Ph.D.

A Doctoral, Doctorate in Philosophy, or for short, Ph.D. is the most advanced degree available in most fields of study. It is qualitatively different from most of the "junior" degrees. Completing a doctorate usually involves some sort of "original contribution" to the field. The kinds of work that count as an original contribution will vary by field: a theory, experimental results, a creative work. Some masters programs require similar original work, but generally not to the same extent.
