What is the Difference Between PhD and DSc?

The main difference between a PhD and a DSc lies in their focus and the nature of the academic work required for each degree.

• PhD (Doctor of Philosophy): This is a common doctoral degree that can be pursued by students from various academic backgrounds, including science, social sciences, and humanities, if they are interested in a career in academia. A PhD is awarded for the completion of coursework, research, and a thesis that contributes to the advancement of knowledge in the chosen field.
• DSc (Doctor of Science): This is a doctoral degree restricted to science and engineering streams and is awarded in countries where it is in vogue. A DSc is a higher doctorate degree than a PhD and is typically awarded for a portfolio of work, including an over-arching critique of that portfolio. It is often awarded later in an academic's career and requires a higher level of achievement compared to a PhD.

In terms of academic standing, a DSc is considered to be superior to a PhD, as it is an elite qualification and an academic title that signifies outstanding achievements in the field. However, in some countries, the two degrees are considered equivalent. Both degrees entitle the holder to use the title "Doctor" as a form of address.

Comparative Table: PhD vs DSc

Here is a table summarizing the differences between a PhD (Doctor of Philosophy) and a DSc (Doctor of Science):

In summary, while both PhD and DSc are doctoral degrees that require original research, the main difference lies in the field of study and the level of distinction required. A PhD is awarded in various academic disciplines, including STEM fields, while a DSc is primarily awarded in STEM fields. Additionally, a DSc is considered a higher degree than a PhD and requires candidates to have already completed a doctoral degree and undertake additional research.
