Use actual recent work, responsibility and knowledgeable explanations relevant to the assignment. Employment dates alone do not establish what the applicant can do.
Connect the record with the work still required
Identify problems handled, process decisions or support responsibilities, with accurate attribution and dates. Explain changes since older records were created. A historic training certificate may provide context without proving current capability. Do not invent recent examples or represent a former team’s collective work as the applicant’s individual knowledge.
Revision histories that name the employee, commissioning records for a system built in-house, an internal manual they wrote, and purchase files showing standard equipment was modified to a specification all speak without adjectives. Confidential material can usually be described without being disclosed: an index listing identifiers, titles, revision numbers and effective dates conveys the shape of a controlled system while the content stays with the employer. Where confidentiality limits what the employer will release, agree in advance on a substitute that still settles the point: a redacted document, a description of the system prepared by someone senior, or a statement from the person who supervised the work.
