When Elizabeth and Lynn go out to eat, the lipstick on Elizabeth's lips changes shades in several scenes; close ups show her wearing a dark red, while other shots show a light pink.
When Elizabeth's roommate rips the mirror off Halabi's Taurus, he throws it and it slides under the Volvo wagon across the lot. Later the mirror is seen in the middle of the lane, no where near where it was thrown earlier.
When Halsey draws a circle around the celebrity's breasts in the magazine, she marks it with a star. In the next shot of the magazine, the star has disappeared, and now all three photos of breasts have been circled.
When Elizabeth is watching television on New Year's Eve and her roommate is talking to her, she dips a whole corn dog into the mustard. In the next shot, the corn dog is eaten almost to the middle.
When Amy Squirrel screeches up to the field trip to confront Elizabeth, the first view of her car is from the front driver's side, and it's blue. The next cut is a quick view from the back, and the car is red. Then the view flips back to the front driver's side, and it's blue again.
Elizabeth's car has no front license plate, which is mandatory in Illinois.
When Ms. Squirrel eats the apple covered in poison ivy, she rubs it on her face which results in a rash where she rubbed it. However she would have also had this rash on her lips and mouth, but she does not.
Scott tells Elizabeth that his Jaeger-LeCoultre watch was made by his maternal grandfather, and insinuates his mother's family continues to own the firm. Roger LeCoultre (Scott's "grandfather") sold the family's holding company in 1969, after a 17 year period in which the marketing director of Vacheron Constantin was the CEO of Jaeger-LeCoultre. While LeCoultre remained Chairman of the holding company, it was the first time a LeCoultre was not in charge of LeCoultre & Cie. Unlike his father, grandfather, and great-grandfather, LeCoultre was not a watchmaker, so he could not have made his "grandson's" watch. Jaeger-LeCoultre has been owned by Swiss luxury group Richemont since 2000.
The same exact shot of a student in Ms Squirrel's class is shown at two different times in the movie. However, this is used as a comical shot to show how this student feels about Ms. Squirrel's class.
The drug detecting dog would not have been fooled by the drawer's false bottom.
It wasn't, it was the officers who were fooled by it.

Elizabeth is seen collecting cans from the school in order to pay for breast implants. Illinois does not have existing container deposit laws, however, Elizabeth could have earned money through selling the cans for their aluminum value to a recycling center.
At the beginning of the film, Elizabeth Halsey speeds backwards violently past a school bus and makes a sharp turn leaving visible tire marks on the ground. You can see tire marks on the ground before she creates them and were probably created in previous takes.
When Elizabeth is checking her online bank account. The URL reads "/online/banking/account/", but has no domain.
When Amy gives Scott the book in the gift bag, he takes it out and looks at the cover, which the viewers don't see, but one can tell that he's holding the softcover upside down because the viewers see the 'first' page. This is actually the last page of a book and appears to be a full-page index.
Guidance counselors are not "promotions" for teachers. They are paid on the same pay scale and are considered certified staff just like teachers. Elizabeth would have had a counseling endorsement on her teaching license to have taken that job.
Scott's last name would be "Petruzzello" in real life, not "Delacorte", his "mother" Irène LeCoultre having married a man named Angelo Petruzzello.
Towards the end of the movie, Lynn says, "Hey, Elizabeth", but her mouth doesn't move.
Early in the film, the buses shown around the school are marked "Boone County Schools," but later in the film it is stated that the school is in Cook County.
The movie is set in Chicago, but Period 5 performs at the Cowboy Palace Saloon. This bar is located in Chatsworth, California (where the movie was filmed), not Chicago.
After Amy is transferred out of the district at the end of the movie (due to being framed for Elizabeth's drug abuse), Scott offers Elizabeth a real relationship, but Elizabeth declines and instead hooks up with Russell. However, neither Scott nor Amy are ever seen or mentioned again beyond this scene, so whether or not Scott and Amy rekindle their budding romance goes completely unexplained.
At the very end of the movie, right before the end credits roll, it is revealed that Elizabeth has been promoted to the school's guidance counselor, but it is never mentioned what she did to earn this promotion.
Grading the students' papers, Miss Halsey marks Tristan's essay test as "Stupid point Misspelled" circling the word "layer" (which is lawyer without a W). However, she misses the more obviously misspelled word "lawer" (lawyer without a Y), and overlooks the use of "whose" instead of "who's".
(at around 47 mins) Elizabeth orders her class to open their copies of "To Kill a Mockingbird" to page 1, and asks them why Jem cries when the hole in the tree is filled with cement. That scene doesn't occur until chapter 7.
On the field trip not one child is sitting in the usually coveted back row.
