How to calculate graduation year in the US education system

To calculate graduation year in the US education system, you only need two things:

  • The grade a student starts in; and
  • The school year when that grade begins.

In the United States, students typically complete 12 grades after kindergarten, and high school usually spans four years, from 9th through 12th grade.

For example, if your child starts third grade in fall 2029, there are ten school years left before graduation. That means they would graduate in the Class of 2039.

How many years is high school?

A common question is: How many years is high school?

In the US, high school lasts four years:

  • 9th grade: Freshman year;
  • 10th grade: Sophomore year;
  • 11th grade: Junior year; and
  • 12th grade: Senior year.

These four years of high school prepare students to graduate, enter college, or join the workforce. Some students may graduate earlier, while others take longer, but four years is the standard length of time.

For a more comprehensive overview, the "Guide to School Years and Levels of Education in the United States" provides an overview of the entire American education system, from early childhood to high school graduation.

Understanding high school years and grade levels

The US education system is divided into stages:

  • Primary education (elementary school);
  • Secondary education (middle school and high school); and
  • Post-secondary education (college and beyond).

Students earn credits based on the courses they take, measured in Carnegie units. Each state sets its own rules for graduation. However, most require between 20 and 24 credits in subjects such as math, English, science, and history.
