There are departments in many schools that offer "hybrid" majors, such as:
- Computer Science and Engineering
- Electrical and Computer Engineering
- Electrical Engineering and Computer Science
- Materials Science and Engineering
- Molecular and Cellular Biology
- Nutritional Science and Toxicology
etc.
Let us say you earn a degree in the respective area of one of these majors.
For example, let's say you earned an M.S. in Computer Science and Engineering.
Continuing with this example, let's say that down the road, you are asked to certify that you have the degree in one of the majors (say, an M.S. in Computer Engineering).
Are you ethically/legally/etc. (as the case may be) allowed to claim that you have such a degree? Or are you only entitled to claim that you have exactly the degree written on your diploma/transcript and nothing else, even if it seems like a subset of what is written?
Notes:
If the answer differs between the Bachelor's, Master's, or Doctorate degrees, please explain each one.
If the answer is different for different majors, please explain how/why. And if the answer is different in different situations -- e.g. if it is different in different countries -- please explain how and give typical examples for each case, keeping in mind #3 below.
Obviously, in some cases, you may even be technically allowed to falsely claim you have a degree. I am ignoring such cases here; for the purposes of this question, assume I am only talking about cases where it is indeed not okay (either legally or ethically) to falsely claim you have a degree.
