The Judicator's Test in Wandering Ronin is a series of questions to determine how well a player knows the Rulebook. Once a player scores high enough on the test, he/she is allowed to carry the title of Judicator, which is an official judge on the field of combat and Trial of Arms. There are 10 different versions of the test. A player is allowed to take 5 of them, one at a time, during each of the four events regularly scheduled during the Wandering Ronin calendar year. If the player fails all the tests, he/she must wait until the next Rulebook Committee completes its revisions before aforementioned individual may attempt to pass the next set of tests, which will be re-written to accord any new rules put into place.

Various officers must also pass this test to varying degrees of success before they are allowed to either claim the title or hold office.
