There are several issues the bear on your question and the topic is confusing, even to seasoned professionals, but it is good you are asking it as you look ahead. There is a national exam, the EPPP, that most if not all states use as a benchmark, at least for initial licensure. However, each state has specific rules for licensure there that effect when you take the exam (before or after degree) and the "passing" score. Each state also defines what an acceptable internship is as well and the specifics (how many weeks or hours pre-doc, etc) and whether they require APA (only Mississippi and Oklahoma require it currently, I believe). For example, in California you can do an APA, APPIC or CAPIC internship--and there are some additonal alternative routes defined in the law as well for accruing supervised professional experience. (I know someone who did it all post-doctorally because her developmental psych program did not require internship.)So there are two things you need to stay alert to (and your school should be helping you with this): 1) Knowing the regulations for the state in which you want to be licensed initially (read the regulations yourself, don't rely on someone else's proclamation) 2) Following the profession's work on licensure mobility. Each state has slightly different requirements and right now it is not always easy to move and be quickly re-licensed. Work is being done on this but it is slow so if you are planning to be elsewhere it is a good idea to become familiar with their laws or even consider seeking your initial licensure there. You can go to school in one state and be licensed initially in another. Schools and internship sites should be willing to talk with you about how and where their students have been readily licensed
