Summary

Pebblebrook High School in Mableton, GA, is a large public high school serving 2,574 students in grades 9-12 within the Cobb County School District. Over the past decade, the school has climbed from the 22nd to the 59th percentile in statewide rankings, moving from a 1-star to a 3-star rating—a steady improvement that stands out among nearby schools.

Pebblebrook’s most notable strength is its performance with student groups that often face the biggest challenges. The school ranks in the 76th percentile statewide for African American students, the 75th percentile for English Language Learners, and the 70th percentile for Special Education students—all earning 4-star ratings. In Biology, proficiency jumped from 32.7% to 45.3% in one year, nearly matching the state average and far outpacing Osborne High School, which saw a slight decline. U.S. History proficiency (48.9%) exceeds the state average by more than 10 points and is well ahead of Westlake High School (27.7%) and Lithia Springs Comprehensive High School (17.5%). The school also spends less per student ($14,156) than schools like Benjamin E. Mays High School ($26,366) while achieving stronger results.

Despite these academic gains, Pebblebrook faces real challenges with student engagement. Chronic absenteeism sits at 34.3%—more than double the district average of 14.2%—and the graduation rate of 75.7% trails the district’s 89.2%. Compared to South Cobb High School, just 2.5 miles away, Pebblebrook ranks slightly higher academically but has a lower graduation rate (75.7% vs. 87.9%). Nearly all students (96.5%) now qualify for free or reduced lunch, up from 70.4% two years ago, yet the school has continued to improve—a sign of resilience and effective instruction under challenging circumstances.
