After graduating from an undergraduate degree, a person can carry on at university to do a Doctorate Degree. This is the highest degree that can be awarded by a university. The most common doctoral degree is a Doctor of Philosophy, known as a PhD. A person can be awarded this degree in lots of different subjects.
A Vocational Qualification is a work related course. For example, a Librarianship Qualification or a Law Conversion Course. They are to help the person to gain particular skills for the chosen subject which may not have been taught at university.
Two common terms are "Graduate degree" or "Masters Degree". However, you might hear this course of study referred to as simply "masters" or "grad school"
Example sentences:
"Are you going to pursue a Masters degree this year?"
"Tom received his Graduate degree from a university in the United States."
"Where did you go to grad school?"
"I am working on my masters in business."
"Graduate degree"（大学院の学位）と"Masters Degree"（修士号）という２つの一般的な言葉があります。ただ、シンプルに"masters"や"grad school"と呼ばれることもあります。

The educational level beyond an undergraduate degree is usually called "postgraduate" or "graduate school". Sometimes people shorten the phrase "graduate school" to "grad-school".
For example, you can say:
-Now that I have my undergraduate degree, I want to go to grad-school.
-Sam wants to go to graduate school so that she can be a lawyer
-I am a postgraduate student and everything at postgrad/postgraduate level is very different from what I learned in my undergraduate/undergrad degree.
Remember, the word "grad" is usually a shortened version of the word "graduate"
学士号を取った後の教育レベルのことを"postgraduate"（大学卒業後の）または "graduate school"（大学院）と言います。"graduate school"を省略して"grad-school"と言う場合もあります。
例：
-Now that I have my undergraduate degree, I want to go to grad-school.
学士号は取ったから、大学院に行きたい。
-Sam wants to go to graduate school so that she can be a lawyer
サムは大学院に行って弁護士になりたいと思っている。
-I am a postgraduate student and everything at postgrad/postgraduate level is very different from what I learned in my undergraduate/undergrad degree.
私は大学院生ですが、このレベルでは全てが大学で学んだこととは違います。
"grad"は普通、"graduate"の省略形として使われます。
英語で大学は”University"また”College"で、大学院は”Graduate school"と言います。

Graduate school students（大学院生）= graduate students

(彼はもうその大学院に行きません。)
-She wants to continue studying as a graduate student.
(彼女は大学院生として勉強を続けたいと思っています。)

After finishing your first years of university, students have the option to continue their studies at a more advanced level, which we call Graduate school or Grad school for short.
Typically in Grad school, you are studying to receive what is called a Master's degree, which is typically given to you after choosing and studying a subject at this higher level. We call these a Master's program.
