Cobb Horizon High School, Atlanta GA

Original Research by School Decision on Cobb Horizon High School

Cobb Horizon High School is a regular public school serving grades six through twelve in southeast Atlanta, positioned in a mixed residential and commercial area near The Exchange development corridor. The school enrolls a small to mid-sized population with substantial diversity: about two in five students are Black, nearly a third are Hispanic, about one in four are white, and a small share are Asian. About one in four students qualify for free or reduced-price lunch.

The school's academic profile shows persistent challenges across tested subjects. On state end-of-grade assessments, proficiency in English language arts sits below half of students across tested grades, and mathematics proficiency is notably lower, with seventh-grade math proficiency around one in seven students and eighth-grade math around one in four. Science proficiency at eighth grade is particularly low. Social studies proficiency is also below one in five. These results place the school in the bottom quartile for overall proficiency compared to other schools in Cobb County. State testing data at the high school level (grades nine through twelve) was not available in the data provided.

A parent may want to look into this further with the school: whether the school has targeted interventions underway in math and science, whether there have been staffing changes, and what the school's graduation rate and post-secondary pathway outcomes look like, since high school results are not reflected in the state testing data shown here.

The school draws from Atlanta, a major regional employment hub with headquarters for several Fortune companies, a growing tech sector, and anchors including Emory, Georgia Tech, and the CDC. The Atlanta BeltLine trail network and downtown redevelopment efforts have shifted the city's character in recent years. Housing in the school's zip code shows median values and rents slightly above the Georgia state average, with affordability indicators suggesting modest monthly mortgage and rental costs relative to area income. The immediate area is car-dependent, though walkability varies across Atlanta's neighborhoods.

Cobb Horizon's student body reflects the city's demographic composition and lower-income representation. Without visibility into program offerings, staffing levels, or school-level operational changes, a prospective family would benefit from direct conversation with the school about its academic support structure, any recent initiatives in response to proficiency trends, and what educational pathways—whether career and technical education, dual-credit coursework, or college-preparatory tracks—are available to students across its grade range.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
