On the day of the big game/Decathlon/callbacks, the students are excited for the festivities. Sharpay and Ryan perform their callback song ("Bop to the Top"), which at the same time happens with the basketball championship and the science decathlon, during which Taylor engineers an electronic meltdown in the decathlon and light malfunctions in the game, which forces all the students to move to the theater. Chad and Taylor explain to Troy and Gabriella that this is their only chance. Mrs. Darbus, hesitant to allow Troy and Gabriella an audition due to their lateness, has no choice but to let them audition as the auditorium fills with students ("Breaking Free"). Mrs. Darbus gives Troy and Gabriella the parts on the spot with everyone watching.
