I would like to know the best approach on how to document when an individual has conducted GCP training.

Would it be fair to say that for commercially sponsored trials a File Note in a TMF or a site file would be sufficient to say that all GCP certificates are centrally located, hence so when the files are inspected the monitors can refer to the file note which would tell them that all GCP certificates are centrally located in one file and then they can then refer to this central file where ever it may be is this deemed sufficient.

Or would the best approach be to ensure that all the current GCP certificates are available and filed in the site file or TMF so monitors can see that they are present.

Thank You
