Other mistake: When the Ashleys are first shown playing jacks, Ashley T's nose seems to be missing; then it reappears three shots later.
Schoolworld - S4-E21
Continuity mistake: The door to Miss Grotke's classroom opens inward throughout the episode. However, when SAL mimics Principal Prickly and tells all the teachers to report to his office, Miss Grotke leaves the classroom, and the door now opens outward. Then, when the kids look outside the classroom, the door has completely vanished.
Mama's Girl - S2-E14
Continuity mistake: When Spinelli goes to sit with the other kids at lunch, there is a kid in a red shirt sitting behind T.J, eating his lunch with his spoon. When Spinelli slaps her tray away from her, this kid's right arm is now suddenly resting next to his tray, and his spoon disappears from his hand. He then changes the position of his body and hands, and in the next shot, he's back to his original position.
Continuity mistake: In the introduction, when TJ pulls the ball off Gus, Gus is covered in gum. When they are walking into the school, the gum has disappeared.
Continuity mistake: When TJ is making the morning announcements, the Ashley who wears green is sitting behind Spinelli. When he says there will be dessert after lunch, the desk behind Spinelli is empty.
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: When Mikey's music teacher gets engaged to the Spanish guy, her ring disappears between shots.
Continuity mistake: When The Library Kid speaks for the first time, you see a shot of the gang, T.J's hat and hair colour are mixed up.
Continuity mistake: When TJ's friends climb 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; then he reappears a moment later.
Character mistake: When Mikey looks at the Picture Day schedule, he points out that 4th grade is going last. However, the schedule says they are after 3rd grade and before 5th grade, actually making them fifth. The faculty is actually listed last on the schedule.
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.
Plot hole: Whenever Gretchin calls Mikey up to the stand to explain what he saw, he says that he had followed Spinelli and Randall to the wooden fence, where he Saw Randall on his knees in front of Spinelli, begging for forgiveness, then Mikey began running to the other side to stop Spinelli from pummeling Randall with the "rock" but didn't make it in time. We then later find out that Spinelli had actually rescued Ms. Finster's cat out of a tree and Randall hit himself with the rock out of spite. But it is impossible that Spinelli could have given up on hurting Randall, climbed up a tree, rescued a cat, climbed down, handed the cat back to Ms. Finster, gotten praise from Ms. Finster, then have Randall attempt to pick up a big rock, then get a smaller one and hit himself with it in under 3 seconds (the duration of how long Mikey ran before he heard Randall's scream).
The New Kid - S1-E2
Continuity mistake: In the beginning, as Gus' dad walks away, the A/C duct goes way down the hallway, and one side is halfway in one tile and the other side is halfway on another tile. When Gus is talking, the duct is much shorter, and the whole duct is contained in one tile.
The New Kid - S1-E2
Other mistake: At the start when the gang change the time on the clock in the classroom, it wouldn't control the main school clock, plus in every other episode the clock has been operated by The Box on the side of the school, as shown in " The spy who came into the playground".
Continuity mistake: Throughout the scene where Spinelli shows off her jump roping skills, the two Ashleys swinging the rope quite awkwardly and choppily go from a normal to a surprised expression every second or so.
The New Kid - S1-E2
Continuity mistake: Near the beginning, after King Bob declares Gus as The New Kid, the kids are cheering and TJ and friends have disappeared from the shot. Then Gus looks down in front of him and the guys are right there in front of him.
The New Kid - S1-E2
Continuity mistake: In the beginning, as Gus' dad walks away, there is a sign on the door to the right that says "Boys." I would assume this is a restroom. Then, two shots later, it shows Gus from his front and in place of that sign is a window.
The New Kid - S1-E2
Continuity mistake: When Gus' dad introduces himself, he says he's in the USMC (US Marine Corps). In the rest of the episodes, he's in the Army.
The New Kid - S1-E2
Continuity mistake: When Spinelli says, "Roger already, let's get this show on the road", there's a puffy cloud under "Good" in "Good Morning Gus". When Gus is in the bus and notices the billboard, the cloud is pushed in on the upper left part of it.
Audio problem: After "Peanut Butter Kid" retrieves the baseball Vince hit (presumably all the way to China) Spinelli screams rather loudly. However her lips don't move when she does.
