Surprisingly, no. At least in highschool and below.
Highschool started off with Scratch just for kids to learn the fundamentals of programming and logic. From there, we moved up to JS and finally Java in grade eleven.
Grade 12 computer science classes consisted of whatever language you wanted to use (since most kids already had a fave) and you basically just built a few projects (and a large project) over the course of a semester.
Computer engineering classes were a little lower level, involving some assembly and C, but in the early months we mainly used Arduino.
In my uni classes, we've done Python for the first year classes. Second year bumped back up to Java, third year involves some C-like languages, Go, Scala, Scheme/Lisp for different paradigms.
