Final answer:
To sit for the national board licensing exam, a person needs to have graduated from an accredited medical school. Residency, fellowship, and passing USMLE Step 1 are important steps in medical education but are not direct prerequisites for the initial licensing exam.
Step-by-step explanation:
To sit for the national board licensing exam in most states, a person is required to have graduated from an accredited medical school. Occupational licenses are a form of credentialing that show a worker has completed the required education or passed a certain test. For medical professionals, obtaining a license is a critical step in establishing their qualifications and ensuring they can practice medicine legally. While the specifics can vary by state, one consistent requirement for doctors across the United States is to graduate from an accredited medical school before sitting for the board licensing exam.
It is important to note that while residency and fellowship are important stages in a doctor's education and career development, they are subsequent steps after medical school and are not prerequisites for sitting for the initial licensing exam. Passing the USMLE Step 1 is a part of the process of becoming a licensed physician but it is a step that occurs during medical school and not a direct requirement for sitting for the national board licensing exam.
