In the US one seldom reads about Master and much more about Graduate schools. I have the feeling that Graduate school can also mean doing a doctorate/pursuing a PhD degree; thus I am confused with the lack of clear separation here as it isn't a problem with the European distinction of Bachelor, Master, and Doctorate.
Is there a general rule that can be applied to understand what educational level is meant? Like for PhD there is an department admission process required and for Master there isn't, or something like this?
Moreover, one could say to have graduated from High school, from college, from Master's...from kindergarden if you want. Wouldn't it therefore be more logic not to use "graduate" when talking about some specific educational level and instead use terms such as Bachelor, Master, PhD?
