Use genuine records of completed learning and practical application, with dates and the applicant’s actual contribution.
Distinguish attendance from application
A course record may show participation without establishing advanced knowledge. Explain what was learned and how it was used in relevant work rather than relying on a certificate alone.
Internal documents that predate the petition carry the most weight: the written protocol itself, its revision history, training material, and records showing how few people are qualified on it. The company's own written procedures and work instructions, records showing which of them the employee authored or revised, training materials they developed, and correspondence showing decisions escalated to them. The version history of the methodology library or manual showing the planner's name against the revisions over several years, supported by the training records showing the planner taught it to others. Preserve original tickets, change logs, training records, and supervisor explanations; redact customer secrets only as needed while retaining context. Signed procedure records, approved deviation reports, validation protocols and handover notes all qualify; a credit list does not, because it names participation without locating it. Assemble the chronology from records that already exist: project assignments, internal training registers, release notes bearing the person's name, handover documents.
