Class of 56

Vice Principal Strickland speaks to the Hill Valley High School graduating class of 1956.

1956A was an ABC timeline and a year in the 20th century. The altered timeline it belonged to was created when an elderly Biff Tannen traveled from 2015 to give his younger self from 1955 a sports almanac to make himself rich.


  • Biff didn't graduate with the rest of his class, as he was expelled for trying to bribe Vice Principal Stanford S. Strickland the previous year.
  • Biff begins pranking Strickland, which gets worse as the years go on.

Alternate timeline of events

For years in this timeline after 1955, see the Hell Valley timeline.

  • Date unknown:
    • While Vice Principal Strickland is giving his speech, Match, Skinhead, and 3-D climb above the stage, releasing a banner that reads "Life's a Beach. SEA You Next Year!", while dumping a bucket of water on Strickland's head.
