Nursing is a diverse field with many levels of education, roles, and specialized practice areas. If you are considering a career in nursing or want to learn more about the field, this article will provide an overview of the different levels of nursing and what each entails. From licensed practical nurses (LPNs) to advanced practice registered nurses (APRNs), you’ll discover the various levels of education required to enter the profession, the roles and responsibilities of each type of nurse, areas of specialization, and career advancement opportunities in the nursing field.

Education and Training Requirements

When pursuing a career in nursing, it’s vital to understand the different educational requirements and training options available for various roles. Let’s dive right into it.

Licensed Practical Nurse (LPN) or Licensed Vocational Nurse (LVN)

To become an LPN or LVN, you’ll need to complete a practical nursing program accredited by your state’s board of nursing. These programs typically take about one year to complete and combine classroom instruction with supervised clinical practice. Some topics covered include anatomy, physiology, nursing fundamentals, and pharmacology.

After completing the program, you’ll need to pass the National Council Licensure Examination for Practical Nurses (NCLEX-PN) to receive your license. Some states also require LPNs or LVNs to complete additional training or education, such as continuing education units (CEUs) after licensure.

Registered Nurse (RN)

To become an RN, three educational paths are available: a diploma, an associate degree, or a bachelor’s degree in nursing. Nursing diploma programs are usually hospital-based and take 2-3 years to complete. Associate degree in nursing (ADN) programs take about 2 years and are offered at community colleges. Bachelor of Science in Nursing (BSN) programs take 4 years and are offered at colleges and universities.

While all three pathways can lead to RN licensure, a BSN degree may provide more career advancement opportunities and better preparation for graduate-level nursing programs. After completing your education, you must pass the National Council Licensure Examination for Registered Nurses (NCLEX-RN) to receive your license.

Advanced Practice Registered Nurse (APRN)

APRNs typically hold at least a Master of Science in Nursing (MSN) degree and in some cases, a Doctor of Nursing Practice (DNP) degree. These professionals are further specialized into four roles: Nurse Practitioners, Certified Nurse-Midwives, Clinical Nurse Specialists, and Certified Registered Nurse Anesthetists.

Education programs for APRNs generally involve 2-4 years of study, depending on the initial nursing degree, and focus on advanced practice nursing concepts, research, and specialty-specific coursework. After completing the required education for their specialty, APRNs must pass a certification exam and maintain their certification through ongoing professional development and continuing education.

Areas of Specialization

Pediatric Nursing

Pediatric nursing is the branch of nursing that focuses on providing care for infants, children, and adolescents. This specialization requires a unique set of skills, in addition to general nursing knowledge, to effectively address the specific health challenges and developmental needs of younger patients.

As a pediatric nurse, you must be adept at building trust with your young patients as well as proficient in addressing their physical, emotional, and developmental needs. The scope of pediatric nursing includes administering vaccinations, performing routine wellness checks, and providing treatment for common childhood ailments such as the flu, asthma, and respiratory infections. Additionally, you may be called upon to educate families and guardians on proper nutrition, safe practices, and preventative care measures.

Many pediatric nurses work in hospitals, while others may find employment in pediatric clinics, schools, or specialty care units. In some cases, nurses may choose to focus on specific pediatric sub-specializations such as neonatal nursing or pediatric oncology. Pediatric nursing is a rewarding field that allows you to make a profound difference in the lives of young patients and their families.

Oncology Nursing

Oncology nursing involves caring for patients with cancer at various stages, from diagnosis to treatment and beyond. Oncology nurses play a critical role in cancer management, working closely with multidisciplinary teams that include oncologists, radiologists, and surgeons.

As an oncology nurse, your responsibilities will generally include assessing patients, administering chemotherapy and other medications, managing side effects, and offering emotional support to both patients and their families. Oncology nurses must have a comprehensive understanding of cancer types and treatments, as well as the ability to adapt to advancing technologies and treatment methods in the constantly evolving field of oncology.

Oncology nursing is a challenging profession, but it offers immense personal and professional satisfaction as you have the opportunity to change the lives of people suffering from this devastating disease. A few specialized options within oncology nursing include breast cancer nursing, pediatric oncology, radiation oncology, and surgical oncology. Oncology nurses may work in a variety of settings, including hospitals, cancer centers, and home healthcare agencies.

Critical Care Nursing

Critical care nursing focuses on caring for critically ill patients, often in life-threatening situations. These nurses work in high-stakes environments, such as intensive care units (ICUs) and trauma centers, where patients require constant monitoring and support to maintain their health and stability.

As a critical care nurse, you will collaborate closely with physicians and other healthcare professionals to develop and implement medical intervention plans, administer medications and treatments, and make urgent decisions regarding patient care. Successful critical care nurses require strong analytical and problem-solving skills, as well as the ability to perform well under pressure.

Critical care nurses often specialize in various areas, such as trauma nursing, pediatric ICU nursing, or burn ICU nursing. The field offers a challenging yet rewarding environment for nurses looking to significantly impact the lives of patients and their families in times of crisis.

Career Advancement Opportunities

Clinical Nurse Specialist (CNS)

Clinical Nurse Specialists are advanced practice registered nurses (APRNs) with clinical expertise and leadership skills. They work across a spectrum of healthcare settings, including hospitals, clinics, and long-term care facilities, and specialize in a specific patient population, type of care, or clinical specialty.

As a CNS, your responsibilities generally include direct patient care, collaborating on research projects, mentoring and educating nursing staff, and influencing healthcare policies and practices. To become a CNS, you will need to earn a master’s or doctoral degree in nursing and, in some cases, obtain additional certification in a specialized field. This rewarding career allows you to substantially impact patient outcomes while leading and shaping the nursing profession.

Nurse Practitioner (NP)

Nurse Practitioners are APRNs who have completed a master’s or doctoral nursing program, allowing them to provide high-level medical care to patients. NPs serve a vital role in the healthcare system, filling the gap between nurses and physicians and often act as primary care providers. With their advanced training and education, NPs can diagnose and treat medical conditions, prescribe medications, and order and interpret diagnostic tests.

As an NP, you can choose to work in a specific area of specialization, such as family practice, pediatrics, geriatrics, or mental health. NPs often enjoy a higher level of autonomy in their practice, especially in states with favorable practice regulations. Pursuing a career as a Nurse Practitioner allows you to take on a more independent, decision-making role in patient care while remaining true to nursing’s mission of patient-centered care.

Nurse Anesthetist (CRNA)

Certified Registered Nurse Anesthetists (CRNAs) are highly specialized APRNs responsible for administering anesthesia to patients during surgeries and other medical procedures, as well as managing their pain and sedation. CRNAs work in collaboration with anesthesiologists and surgeons and are an essential part of the healthcare team.

To become a CRNA, you must complete a master’s or doctoral program in nurse anesthesia, gain significant experience in critical care nursing, and pass a national certification exam. The field of nurse anesthesia is both challenging and lucrative, offering nurses the opportunity to play a pivotal role in patient care during some of the most critical moments of a patient’s surgical experience.

Each career advancement opportunity provides unique benefits and challenges, allowing nurses to tailor their careers to their individual interests and career goals. No matter which path you choose, all options offer the potential for personal and professional growth, impacting the lives of patients and the nursing profession as a whole.


The nursing profession is diverse and offers several levels of education, roles, and specializations.
