Tr3 Trends: Student and Teacher School Year

See all posts

August 2013

Welcome to Tr3 Trends, NCTQ's monthly newsletter designed just for school district officials (subscribe here).  Each month we use data from NCTQ's Tr3 database to highlight the latest trends in school district policies and collective bargaining agreements nationwide.  Tr3 contains teacher policies from 114 school districts, including the 50 largest districts, the largest district in each state, Broad Prize winners, Gates investment districts and members of the Council of the Great City Schools.  Teacher policies from all 50 states are also included. 

With the start of a new school year upon us, we thought we'd take a look at the 2013-14 calendars in the 114 school districts we track.  Here's what we found:

The modal student school year length is 180 days, with 16 percent of our 114 districts  scheduling a longer year and 50 percent a shorter year.

The average number of days in students' school year is scheduled to be 178 days in 2013-2014.  That's a one day decrease from the 2012-2013 school year.

For the second year in a row, of all Tr3 districts, Tulsa has the shortest student year at 168 days. Baltimore County has the longest year at 186 days.

In a large majority of districts, the length of the student school year remained unchanged.  Only 12 percent increased their year and 21 percent decreased their year.

The table below lists the districts that changed the number of days their students are in class from last year.


On average, teachers will spend approximately 5% (or 9 days) of their 2013-14 work year on-site without students. 

Teacher time without students commonly occurs both in full days and in partial days when students are released early.  When calculating teacher time without students we include both full and partial days. For example, we've calculated that teachers in Guilford County, North Carolina are on-site a total 17 days without students.  Fourteen of those days are full days that teachers work but students don't come to school.  The remaining three days come from six days where students are in school for only half the day.

Students' summer breaks ranged from 7 to 14 weeks, and most (77%) had breaks that were 10 to 11 weeks long.

Indianapolis students have the shortest summer break at 55 days--just under 8 weeks.  At 98 days (14 weeks), students in Tulsa have the longest summer break and are closely followed by DeSoto County, Mississippi (97 days) and Sioux Falls, South Dakota (96 days).

Two districts--Nashville and Indianapolis--have one-week intercessions in the fall and spring for students in need of remediation.  While both districts have some of the shortest summer vacations (Indianapolis at 55 days and Metropolitan Nashville at 69 days), students who do not attend intercession have an additional two weeks off during the school year.

20 percent of districts delay the first day of school until after Labor Day.

Several districts in major cities, including Boston, Seattle and San Diego all have start dates after Labor Day.  New York City and Philadelphia, however, clock in with the latest start date, September 9, of all Tr3 districts.  On the other end of the spectrum, students in Nashville start over a month earlier, on August 1, and are the first students of any Tr3 district to begin their school year.
