Archaeology

Bachelor's degrees are generally required for entry-level archaeology positions, such as field assistant, surveyor or museum technician. Aspiring archaeologists typically pursue degrees in anthropology, which consist of studies in archaeology, cultural anthropology, biological anthropology and linguistics
Graduates in history in any stream with an aggregate of 55% marks can apply for Diploma, postgraduate Diploma or post graduation (MA/ M.Sc) in different fields of archaeology. Duration of these courses may vary from 1 year to 2-years. Admission to the two-year post graduate Diploma course at the Institute of Archaeology, the academic wing of the Archeological Survey of India in New Delhi, is on the basis of a written exam and an interview.
At a higher level, those interested in conducting research on the various branches of Archaeology can do Ph.D. But before applying for the research fellowship, they must have completed their post graduation.
