If you are interested in going to RN school, one important point to consider about any school you're investigating is whether or not it's accredited. The National League for Nursing Accreditation Committee (NLNAC) is the national accrediting body for any kind of nursing education program. They set criteria for the schools they evaluate to make sure the institutions maintain a standard of educational quality.
Schools volunteer to be accredited. If you attend an RN school that is not accredited, it can delay your opportunity to sit for your boards (the nursing licensure tests), which can result in a delay of your nursing license.
