Other Steps on the Path to Becoming a Doctor

The journey to becoming a doctor doesn’t stop at medical school or even residency. Aspiring physicians must navigate several other steps before they can practice independently. Here’s what to expect along the way.

Passing Licensing Exams – Medical school students are required to pass a series of high-stakes exams to advance and eventually practice medicine. These exams test everything from foundational medical knowledge to real-world decision-making skills and require months of intensive preparation.

• For M.D. students, the United States Medical Licensing Examination (USMLE) includes Step 1, Step 2 CK (Clinical Knowledge), and Step 3, which is typically completed during residency.
• For D.O. students, the equivalent is the Comprehensive Osteopathic Medical Licensing Examination (COMLEX) Levels 1, 2, and 3.

Matching Into a Residency Program – The residency match process is a critical step in a doctor’s training. Students apply for residency through the Electronic Residency Application Service (ERAS) and rank their preferred programs. The process involves crafting a compelling personal statement, gathering letters of recommendation, attending interviews with potential programs, participating in Match Day, where students learn which program they’ve matched with through the National Resident Matching Program (NRMP).

For students who don’t match initially, reapplying the following year or pursuing alternative paths can delay their journey by at least a year.

Securing Medical Licensure – Graduates must apply for a medical license in the state where they plan to practice. Licensure requirements vary but typically include completion of medical school and residency, passing licensing exams (USMLE or COMLEX), and submitting proof of clinical training and competency. This process can take several months to finalize, so planning ahead is essential.

Credentialing for Practice – Before starting clinical work, physicians need hospital and insurance credentialing. These processes verify qualifications and ensure doctors can work in hospitals and bill for services. Credentialing is an administrative step that can take weeks or even months to complete, depending on the healthcare system.

Continuing Medical Education – Even after becoming a fully licensed physician, the learning never stops. Doctors must complete Continuing Medical Education (CME) credits regularly to stay up to date with medical advancements and maintain their board certification. Periodic recertification exams are also required, ensuring physicians meet the highest standards of patient care.
