Continuity mistake: When Cat, Beck, Robbie, Jade and Andre are telling Tori about why they faked the Ping Pong team, it shows a flash back of two years ago when Tori hadn't started at Hollywood Arts yet. But in the background of the hall when they are asking for Sikowitz to help them, Tori's locker is there - how can her locker be there when she hasn't even started at the school yet?
Plot hole: In this episode all the students say Hollywood Arts has never had a prom before. But in the first episode, 'Pilot', Rex says to Cat after she runs out to tell Tori, Robbie, Andre and him that Sikowitz wants them to come back into the classroom, "Just like you wanted a date to the prom last year."
Continuity mistake: Trina throws Tori's laptop onto the couch next to them. About a minute later, Jade comes in to Tori and Trina's house, and sits on that couch, where the laptop originally was. The laptop is missing, and nobody could've moved it, because nobody was near the couch in between the two events.
Continuity mistake: In "Survival of the Hottest" or "Stuck In a RV", the scene after Cat runs to go to the bathroom you will see that Jade & Beck enter the RV and Jade has her sunglasses on top of her head. The scene then goes to Trina & Tori, back to Beck & Jade, Trina & Tori again, the back to Jade & Beck, but Jade's sunglasses vanish. Then it goes back to Trina & Tori, then Beck & Jade and the sunglasses are on her head again.
Plot hole: Some episodes act as though Drake and Josh was real and some act as if it is a T.V. show. In the episode with the new principal, Helen from Drake and Josh is the same character as she was in Drake and Josh and becomes Hollywood Arts' new principal. But, in the episode when Trina's play-scene was sabotaged, Cat and Tori refer to Drake and Josh as a television show.
Continuity mistake: When the gang watches an advanced copy of "The Wood", and Jade watches the fake phone call between Beck and Tori, the background and scene changes from Beck at School, in the day, to Tori at Home, at night (viewable through windows) This isn't noticed by Jade.
Continuity mistake: When the girl accidentally throws water on Jade, her face and hair are wet, but then when it goes back to the girl and then to Jade again, her face and hair are dry for a few shots, then when Jade goes inside the school in the hallway and Andre stops her, her hair and face are wet again.
