Are you ready to discover your college program?

Data from the Kaiser Family Foundation indicates there are slightly more than 900,000 physicians practicing medicine in the US. Yet, behind this number is a crushing need for still more doctors: A 2013 report from the American Association of Medical Colleges projects there will be a national shortage of about 46,000 to 90,000 physicians by 2025. Joining the ranks of doctors to fill this shortfall requires a substantial amount of time and effort. The following guide explores the steps to become a doctor, reviews medical school admission requirements, discusses medical school training and offers an overview of physician careers.

How to become a doctor

Developing the skills and knowledge necessary to practice medicine requires a great deal of time and effort, so it is important to research the training process before taking the plunge. The following section outlines how physicians prepare for their careers.

Step 1
Complete an Undergraduate Education
Medical school admissions boards require all applicants to earn bachelor's degrees from accredited colleges and universities. While there is no specific undergraduate degree recommended for all medical school hopefuls, The College Board lists pre-medicine, biology and exercise science among potential majors.
Step 2
Pass the MCAT Examination
College juniors interested in a career as a doctor should register for and take the Medical College Admission Test (MCAT). The MCAT is a standardized, multiple-choice examination used by medical school admission committees to assess a candidate's likelihood of succeeding in their program.
Step 3
Apply to Medical School
There is no required timeline for applying to medical school. Students generally begin the application process during the summer after their junior year in college, but some choose to take a year off after completing their undergraduate degrees before applying. Most medical schools in the US use the American Medical College Application Service (AMCAS), a centralized application processing service from the Association of American Medical Colleges. Students select their target medical schools and submit a single application to AMCAS, which distributes the application to each institution.
Step 4
Complete Training at Medical School
The path to becoming a physician begins in medical school, which generally requires four years of full-time study beyond one's undergraduate studies. Curriculum is divided between classroom-based instruction in the sciences and clinical rotations where students develop applied skills in various areas of medicine.
Step 5
Pass Parts I & II of the United States Medical Licensing Examination (USMLE)
In order to practice medicine legally in the US, students must take and receive a passing score on the United States Medical Licensing Examination (USMLE), a three-part examination taken during and after medical school. Medical students must pass the first part of the examination, which covers basic medical principles, before entering their third year of studies. During their fourth year, students must pass the second part of the exam, which covers clinical diagnosis and disease development.
Step 6
Match with Residency
During their final year of medical school, students start narrowing down their medical specialty options (e.g. pediatrics, anesthesiology). They submit an application for residency and are matched to open residency programs throughout the country.
Step 7
Graduate from Medical School & Start Residency
Newly-minted doctors transition from graduate school residency programs. These programs generally require at least three years to complete and provide in-depth training in students' chosen specialties.
Step 8
Pass Part III of United States Medical Licensing Examination (USMLE) and Finish Residency
The final step of the residency process is to complete Part III of USMLE. This examination covers clinical management and assesses the doctor's ability to practice medicine safely and effectively.
Step 9
Earn Board Certifications
Once their medical educations are complete, doctors may obtain certification in their chosen field. There are 24 specialty boards that certify physicians in hundreds of specialties and subspecialties. Board certifications require a written and, in some cases, an oral examination.
Step 10
Get a State License
Medical licensure is governed at the state-level by state boards of medicine, and each sets its own licensing requirements and procedures. Trained and board-certified doctors must apply for state medical licenses before they enter the field.
Step 11
Apply for Jobs as a Doctor
The final step to become a doctor is securing a job. Many doctors begin their search during residency. It is common for residents to transition into full-time positions after their residencies end. However, some doctors choose to go on the open market and seek out career openings. Other physicians are contacted by recruiters to fill a position.

What Does a Doctor Do?

Doctor Career Basics

Physicians and surgeons are authorities in the practice of medicine. They assess patients, diagnose diseases and illnesses, and treat a variety of conditions. They may order and perform tests and use those tests to diagnose and treat their patients. Surgeons also perform operations and more complicated invasive procedures on patients. Doctors and surgeons work in a variety of settings, from hospitals and private offices to health clinics and schools.

Doctor Salaries & Job Growth

Doctor Salaries Across the US

Medicine is one of the highest paying occupations in the country. In fact, the Bureau of Labor Statistics reports that doctors account for 45 percent of the 20 highest-paying jobs in the country. Average salaries easily surpass six figures, with some surgeons and physicians able to command salaries greater than $400,000. Numerous factors influence doctors' earning potential, including specialization, education and location. Use the map below to learn more about doctor salaries by state.


Doctor Job Growth

Aging, insurance reform and chronic illness drive steady demand for healthcare services. The Administration on Aging projects that the number of Americans aged 65 and older will account for more than 21 percent of the population by 2040, and the Affordable Care Act expanded Medicare and provided insurance to nearly 17 million people who previously did not have insurance. Finally, according to the Centers for Disease Control and Prevention, early half of the country's population—approximately 117 million people—are living with a chronic disease.

Preparing for a Doctor Career: Medical Schools & Pre-med Programs

Pre-med Programs & Degrees

Undergraduate studies are important for students preparing for the rigors of medical school. Because no specific major is required to be admitted to medical school, most universities do not offer an explicit pre-medicine major. Most students enroll in other disciplines that can provide the experience admissions boards seek in qualified applicants. Two of the most common majors with a pre-med emphasis include biology and chemistry.

Bachelor of Science in Biology

Focus of study

The Bachelor of Science in Biology with a pre-medicine emphasis includes specialized courses that develop students' understanding of organic and general chemistry; the fundamentals of biochemistry and microbiology; and core concepts in human anatomy and physiology. This structured four-year course plan prepares students to take the MCAT examination at the end of their junior year.

Example Courses

Bachelor of Science in Chemistry

Focus of Study

The Bachelor of Science in Chemistry for pre-med students offers a track of coursework in the natural sciences and humanities aimed at preparing competitive candidates for medical school. Curricula emphasize chemistry and biology courses, such as organic chemistry, that satisfy the admission requirements of medical schools. Chemistry programs help students gain key laboratory and research skills while preparing them to take the MCAT at the end of their junior year.

Example Courses

Medical School Admission Requirements

Medical school admission committees enroll students who come a variety of backgrounds, locations and undergraduate programs. Although admission requirements vary from school to school, coursework and testing requirements generally remained unchanged. Below is an overview of common medical school requirements.

Standardized Testing

Students must take and submit scores from the Medical College Admissions Test (MCAT).

Medical School Courses & Requirements

Medical school is a major undertaking that requires dedication and hard work to complete. Learn more about what medical school entails, what students experience during their programs, and what happens after they graduate.

Who is the ideal medical school candidate?

There is no universally ideal medical school candidate. Medical school students come from diverse backgrounds, but most begin directly after finishing their bachelor's degrees. Their undergraduate educations vary – some students study the sciences (e.g. biology), while others major in the humanities (e.g. English).

Medical schools seek candidates that bring diversity to the workforce, are sincerely committed to service and have an unyielding interest in medicine. Attractive candidates should be analytical thinkers with good problem solving skills. They should be strong communicators who can establish relationships with others and make challenging decisions while under pressure.

Are there different types of medical schools?

There are two types of medical school programs in the United States: allopathic (MD) and osteopathic (DO). Both programs take a similar approach to curriculum. However, osteopathic programs place a greater emphasis on holistic and therapeutic treatment techniques.

How long does medical school take to complete?

Medical school curricula traditionally require four years to complete, then students assume residencies that lasts at least three years (but can go upwards of 11 years). Some doctors may go on to complete additional years of training in a fellowship.

What are the requirements in medical school?

Although specific courses can by school, medical school curricula generally follow the same four-year format. The first two years focus on the fundamentals of body structure and anatomy, with coursework in biochemistry, gross anatomy, human organ systems, infectious diseases and pharmacology. During this time, students familiarize themselves with the role of the physician by studying ethics, health law, patient interaction and medical examinations.

In order to move to year three of medical school, students must take and pass Step 1 of the United States Medical Licensing Examination. This test ensures students have learned the core scientific fundamentals required to practice medicine in a competent manner.

During the final two years of medical school, students participate in clinical rotations in primary and specialized care settings. Clinical rotations serve as an opportunity for students to apply their classroom-based knowledge in real-world, supervised experiences with patients. In order to graduate and move into a residency, students must also take and pass Step 2 of the United States Medical Licensing Examination. Step 2 assesses the candidate's medical knowledge and clinical science skills.

Once they've completed their core curriculum and clinical rotations, medical students move to the residency phase of their training.

What is a residency?

As they near their final year of medical school, students begin preparing for residency. A residency is a three- to eleven-year training program where doctors receive specialized professional training guided and supervised by experienced physician educators. Residency length varies by specialty. For example, pediatricians participate in a three-year residency while urologists have five-year residencies. The residency matching process takes nearly a year. Students submit applications through the National Residency Matching Program (NRMP), a process that matches them to open postgraduate residency programs. To complete their programs, residents must pass Step 3 of the USMLE. This examination tests the candidate's clinical assessment and management knowledge and skills.

What is a fellowship?

After finishing their residencies, physicians may choose to complete fellowships in their respective specialties, such as oncology (cancer treatment) or neurology.

Doctor Career Concentrations

Medicine offers many different practice options. The American Medical Association lists more than 200 specialty categories and the Accreditation Council for Graduate Medical Education more than 140 specialties and subspecialties.
