Three characters on the .org in the X-for-Y form. K4I reads as knowledge for impact, kids for inclusion, or knowledge for innovation.
Knowledge for impact is close to the exact language of the research translation field: the discipline of getting evidence out of journals and into practice. Funders increasingly require it, universities have offices dedicated to it, and the organisations working on it are academic centres and nonprofits.
Kids for inclusion fits youth programmes focused on disability, integration, or access.
The convention carries the name. Programme naming in this shape has become standard across the institutional sector, which means a reader parses it as a mission on first sight rather than as an abbreviation needing explanation. That legibility is inherited, not built.
Three characters, permanently scarce, and the extension the whole sector uses.
Offers welcome.
