Nursing training schools were popular in North America in the late 1800s because hospitals could be inexpensively staffed by students. This was a cost-effective way to provide healthcare services, which was especially important during a time when hospitals were growing rapidly and there was a shortage of qualified nursing staff. Additionally, the students could gain practical experience while learning and could eventually become licensed nurses, which was essential for the proper functioning of hospitals.
