Continuity mistake: During the speech which the basketball team gives to Troy, we have shots altering between Troy and Chad. When we see Chad, the two guys behind him are standing basically next to each other. When the scene cuts to Troy, the same two guys are now much farther apart (the right one of the two would be blocked by Troy if they stood as close together as in the previous shot).

Continuity mistake: When Troy tells Chad that he wants to catch up on some homework and then heads to the audition, he's wearing jeans with thick decorative white stitching above his right pocket (viewer's left). However, when Troy raises his hand and volunteers to sing with Gabriella, he is wearing different jeans - the decorative stitching above the pocket is gone.
Chad Danforth: Have you ever seen Michael Crawford on a cereal box?
Troy Bolton: Who's Michael Crawford?
Chad Danforth: Exactly my point! He was the Phantom of the Opera on Broadway. Now, my mom, she's seen that musical 27 times and she put Michael Crawford's picture in our refrigerator. Not on it, in it. So, my point is if you play basketball, you're gonna end up on a cereal box. If you sing in musicals, you're gonna end up in my mom's refrigerator.
Troy Bolton: Why would she put his picture in her refrigerator?
Chad Danforth: One of her crazy diet ideas! Look, I don't have time to understand the female mind, Troy!
