Frequently Asked Questions

What is Cobb Horizon High School?

Cobb Horizon High School is a new school in the Cobb County School District, having opened during the 2018-2019 school year after the merger of Oakwood Digital Academy and the Cobb Performance Learning Center, the district's two alternative high schools.  Cobb Horizon High School is a non-punitive alternative school that is available to Cobb County high school students.

Students may apply to attend Cobb Horizon instead of their designated Cobb County high school if they are in need of a different path to obtain enough credits to earn a high school diploma. If accepted into our program, students are enrolled in one of our three sessions, each of which meet Monday through Thursday. Students do not attend school on Fridays.

Our students have chosen to attend our program due to various reasons such as a need to improve their academic performance, having work or family commitments that conflict with the hours of their high school, social reasons, transferring from a school out of state and needing additional credits in order to graduate, or due to other reasons.

Some students, especially those who are new to Georgia, may be assigned to attend Cobb Horizon instead of their local high school since they may be able to earn more credits each semester at Cobb Horizon compared to their local high school.

Our instructional format differs from that of a typical high school. Student coursework is primarily completed through various online platforms with teachers available to answer student questions and assist them with their online assignments.

Students are able to work at their own pace and, in many cases, accelerate their learning. Students work in a small classroom setting and receive one-on-one attention. Although most coursework is completed online, students are also expected to complete offline assignments and participate in small group instruction. All of our teachers are Georgia certificated and hold degrees in their respective fields.

Our school's enrollment is usually a few hundred students with a maximum of 450.
