Wikipedia:Did you know/Guidelines

This is a complete handbook of all of DYK's guidelines and standard practices. It is more helpful as a reference than a guide – if you're looking for a guide on how to do a specific job, see the reviewing, prep building, and admin instructions.

To some extent, DYK approval of a nomination is a subjective process. No amount of studying this page can guarantee approval, nor will violating any guideline or precedent guarantee disapproval. Just because an unfamiliar criterion is not listed does not mean a nomination cannot be disqualified. The subjective decision might depend on an attempt to circumvent the details of the rules, especially if the attempt does not address the underlying purpose of improving the hook and article.
