standardizing
credentialing
acquiescence
licensure

The answer is "credentialing."

Explanation:

When it comes to the medical field, "credentialing" is used as a process in order to ensure the credibility of a licensed medical professional. The validation or inspection is carried out by credentialed inspectors. These inspectors make sure to do a background check of the physician's license and legitimacy.

This allows the hospitals to make sure that the physicians who are working under them are qualified and thus will offer quality care to the patients. The physician, on the other hand, has the responsibility to provide up-to-date documents in order to hasten the process.
