Re: working PT as a new grad
Where I am going to be working (NICU) when I graduate full-time is required for the same reason Tazzi stated. They have a specific training period, new grads start on the same date and that's that

.
On the med/surg floors, though, they do have a PT option, although they prefer full-timers. Especially if you've worked as an LPN (which I did) they figure you have a good running start and are willing to let preceptorship take longer.
If you can't work FT, it's worth asking around.
