Graduate applicants are assessed based on academic performance, relevant work experience, research interests, and the alignment of their goals with the program's offerings. In addition to submitting transcripts, letters of recommendation, and a statement of purpose, some programs require standardized test scores like the GRE or GMAT. Admission to graduate programs also depends on the availability of faculty members to supervise prospective students.
