I found this information in ECFMG website , can someone explain me how it works ?
ECFMGs electronic Credentials Verification is free for medical schools and makes the process of verifying credentials faster, easier, and more efficient! Through this program, authorized medical school officials can verify the credentials of their schools graduates over the Internet rather than using the traditional paper-based process. For example, schools can use electronic Credentials Verification to verify the credentials of their graduates who apply for ECFMG certification and for the United States Medical Licensing Examination® (USMLE®), eliminating the need to complete Verification of Medical Education Form 327-A.
