Training may help explain how knowledge developed, but its price does not establish the standard. Describe the relevant special or advanced knowledge and its actual application.
Avoid a spending proxy
A costly general course is not automatically qualifying organizational knowledge.
If training another employee would take substantial time, document the factual basis when relevant rather than presenting a large estimate as legal proof. Because specialized-knowledge cases attract such requests, the company should treat the premium-processing window as a minimum and add time for a possible response. For costs, identify the internal subject-matter people whose time is needed to explain the knowledge and protect sensitive material. Preparation costs are higher than average because the specialized-knowledge and offsite-control evidence has to be built from internal records. The common mistake is paying to evaluate impressive credentials that do not prove the internal process knowledge actually claimed. Confirm whether a quoted review covers technical material, since specialized documents often sit outside a standard scope and reappear as a separate invoice.
