The sponsor expects retention. The table does not explicitly list the item. And the RC must make a determination: is this record essential?

This is not a hypothetical dilemma. It is the kind of question that arises routinely at any site running more than a handful of studies, because no list -- however comprehensive -- can anticipate every record that every trial design will generate. ICH E6(R3) anticipated this problem. That is why Appendix C, Section C.3 provides not just a table of essential records, but a set of criteria for determining essentiality. The table is the product of those criteria. The criteria are the tool.

This lesson teaches you to use that tool. Not as a memorization exercise -- nobody benefits from reciting 28 lettered criteria -- but as an analytical framework that governs what your site's records infrastructure must be designed to accommodate.
