Richter's scale of cultures

Richter's scale of cultures was a method of describing cultural achievement. 
Prior to learning their true nature in 2267, Federation experts rated the Organians at approximately class D minus on this scale; presumably, this corresponded to an agrarian culture with hand- or animal-powered machinery. ()

===Apocrypha===
In the TOS novel , Doctor Alonzo Richter invented the Richter scale of culture in the early 2200s to monitor a civilization's progress.
