Trivia / Head of the Class

  • The Danza: Billy Connolly as Billy MacGregor.
  • Dawson Casting: Dan Schneider was born in 1966. You do the math.
    • Tony O'Dell was born in 1960. Dan Frischman, playing one of the students, was born in 1959, making him 27 years old when the series began.
      • Basically most of the cast other than Tannis Vallely (Janice), who was the first one to leave (she was really smart).
    • TV Guide commented on this when they featured the finale on its cover, saying it was nice to see a bunch of 30-year-olds graduate.
  • Permanent Placeholder: Mr. Moore, a substitute teacher, becomes the permanent teacher of the advanced history class during the Mid-Season Twist.
  • Written by Cast Member: "Will The Real Arvid Engen Please Stand Up?" was the first writing credit for Messrs. Robbins and Schneider. It would definitely not be the last.
