Heritage Oak's Middle School Extended Day program allows for students to arrive prior to 7:00am and stay at school beyond 6:00pm. In order to allow for students to have quality family time in the evening, the students in Extended Day work to complete their homework prior to leaving school.

In addition to Extended Day, multiple after-school activities are available to broaden the interests and skills of Middle School students. Athletes participate in Football, Volleyball, Basketball, and Soccer as part of the Tri-way Athletic League. An after-school competitive Debate Team is available as well as a comprehensive performing arts program which culminates in a Broadway-style Musical Theatre Production each year.
