The problem, MNHID, as you can see, is that in some contexts the word "education" is itself a subject. If you want to become a physics teacher, for example, you need to obtain a qualification in education, in addition to your qualification in physics.
In essence, it is not enough to know the subject that you want to teach, but you also need to learn how to teach.
What you apparently wanted the question to be is something like "Tell me about education. Do you have any qualifications?"
An obvious answer to might be "I have a bachelor's degree in law from Glasgow University."
