how old are high schoolers

High school students are typically between the ages of 14 and 18 years old. This age range generally corresponds to grades 9 through 12, with 9th graders (freshmen) usually around 14 years old and 12th graders (seniors) around 17 to 18 years old. Some variations occur depending on when students started school or if they skipped or repeated a grade, but these ages are the typical norms in the United States.
