Yes, the president of the student-elected body of mostly-powerless "school government."
The student-elected body is often called the Student Council.
Sometimes each grade level will have a class president.
Varies from school to school for the details.
Can't edit so I'll reply: This is in the United States.
That's just an elected student position that usually interfaces with the school leadership about student issues - it isn't the vice principal/principal/superintendent that run the school(s)
it’s an america thing
Other countries don't have prefects? Wikipedia seems to indicate the phenomenon is worldwide.
