Is there a degree higher than PhD?

There isn't a universally recognized academic degree *higher* than a PhD in the sense of a sequential progression. A PhD is generally considered the highest earned research degree.

However, there are some post-doctoral qualifications and titles that represent further achievements:

* Postdoctoral research positions: These are temporary research positions held after a PhD, often to gain further experience and develop independent research programs. They are not degrees themselves.

* Honorary doctorates (Doctor of Letters, Doctor of Science, etc.): These are honorary degrees awarded by universities in recognition of significant achievement, not earned through academic study.

* Fellowships (e.g., Fellow of the Royal Society): These are prestigious awards granted by learned societies, recognizing excellence in a field. They are not academic degrees.

Therefore, while there are prestigious positions and awards attainable after a PhD, there isn't a higher *academic degree* in the same way that a Master's is higher than a Bachelor's.
