The healthcare industry offers a wide array of career opportunities. While certain roles like medical coders or billers may not necessitate extensive education, the vast majority of positions in this sector require significant educational credentials.

According to the US Bureau of Labor Statistics, healthcare employment is poised for significant growth, expected to add more than two million new jobs by 2029, surpassing all other sectors. This surge is driven by an aging population in need of more healthcare services and the continual advances in medical technology and medicine, sparking increased demand for medical researchers and scientists.

This piece delves into some of the premier roles within the healthcare sector, providing crucial information for those contemplating a healthcare career path, particularly regarding educational prerequisites.


A Licensed Practical Nurse (LPN) is integral to patient care, aiding individuals with daily tasks such as eating, dressing, and bathing. In addition to these fundamental responsibilities, LPNs are qualified to administer medications and check vital signs, like blood pressure. They offer indispensable support to Registered Nurses (RNs) and physicians by managing detailed medical records, facilitating communication with patients and their families, and promptly alerting RNs and doctors to any changes in a patient’s health status.

To qualify as a Licensed Practical Nurse (LPN), candidates must earn a nursing certificate from an accredited program, which generally takes more than a year to complete. Furthermore, LPNs are required to pass the National Council Licensure Examination for Practical Nurses (NCLEX-PN) to achieve licensure.

Registered Nurses (RNs) supervise LPNs and other healthcare aides, playing a critical role in treating patients, coordinating care plans, and collaborating closely with doctors. RNs become licensed by passing the NCLEX-RN exam after completing a Bachelor of Science in Nursing (BSN) or an Associate Degree in Nursing (ADN), which can take 2-4 years.

Advanced Practice Registered Nurses (APRNs), such as nurse anesthetists and nurse practitioners, provide primary and specialty healthcare services. APRNs must pass national and state certification exams and hold a master’s degree to practice.

Medical Scientists or Researchers

Medical scientists and researchers are committed to studying diseases, their causes, and formulating innovative treatments and preventive strategies. These experts may possess a medical degree or a Ph.D. in biology or a closely related life science. Engaging in patient-facing roles often necessitates a medical degree.

They are employed by a diverse array of institutions, including universities, hospitals, research facilities, and private companies like pharmaceutical manufacturers. Their work involves formulating hypotheses, planning and executing experiments, and possibly conducting clinical trials to assess the outcomes.

Additionally, most medical scientists and researchers require specialized training in their specific focus areas, such as genomics, gene modification, or DNA sequencing, to excel in their roles.

For those interested in gene editing applications, enrolling in a CRISPR course is recommended as an introductory step.


The journey to becoming a doctor is multifaceted and varies according to the chosen specialty. It begins with a four-year undergraduate degree, followed by four years of medical school. During the last two years of medical school, students engage in clinical rotations at hospitals and clinics. Graduation is followed by a residency training program, which lasts between three to seven years and is essential for licensure.

The American Medical Association (AMA) accredits over 12,000 residency programs, each with specific requirements. For example, internal medicine or pediatrics necessitates a three-year residency, whereas specialties like anesthesiology, obstetrics and gynecology, and psychiatry require four years. Fields like general surgery, radiation oncology, and child neurology demand a five-year commitment, and areas such as plastic surgery, neurological surgery, and interventional radiology require six to seven years.

Doctors typically engage in general medicine coursework before selecting their specialty during residency. Most states require the completion of at least one year of a residency program and the successful passing of a board-certified exam in the chosen specialty for licensure.


Pharmacists are crucial to healthcare, dispensing prescription medications and providing vital patient education on safe medicine use. To pursue this career, individuals must attain a Doctor of Pharmacy (Pharm.D.) degree from an accredited institution. In addition to educational qualifications, pharmacists must obtain licensure, which usually involves passing examinations that assess pharmacy practice knowledge and skills.

Physician’s Assistant

A Physician Assistant (PA) is essential to the healthcare system, tasked with examining, diagnosing, and treating patients under physician and surgeon supervision. Candidates must complete a rigorous Master’s Degree program in Physician Assistant Studies, which merges classroom learning with extensive clinical rotations across different medical environments.

This education prepares PAs to offer a broad range of medical services, from physical exams to prescribing medications. The high demand for PAs stems from their ability to improve healthcare delivery, providing accessible and high-quality care. Graduates must pass a national certification exam to practice, upholding the medical field’s high standards.

Physical Therapist

Physical therapists assist patients in managing pain and improving mobility, often following an injury or illness. They conduct assessments, develop treatment plans, and work directly with patients. PTs require a bachelor’s degree in health science, completion of a Doctor of Physical Therapy (DPT) program, and must pass the National Physical Therapy Examination (NPTE). Licensure is also required.

Occupational Therapist

Occupational therapists are pivotal in aiding sick, injured, or disabled patients to recover or develop the skills needed for daily life and work. They employ personalized treatment plans to help individuals enhance their task performance and independence.

Becoming an occupational therapist requires completing a Master’s Degree in Occupational Therapy, combining theoretical knowledge with clinical rotations for a comprehensive understanding of human development, rehabilitation techniques, and adaptive technologies. Graduates must pass a national certification exam to demonstrate their proficiency in supporting patients through physical and cognitive challenges.

Radiation Therapist

Radiation therapists are key figures in medicine, specializing in the administration of radiation for treating cancer and other diseases. They collaborate with oncologists to create and implement treatment plans, focusing on the precision and safety of radiation delivery. Candidates need at least an Associate’s Degree in radiation therapy, covering radiation physics, anatomy, and patient care basics.

In most states, radiation therapists must also achieve licensure or certification, underscoring their expertise and commitment to industry standards. This process often involves passing a national certification exam and sometimes requires continuing education to maintain professional standing. Through their specialized skills and compassionate care, radiation therapists are integral to patient treatment teams, aiding in recovery and enhancing patient well-being.

The educational routes outlined here serve as a guide to a variety of positions within this vibrant sector, ranging from direct patient care to administrative support. Each role requires specific training and certification, underscoring the importance of specialized education in achieving excellence.
