Summary

Osborne High School is a large public high school in Marietta, GA, serving 2,790 students in grades 9-12 as part of the Cobb County School District. The school has seen meaningful improvement in recent years, climbing from the 22nd percentile statewide in 2020-21 to the 40th percentile (rank 273 of 455) in 2025-26—its best showing in a decade. This upward trend is visible in several key areas: the graduation rate has risen from 68% to 78.9% over four years, the dropout rate has been cut by more than half, and Algebra I proficiency has nearly tripled from 11.5% to 30.2% since 2022-23. Notably, Osborne's US History proficiency (39.5%) now exceeds the state average (38.5%).

One of the most encouraging findings is how well Osborne serves specific student groups compared to similar schools statewide. African American students rank in the 64th percentile, White students in the 61st, and special education students in the 64th—all earning 3-star ratings. This suggests that when accounting for student background, the school is delivering solid educational value. However, the school faces significant challenges. Chronic absenteeism stands at 30.9%, more than double the district rate of 14.2%, and English Language Learner students rank in the 20th percentile—the weakest subgroup performance. The school also serves a student body where 100% qualify for free or reduced lunch, up sharply from 74.75% just two years ago.

The contrast with nearby Hillgrove High School, just 6.3 miles away, illustrates how profoundly economic factors correlate with outcomes: Hillgrove has a 91st percentile ranking, 96.4% graduation rate, 9.7% chronic absenteeism, and 30.28% free/reduced lunch eligibility. Yet Osborne's trajectory is clearly positive—state ranking, graduation rates, and subject proficiency are all improving, and the school retains students through graduation at a reasonable rate despite significant economic and academic hurdles. With per-student spending of $14,616, Osborne receives substantial resources, and the data suggests targeted interventions in Algebra and US History are working. The most pressing areas for continued focus remain chronic absenteeism and English Learner support.

Osborne is labeled with a less than pleasant reputation due to its location and a small number of students that misbehave. As a former student of the school, Osborne prepares student for the real world. If college is the route of choosing, the staff prepares the students. The same comment applies for those seeking technical programs, and ect. The staff is highly educated, over prepared and very diverse. They go beyond the classroom to assist the students. Osborne's class schedule allows students to graduate early as they use block systems. The AP program allows students to explore their true strengths with the help of the teachers. As a student that attended Osborne, and graduated from the SEC division 1 school, Osborne provided me with the tools to be successful in my college course work and life. Close Quote

As a current student at Osborne, I am not pleased about the things I hear about my school. People think that bad things will happen at this school when in reality the school is actually pretty quiet. The staff and the student body are the nicest people that I have met in my life. The staff treats everyone that walks through the front doors with respect. Sure, there may be students that are rowdy, but all schools have students like that. The students at Osborne are great people with big aspirations. I have to admit that before I started high school, I had my doubts about Osborne. But, as I look back at the past 3 years I've spent at this school, I realize that not only have I met good people and have made great lifelong friends, I have gained one of the best educations I have ever gotten.
