The number of clinical areas varies based on a few factors: the length of time the site has been open, the size of the site and the needs of the site. For new sites opened within the last two years, one to two clinical areas are typically opened every three months. For smaller sites, for example an acute care site with a relatively low number of beds, fewer areas are available because the site will have fewer clinical areas overall. The needs of the site also play a role – Some sites will need more students in certain clinical areas and thus may have fewer open clinical areas.
