How Long Does it Take to Become a Nurse?


Depending on the time you are able to commit to your nursing education, you may be able to complete the following programs quickly. Below is the average amount of time it takes to complete various nursing programs.

There are differences in the types of duties and skills required for each type. To become a CNA takes about 4-12 weeks of training while an LPN takes about 12-18 months. To be RN requires significantly more training including either a two-year degree or three-year diploma.

With a bachelor of science degree, an RN may go on to become an MSN and seek other specialty certifications. An MSN may even go on to earn their DSN or a DNS which stands for Dr. of Nursing Science.

How Much Can I Make as a Nurse?

According to the U.S. Bureau of Labor Statistics, the median wage for nurses by role:

  • CNA – $29,660
  • Licensed Practical Nurse (LPN) or Licensed Vocational Nurse (LVN) – $47,480

Types of Nurses

If you were to divide the nursing profession into three categories, they would be nursing assistants, practical nurses, and professional nurses. A Certified Nursing Assistant is known as a CNA. A Licensed Practical Nurse is known as an LPN. And a professional nurse is referred to as an RN or Registered Nurse.

Certified Nursing Assistant (CNA) Requirements

Certified Nursing Assistants (CNAs) provide hands-on healthcare to patients in medical settings under the supervision of an LPN or RN. CNAs assist patients with bathing, dressing, and any other basic activities involved in daily life.

Becoming a CNA requires an individual to have a high school diploma or GED and nursing assistant training. Programs for nursing assistant training are typically available through trade schools and community colleges. You can find a school near you here.

Upon successful completion of CNA training, you will be required to pass a CNA certification examination. The exam is made up of two parts – written and practical. The written exam is made up of multiple-choice questions and is typically taken in a classroom setting. It takes about 1.5 hours to complete the exam.

The second part is the clinical exam. It is administered one person at a time by a single test proctor/observer. This part of the exam only takes about 30 minutes where individuals are tested on four skills, selected at random, to demonstrate competency.

Licensed Practical Nurse (LPN) Requirements

Practical nurse education takes around 12 months of training. Sometimes the training can be completed faster depending on the amount of time the student is able to dedicate.

After graduation, a diploma is usually received. Then the graduate will be ready to take the National Council Licensure Exam for Practical Nurses, also known as the NCLEX-PN exam.

After successfully completing the NCLEX-PN exam you become an LPN. As a result, you will be able to check vitals, take blood samples, assist with transporting patients, and generally tend to a patient’s needs. As an LPN, you will have the skills necessary to work at places like a doctor’s office, a clinic, or even with a home healthcare agency.

A licensed practical nurse will work in a structure where they will be performing their duties under the supervision of a physician and possibly be working under the supervision of an RN as well.

The next definite career advancement for an LPN would be to get an associate’s degree in nursing (ADN). This would involve 12 to 18 months of college classes and result in being qualified to become a licensed RN.

Registered nurse (RN) Requirements

A professional nurse is a person that has obtained a college degree in nursing and has also passed the National Licensure Exam or the NCLEX-RN. A licensed registered nurse is able to perform a professional assessment of the medical history of the patient and has the ability to diagnose symptoms.

A licensed registered nurse takes an active duty in administering treatments and diagnostic exams in conjunction with the physician who may be assigned to the patient. As an active team member in diagnosing in administering medication, the RN has many career opportunities in the form of advancement as they are able to specialize in various procedures forms of care like surgical nursing or oncology for example.

Bachelors of Science Versus Masters Degree – BSN vs MSN

After an RN receives a Bachelor of Science in Nursing (BSN) from an accredited nursing school, the next opportunity is to obtain a Master’s degree in nursing (MSN).

With an MSN, you can become an APN or an APRN. Nurses with MSN can then focus on specialties such as forensic nursing, or becoming a clinical nurse specialist.

Nurses with master’s degrees can earn over $100,000 per year or more especially after working their way into a specialty position that requires more certification. Many employers will be happy to help with the cost of obtaining a Master’s degree. An example of a high paying nursing position would be a CRNA which stands for certified registered nurse anesthetist.

Doctor of Nursing Practice

At the highest level of nursing, you can become a DSN or a DNS which stands for Dr. of nursing science. This is most common for people seeking a career as a researcher or a professor at a nursing college.
