Factual error: If we are to assume the film is in chronological order over the course of a single school year, then why does the football scene come after Christmas has occurred? High school football season ends well before the holiday season.

Other: In the scene where Spicoli supposedly takes a bong hit, you can see that he only inhales the air from the chamber - he takes his mouth away before the smoke gets to the top of the bong.

Continuity: When Mr. Hand shows up at Jeff's house to study history, the bong in Jeff's bedroom alternates between full of smoke and empty.

Visible crew/equipment: When Brad and Stacey pull up in front of the bowling alley and Stacey opens her car door, several crew members can be seen reflected in her car door's window.

Continuity: When Mr. Hand writes his name on the board to introduce himself to the class, he underlines it. We then cut to a shot of the class. When we see the board again, the underline is different.

Factual error: In history class, Mr. Hand tells the students that the Platt Amendment was an amendment to the U.S. Constitution passed in 1906. In fact, it was a rider attached to the Army Appropriations Act of 1901.

Continuity: You see the same shots of Sean Penn driving Forest Whitaker's car on the sidewalk and weaving between the same two cars over and over before he wrecks it.

Continuity: During the scene where Mike is trying to get Mark to ask Stacey out, the camera pans by her and her hair is pulled back on the sides in french braids with ribbons on the ends. When Mark actually approaches Stacey, we see that her hair is pulled back and clipped. No braids or ribbons are seen.
