The New Kid - S1-E2
Continuity mistake: In the beginning, after the kids have gone to recess, Vince starts talking to TJ about Gus. The number of bricks between the windows on the wall behind them and the bricks' position changes four times.
Continuity mistake: Across the show, the number of kids in a class/what kids are in which class varies. For example, in "The Great Can Drive", the Ashleys are in Ms. Furley's class. However, in almost every other episode besides this one, the Ashleys are all in Ms. Grotke's class, and the exception are a couple of episodes in which 2 Ashleys are in Ms. Grotke's class, and the other 2 Ashleys are in another class (which is not specified by name), making a serious consistency error.

The New Kid - S1-E2
Continuity mistake: In the beginning, right as Mrs. Grotke asks for Gus to describe his "personal journey", there is a short kid with a white t-shirt and dirty blonde hair, with the globe behind his head. As the kid asks if they can go to recess now, the globe has moved way to the left.
Continuity mistake: The kid who says "Dumb 4th graders..." IS a 4th grader. Watch the beginning of "The New Kid" and you can see him in Mrs. Grotke's class.
Continuity mistake: Throughout the scene where Spinelli shows off her jump roping skills, the two Ashley's swinging the rope quite awkwardly and choppily go from a normal to a surprised expression every second or so.
Continuity mistake: When TJ is in The Box, he lays down and puts his head on his baseball glove. Then when he gets up, he doesn't pick it up, but it's nowhere to be seen. Then a couple of shots later, it's back, and it's on the other end.

After TJ says that the kids can refuse to answer a teacher, the same kid is suddenly sitting in the second row so he can slap hands with someone in the first row.
Continuity mistake: When TJ's friends climb on on the jungle gym to try and take TJ's place, we see that Gretchen is the last one up and there is no one on the bars behind her. But in the next long shot, Mikey is right behind her. Then when it shows a close up of them, Mikey is gone again.
Continuity mistake: In the beginning, the kids are outside the school, and Mikey says, "Last?" But the sign says the fourth graders are right after the 3rd graders, right where they should be.
