A PhD is an abbreviation for a degree and it stands for Doctor of Philosophy.
Itâ€™s part of the highest standards of education and often has many prerequisites or requirements. Those who obtain a PhD are often referred to as â€śDoctorsâ€ť.
However, this doesnâ€™t necessarily mean â€śDoctorâ€ť as in the medical practitioner. There are doctors of all subjects and fields.
A doctor of medicine and a doctor of geology are both doctors in different careers.
A person cannot simply just apply for a PhD in university. They need to first complete a list of other degrees before they even become eligible for a PhD.
Itâ€™s worth noting that these pre-requirements differ depending on the country. This is because ever country has their own educational system with different standards.
Generally, a person who enrols for a PhD should have excellent marks during their school years and have at least completed their Bachelor's degree, Honours degree and usually also a Masterâ€™s degree, all of which need to be passed with certain grades.
The process of completing a PhD is intense and it requires full focus and dedication with hours upon hours of research. This is a full time commitment that lasts for anywhere between 2 and 6 years or longer, depending on the subject and subject matter.
