Becoming a certified nurse requires completing an accredited nursing program, passing a national licensing exam, and obtaining a state license. The fastest route takes about one year for a practical nursing certificate, while a registered nursing degree takes two to four years depending on the program type. Here’s what each step looks like.
Choose Your Nursing Level
There are two main entry points into nursing, and they differ significantly in time, cost, and what you’ll be allowed to do on the job.
Licensed Practical Nurse (LPN): You need a high school diploma or equivalent and a one-year accredited practical nursing certificate program. LPNs provide basic patient care under the supervision of registered nurses and physicians. You’ll take the NCLEX-PN exam to get licensed. This is the quickest path into nursing.
Registered Nurse (RN): You can qualify through either a two-year Associate Degree in Nursing (ADN), typically offered at community colleges, or a four-year Bachelor of Science in Nursing (BSN) at a university. Some schools offer accelerated ADN programs that finish in 18 months. Both paths lead to the same licensing exam, the NCLEX-RN, but a BSN opens more doors for advancement, hospital employment, and eventual specialty certification.
If you already hold a bachelor’s degree in another field, Accelerated BSN (ABSN) programs compress the nursing curriculum into 12 to 18 months of intensive study.
Meet Nursing School Prerequisites
Before you start a nursing program, you’ll need to complete prerequisite courses. These vary by school but typically include English composition, introductory psychology, college-level math, chemistry, and human biology or anatomy. A common minimum GPA requirement is 2.5, with no grade lower than a C in any prerequisite course. Many programs only allow you to repeat a prerequisite once for a higher grade, so strong performance the first time matters.
Competitive programs often have more applicants than seats. A GPA well above the minimum, strong science grades, and healthcare volunteer experience all improve your chances. Some programs also require entrance exams like the TEAS or HESI.
Complete Clinical Rotations
Nursing programs include hands-on clinical rotations in hospitals, clinics, long-term care facilities, and other healthcare settings. The number of required clinical hours varies by state because each state’s board of nursing sets its own standards. Some states allow a portion of clinical hours to be completed through simulation labs or online instruction, though most require substantial time in real patient care environments.
Clinicals typically begin in your second year (for ADN students) or third year (for BSN students) and rotate through different specialties: medical-surgical nursing, pediatrics, obstetrics, mental health, and community health. These rotations help you discover which area of nursing suits you and build the practical skills you’ll need from day one on the job.
Pass the NCLEX Licensing Exam
After graduation, you’ll take the NCLEX, the national exam required for licensure. LPN graduates take the NCLEX-PN, and RN graduates take the NCLEX-RN. The RN exam tests four major areas: safe and effective care management (patient safety, infection control, legal and ethical issues), health promotion and disease prevention, psychosocial integrity (mental and emotional health care, therapeutic communication), and physiological integrity (body systems, medication knowledge, nutrition, disease management).
The NCLEX uses adaptive testing, meaning the difficulty of questions adjusts based on your answers. The exam ends when the computer has enough information to determine whether you’ve met the passing standard. Preparation typically involves dedicated review courses, practice questions, and several weeks of focused study after graduation.
Apply for Your State License
Passing the NCLEX doesn’t automatically make you licensed. You’ll need to apply through your state’s board of nursing. This process involves a background check, and 36 states require fingerprint-based checks run through the FBI’s identification system. The remaining states use name-based record searches or self-disclosure of criminal history. You’ll pay for the background check yourself, typically $30 to $75.
Each state board reviews criminal history on a case-by-case basis, weighing whether any past convictions pose a risk to public safety. A criminal record doesn’t automatically disqualify you, but serious offenses can. The entire process from passing the NCLEX to holding your license in hand generally takes a few weeks.
If you plan to work in multiple states, the Nurse Licensure Compact (NLC) allows nurses to practice across 43 participating states with a single multi-state license. If your home state is a compact member, you won’t need separate licenses for each state where you work.
Consider Specialty Certification
Once you’re a licensed RN, you can pursue specialty certifications that demonstrate advanced expertise in a particular area. These are separate from your nursing license and are offered by credentialing organizations like the American Nurses Credentialing Center. Available certifications include family nurse practitioner, psychiatric-mental health nurse practitioner, adult-gerontology acute care nurse practitioner, and adult-gerontology primary care nurse practitioner, among others.
Specialty certifications typically require a graduate degree (master’s or doctoral), a set number of supervised clinical practice hours in your specialty, and passing a certification exam. These credentials can increase your earning potential, qualify you for advanced practice roles, and signal deep expertise to employers and patients. Even without pursuing an advanced degree, some certifications for bedside RNs are available in areas like critical care, emergency nursing, and oncology after you’ve accumulated enough practice hours.
Total Timeline at a Glance
- LPN: About 1 year of school, plus a few weeks for licensing. You can be working in roughly 14 to 16 months.
- ADN (RN): 2 years of school (or 18 months accelerated), plus licensing time. Expect about 2.5 years total.
- BSN (RN): 4 years of school plus licensing. About 4.5 years from start to practice.
- Accelerated BSN: 12 to 18 months for those who already hold a non-nursing bachelor’s degree.
Prerequisites can add one to two semesters if you haven’t completed the required science and general education courses before applying. Planning those early, even while still deciding on nursing, can shave months off your total timeline.
