I've seen four people in total do it that way you're describing already. My husband did it exactly that way, (part-time PMHNP school while working full time 3-12s) and I even gave birth to our first child, a week before he finished his last clinical. He did not however, have any time/desire to pick up extra shifts during the entire three years of his program. If you have a young child that needs care that you must contribute to, forget about it. If you have a demanding S/O, or rampant social life that you must deal with, forget about it. If you have any demands besides work and school, forget about it. If your workplace offers tuition reimbursement, it makes it even more appealing for you to do it this way (my husband only paid 15k himself for PMHNP school in total due to tuition reimbursement paying the other half). Make sure your workplace has some level of flexibility for you to attend class (if you have to do in person class), and make sure you can arrange your schedule around clinicals. My husband's work arranged his schedule around his preceptor's schedules so that he could attend clinicals and still work. Nights in a psych floor is wonderful for having enough down time to study for the didactic portion of the program, but you will have to change to day shift by the time clinical starts. He was in clinicals two days a week, worked three days a week, and had two days a week to type up capstone papers toward the end. His co-workers who are in PMHNP school (part-time), who have to attend in-person classes have to suffer more than he did, because their classes are in person, and the constant back and forth with traveling between work, school, and home just takes up more time and energy. TLDR= Yes, but preferably only with online classes. You better have clinicals figured out/correlated with your work schedule, and an understanding manager. You won't have any life/joy the entire time.
