Records should accurately identify when and where the experience occurred.
Preserve genuine historical facts
Explain the transaction and relevant organizations rather than attributing past training to an entity that did not provide it. The actual chronology needs assessment.
Contemporaneous records: internal specifications with the transferee named, development and validation reports, revision histories, training materials the transferee wrote and problem reports the transferee resolved. A completed assessment form carrying the applicant's rationale in the comments field, an escalation the applicant wrote and its outcome, a procedure revision listing them in the change history: each demonstrates application of the method. Attach the artefacts rather than describing them: the specification the applicant authored, the change log bearing their name, the validation report they signed, the training material they wrote for the team that followed. A protocol document with its revision history, a validation dataset, an internal method note, a training deck the applicant wrote: each is a concrete object that can be described and, where confidentiality permits, produced in redacted form.
