No, the State Eligibility Test (SET) is not typically the primary entrance exam for PhD programs. SET primarily assesses eligibility for lectureship positions and Junior Research Fellowships (JRF) in Indian universities and colleges. PhD admissions typically require candidates to clear exams like the CSIR-UGC NET, GATE, or university-specific entrance tests, depending on the field of study and institution. While some universities may consider SET scores for PhD admissions, it's less common compared to exams specifically designed for doctoral research eligibility. Prospective PhD applicants should verify the specific entrance exam requirements of the universities and programs they are interested in to ensure they meet all necessary criteria.
