*In late August, the marking periods for our high schools were adjusted. On September 10, the calendar was revised and high school marking periods are no longer listed. For information about high school marking periods, please click here.
On March 14, 2018, the Board of Education approved the OUSD school year calendar shift, meaning that OUSD now begins the school year earlier in August and ends the school year in late May instead of June.
To learn more about the rationale and support for this 2018 decision, please visit ousd.org/newfirstday.
