 Welcome Freshmen was filmed at Nickelodeon Studios in Orlando, Florida. The earlier episodes of the series consisted of comedy sketches that loosely followed a theme. Some of the comedy routines involved a tortoise teaching children about safety, a documentarian who talks about past generations of freshmen, the principal imagining himself as a stand-up comedian, and a student who, though his appearance was occasional, provided not only a good example of how not to behave, but also a good example of flatulence. In the later episodes, this format was abandoned and an episode would follow a plot in its entirety.
