Ph.D. degree, and each college or department within a university sets specific standards by which it measures
mastery of a subject. Because examinations given as part of a Ph.D. curriculum assess expert knowledge, they
are created and evaluated by a committee of experts, each of whom holds a Ph.D. The essence of a Ph.D., the aspect that distinguishes Ph.D. study from other academic work, can be

dissertation to the faculty and defend their work an oral examination.
