How to Become a Doctor

The first step towards becoming a doctor is to complete a bachelor’s degree. Although there is no specific major required for medical school, it is common for aspiring doctors to pursue degrees in pre-medical or scientific fields such as biology, chemistry, or biochemistry.

2. Take the Medical College Admission Test (MCAT)

After completing a bachelor’s degree, aspiring doctors need to take the Medical College Admission Test (MCAT). This standardized exam assesses their knowledge and skills in areas such as biology, chemistry, physics, and critical thinking. A good MCAT score is essential for getting accepted into medical school.

3. Complete Medical School

Once accepted into medical school, students undergo four years of intensive education and training. The first two years typically focus on classroom learning and laboratory work, while the last two years involve clinical rotations, where students gain hands-on experience in various medical specialties.

4. Pass the United States Medical Licensing Examination (USMLE)

After graduating from medical school, aspiring doctors must pass the United States Medical Licensing Examination (USMLE). This three-step exam assesses their ability to apply medical knowledge, skills, and principles in patient care settings. Passing the USMLE is a requirement to obtain a medical license.

5. Complete Residency Training

After passing the USMLE, doctors must complete residency training in their chosen specialty. Residency programs typically last three to seven years, depending on the specialty. During this time, doctors work under the supervision of experienced physicians and further develop their clinical skills.

6. Obtain Medical Licensure

Once residency training is completed, doctors must obtain medical licensure to practice medicine independently. The requirements for medical licensure vary by state, but generally involve passing a state licensing exam and meeting other criteria such as completing a certain number of continuing medical education credits.

7. Consider Further Specialization

After obtaining medical licensure, some doctors may choose to pursue further specialization through fellowship programs. Fellowships provide additional training and expertise in a specific area of medicine and may be required for certain subspecialties.


Becoming a doctor requires years of education, training, and dedication. It is a rewarding career path that allows individuals to make a positive impact on the lives of others.
