Assistantships Every year, MIT Sloan appoints a number of MBA students to teaching and research assistantships that vary in workload and stipend percentage. While helping students cover their expenses, these competitive positions offer outstanding exposure to the school's educational and research programs. Responsibilities may include working one-on-one with students, assisting in research, and grading assignments and examinations. TA and RA positions are available each year to MBA students beginning in the second semester, as well as PhD students. Please note that students who initially receive loans and later receive additional support (TA, RA, fellowship, etc.) may have their total loan package reduced. MIT Student Financial Services will guide you in these situations.
