When should I apply for a new grad nursing position if I graduate with BSN in May 2023?

As for WHEN, I would suggest looking for an apprenticeship program while in your last year of nursing school. HCA hospitals in Las Vegas have these as well as other HCA hospitals nationwide. This is helpful if you want to get a more advanced position like ICU right after graduation. They call them a nurse apprenticeship program and are very competitive.

When to apply for a new graduate position depends on how often the hospitals in your area are hiring. Some (like in Las Vegas) post those positions the month students are graduating, and multiple times a year. Draft your resume in April 2023, ask a professor you like to review it, maybe set up some MOCK interviews with friends, and start checking for postings around the beginning of May of 2023.

would start applying 6 months in advance.for a nursing residency or internship. I had great success and ended up with 3 offers.
