<p>Different nursing programs require different number of years or hours of clinicals. Some programs require 4 years of clinicals (and as many as 1600 hours) and others require 2 years and as few as 600-700 hours (at least that is as few as I’ve heard). Many/most programs require you to rotate through the different departments so that you can be familiar with each. Some allow you to spend additional time (usually as a senior) in the specialty that you prefer.</p>
