraduate math major can provide valuable experience, even if the work primarily involves grading tests and homework. While some argue that graduate schools prioritize grades and letters of recommendation over TA experience, there are several benefits to consider. Serving as a TA can enhance understanding of foundational concepts, which may be beneficial for graduate-level exams. It also offers a glimpse into teaching, a skill that can be crucial for an academic career. Although grading may seem tedious, it can help develop a conscientious approach to student learning and misconceptions. Engaging with students through tutoring or recitation can be more rewarding and instructive than grading alone. Ultimately, while TA experience may not be essential for graduate school admission, it can enrich a resume and provide insights into teaching and learning processes.
