How Many Weeks Are There in a School Year?

The schedule for public schools lies with each particular school district of which it is a part; as such, the total number of weeks in a school year can vary considerably. The number of weeks in a school year for a private school is set by the school in question.

When all is considered, the total number of school days throughout the United States on a basic school schedule averages 180, spread over 40 weeks throughout the year. This number is also applied to some year-round schools, which allocate longer breaks throughout the traditional September to June schedule, but a shorter summer break and as such, students attending year-round schools do have classes in the summer.
