as "Pre-Test" events, attendees are given a 10-question version of the qualifying test; the number of attendees at this event may not exceed 1,000. Attendees who pass the test are invited back to attempt the full 50-question qualifier the next day. People who have passed the 50-question test move on to a final interview, during which show producers determine whether the contestant is someone by whom the TV audiences would be impressed. In addition to the "Pre-Test" events conducted there, Brain Bus searches also feature an event where individuals not wishing to compete for a chance to appear on Jeopardy! can play a "mock version" of the quiz show's game hosted by one or more members of the "Clue Crew", the program's team of roving correspondents; instead of cash, the attendees of this event play for various prizes, such as T-shirts, hats, mugs, water bottles, pens, and other merchandise related to the show. During the "mock Jeopardy!" events, the hosting Clue Crew members will occasionally interact with fans in attendance. Episodes featuring children as contestants Tryouts for Kids Week, Holiday Kids Week, and Back to School Week were slightly different in that the mock Jeopardy! game is played before the thirty-question test is given. During the mock game, coordinators sometimes opened up triple stumper questions to the other potential contestants. Potential contestants were called or notified by the station on which Jeopardy! airs in that particular market. Fifteen children who were between ten and twelve years old were chosen for each filming, along with one alternate. Waiting period The mandatory waiting period after taking the online contestant exam is one year, although this may be adjusted by the show's production team based on the test schedule. Prospective contestants who have completed an in-person test and interview remain in the contestant pool for 18 months, only after the expiration of which may they take the online test again and attend another in-person audition. Auditions in the Art Fleming era Tryouts for the original version were conducted somewhat differently. In a classroom-type arrangement, potential contestants wrote their questions to the answers held up by the contestant coordinator, who used cards which had previously actually been used on the show. While the exams were being scored, the staff explained that on any given day, the contestants who actually appear all scored the same number (or very nearly the same number) on this tryout.
