Ranking Criteria is a set of rules and guidelines set by the QAT to ensure that every player can expect similar game play throughout every beatmap.

Beatmapping is the process of a creator creating a beatmap. This process includes: selecting music, timing and mapping the beatmap, and testing the beatmap. It might also include: adding a video, adding a storyboard, and/or adding a custom skin. All of those can be done by the creator alone or with other users, sometimes referred to as storyboarders, skinners, and/or guest creators, depending on what they do.
See also: Modding.
Modding is the process of users reviewing (or commonly called "modding") a creator's beatmap in the pending (or work in progress/help) stage. Modding plays a big role in quality control because this allows creators to fix issues with their beatmap.
