When the girls are following George Martín by the fire at the beach party, the third girl in line appears again as the sixth girl in line, although in the later shot she appears with more clothing than in the earlier shot. This is because the scene is cut up into several shots in editing and shown in the wrong order. The second shot featuring this girl is the beginning and the first shot is the end of the same take.
Crew or equipment visible
During the scene where Hightower (Bubba Smith) flips the police car in training (at the 1 hour 10 minute mark) as the camera pans down to the ground, off to the far right, for a brief second you can see a large bare arm of what appears to be a crew member (hidden behind the car) that aided in flipping over the car.
Incorrectly regarded as goofs
When Captain Reed and Mahoney are in the interrogation room at the police station, Captain Reed tells Mahoney that the duration of the police academy is 14 weeks long. When Mahoney is at the academy Commandant Lassard tells him the academy training is 24 weeks long. However, Lassard gets the length of time wrong repeatedly throughout the film, even having to be reminded of it when inspecting the new cadets.
When Captain Harris tells the cadets that Blankes and Copeland will be the cadets in charge, he says ¨Blankes and Dopeland.¨ This is probably deliberate as Captain Harris doesn't respect Copeland as much as Blankes, as indicated by Harris's reaction to Copeland attempting to shake Harris's hand earlier.
