Nursing school is challenging but extremely rewarding. In addition to the classroom requirements, you will also need significant additional training to perfect your bedside clinical skills, including physical assessment and procedures like IV's, and treatments. It's the perfect mix of science and art. There are several potential tracks like Informatics and Research within the discipline of nursing, for different potential candidates.
The duration of education varies, with Associate degrees taking approximately 2 years and 4 years for a Bachelor's Degree. There are also advanced degrees possible, such as a Master's, PhD or DNP (Doctorate of Nursing Practice).
