I would describe this as "leap-frogging."

"Leap-frog" is a childhood game.

1. A boys' game in which one player places his hands upon the bent back or shoulders of another and leaps or vaults over him. Also, a jump or leap of this description. (OED)

Merriam-Webster has a better example of this metaphorical usage:

Skipping his last two years of high school, he leapfrogged his classmates and went to college.
