What is the duration of validity for the TABC seller-server training certificate once completed?

Upon completing the TABC seller-server training certificate, the duration of validity is typically two years, unless it is revoked earlier. This means that individuals who have completed the training will be considered certified for a period of two years from the date of completion. It is essential for individuals to renew their certification before the two-year mark to ensure they remain compliant with TABC regulations. Option A is not correct because the certificate is valid for more than one year. Option B and C are also incorrect as the certificate does not remain valid for five years or indefinitely, respectively.
