How Many Weeks In A School Year?

The exact number of weeks in a year that the fall semester covers varies due to lessons only being held a few days out of another week (and school closures).

For example, a school district in South Florida has a 20/21 school year that runs from August 19th to June 9th, covering 43 weeks of the 52 weeks in a complete year. However, due to vacations and teacher planning days, four full weeks and a total of 31 days closed. In all, the schools are open for 39 weeks, for a total of 180 instructional days.

What Is The Number Of School Days In A School Year?

The National Center for Education Statistics (NCES) estimates that there are around 160 to 185 school days in a year, including an average of 175-180 days. Again, this number varies by state, district, and so on. Some institutions may also satisfy a minimum amount of teaching hours every school term rather than days.

Using the South Florida school as an example, the school year ran from August 19th, 2020 to June 9th, 2021. The school is closed on 31 of those days, leaving 180 teaching days.

Houston, Texas, on the other hand, has a school term that lasts 40 weeks and is open for 36 of them. It runs from September 8th, 2020 to June 11th, 2020, for a total of 199 weekdays. After 28 days of holidays and teacher preparation, the Houston school term is just 171 days of instructional time.
