The first phase of the group audition process is divided into three parts. A contestant coordinator gives an introductory talk reviewing the rules and particularities of the game and providing some guidelines regarding energy, volume, and timing for the applicants. Fifty Jeopardy!-style clues in fifty different categories are displayed on the screen at the front of the room and read aloud, typically live in person by Sarah Whitcomb Foss or Jimmy McGuire, the current members of the show's Clue Crew (previously, Johnny Gilbert, the show's announcer, recorded the clues and they were played as recordings). The contestant coordinators take the completed response sheets and grade them. Though some sources state that a score of 35 (70%) is passing, the contestant coordinators refuse to confirm or deny any passing score number. This is followed by a mock Jeopardy! competition. A game board is presented, and potential contestants are placed in groups of three to play the game. The emphasis is not on scoring points, or even having correct responses (though phrasing in the form of a question is required here, like the show); the contestant coordinators know that they possess the knowledge to compete on the show, as they have already passed the test, and are looking for on-the-air-compatible qualities. Prospective contestants are encouraged to display energy and use a loud, confident voice. After playing a few clues, the contestant coordinators give each potential contestant a few minutes to talk about themselves. The coordinators request that they finish by telling what they would do with any money they won on Jeopardy! After the end of the tryout, all prospective contestants who have taken the online test and the in-person test are placed into the pool and are eligible to be called to compete for the next eighteen months. Jeopardy! Brain Bus For Season 15 (1998–99), the show introduced a Winnebago recreational vehicle called the "Jeopardy! Brain Bus", measuring , which travels 12 times per year to conduct regional contestant searches throughout the United States and Canada. Those who impress the Brain Bus staff during the Brain Bus events and have passed the qualifying tests are invited to attend actual Jeopardy! auditions in California. The official Jeopardy! website used to feature a section devoted to the Brain Bus starting during Season 21 (2004–05); by Season 26 (2009–10), this section was taken down.
