The practicum hours are usually completed toward the end of your degree program, so you have plenty of time to consider the type of placement you prefer and to make arrangements.
Because your MSN program must approve your site and verify your preceptor’s qualifications, it’s best to submit your request 60-90 days before your practicum is scheduled to begin. That way you and the professor overseeing your practice experience have time to work out any issues that arise. It can also take time for your program to confirm all details with the local hospital, healthcare facility or other institution hosting you.
