Doctorates. These are often further divided into academic and professional doctorates. An academic doctorate can be awarded as a Doctor of Philosophy degree (from Latin "Doctor philosophiæ"; Ph.D. or D.Phil.) or as a Doctor of Science degree (from Latin "Doctor scientiæ"; D.Sc.). The Doctor of Science degree can also be awarded in specific fields, such as a Doctor of Science in Mathematics degree (from Latin "Doctor scientiarum mathematic arum"; D.Sc.Math.), a Doctor of Agricultural Science degree (from Latin "Doctor scientiarum agrariarum"; D.Sc.Agr.), a Doctor of Business Administration degree (D.B.A.), etc. In some parts of Europe, doctorates are divided into the Doctor of Philosophy degree or "junior doctorate," and the "higher doctorates" such as the Doctor of Science degree, which is generally awarded to highly distinguished professors. A doctorate is the terminal degree in most fields. In the United States, there is little distinction between a Doctor of Philosophy degree and a Doctor of Science degree. In the UK, Doctor of Philosophy degrees are often equivalent to 540 CATS credits or 270 ECTS European credits, but this is not always the case as the credit structure of doctoral degrees is not officially defined.
