Nursing is one of the most flexible professions in the working world today. Going back to school to become a nurse is something that is feasible for almost anyone, not matter what their age and background.

Education for nurses comes via several pathways. An Licensed Practical Nurse (LPN) generally goes to a specialized training school for at least a year. Financially, an LPN makes much less than an Registered Nurse (RN), and many jobs aren’t open to LPNs.

To become and RN, a credentialing examination must be successful passed. The credentialing exam covers the primary areas of medical, surgical, psychiatric, and maternal-child health. Pharmacology, critical thinking, and theory and practice are part of the exam. Once this exam is passed, a student officially receives the designation of RN.

In order to take this exam, a student must graduate from an accredited program of nursing. At one time, these programs consisted of two, three and four-year programs. Currently, only the two and four-year programs are available.

A student graduation from a two-year program earns an Associate’s Degree in Nursing (ADN). Graduating from a four-year program means that a student receives a Bachelor’s of Science in Nursing degree (BSN). There is no difference in the credentialing exam for these two degrees: once the NCLEX-RN exam is taken and passed, a person becomes a Registered Nurse.

At this time, pay scales for RNs vary only slightly between those graduating with ADN degree or a BSN degree. Many BSN RNs later go on for a higher level degree, prepare to teach, or have an interest in management positions.

Newer programs offer "fast tracks" for diploma (three-year programs, which became obsolete in the 1980's) and ADN nurses to gain their BSN degrees. There are also special programs for those who already have a Bachelor’s degree in another field to "fast track" through a program and gain a BSN more quickly.

Students can enter right out of high school, and much later as second career choices.

Nursing provides great flexibility. Full-time, part-time and "as needed" positions are often available, particularly in the hospital setting. Shift hours can vary, and can be anywhere from 4 hours to 12 hours in length.

Nurses work everywhere. Hospitals and doctor’s offices are only two of the possible venues. RNs work in schools, corporations, the military, insurance and pharmaceutical companies, in hospices and home health, in universities, and even as consultants to the legal field.
