Clark Kent attended Smallville High from 2001 to 2005 with his close friends Pete Ross, Chloe Sullivan and Lana Lang. Clark once ran for Class President for the 2002/2003 school year, but lost the election soundly to fellow student Paul Chan, who won despite being injured and absent. Chloe's cousin Lois Lane briefly attended as a senior student in 2004 to gather study points for entering Metropolis University.
The Smallville High marquee was struck by a meteor in the May 2005 meteor shower that struck Smallville.

- Smallville Scarecrow
- Main Article: Scarecrow
The Scarecrow is a traditional Homecoming week prank in which Smallville High senior football players choose a male freshman which they take into the cornfields, strip him down to his underwear, paint a red S on his chest, and hang him on a post as a scarecrow. Jeremy Creek and Clark Kent were both chosen as Scarecrows.
In an attempt to send a message to Clark a degenerated clone of Lex Luthor kidnaps Lois Lane and deliberately strings her up as a scarecrow with a red 'S' painted on her shirt in the exact same field the original Lex Luthor had found and rescued Clark.
- Dunk Tank
Early each year, a chosen student sits above a dunk tank after classes where other students may attempt to dunk him/her by hitting the target with a football passed out by a member of the football team. Lana Lang and Clark Kent have both been in the dunk tank (Facade). Clark was about to dunk Lana, and Lois managed to dunk Clark.
