I do not work because I am a mom, and that's a whole other job in and of itself. There is a lot more work involved in graduate school. I say to take the time to feel out what your schedule will be like first before attempting to work. Take into account the amount of class time you will be doing, then double that for studying/homework. If you happen to not have clinical duties one semester, that may be the best time to do a part time job. I do not recommend anything over 20 hrs a week if you so choose to do this. Once clinical work begins, it becomes much harder, especially depending on the amount of clients you can get. My school can give up to 3 clients per semester during our internship practicums. However, keep in mind that the externships do not care about your job responsibilities, they feel your responsibility is to the case load you are responsible to serve. Hope to God that your externship supervisor doesn't drop their entire caseload on you and tell you to go. LOL unfortunately it happens. Good luck!
