Summary

Blackwell Elementary School is a public elementary school located in Marietta, Georgia, serving grades PK-5 with a total enrollment of 583 students. The school is part of the Cobb County School District, which is ranked 54 out of 206 districts in Georgia and has a 4-star rating from SchoolDigger.

While Blackwell Elementary School has a relatively low student-teacher ratio, ranging from 11.2 to 12.3 students per teacher, its academic performance has been a concern. The school's test scores are generally lower than the Cobb County and Georgia averages across all grade levels and subjects. For example, in the 2024-2025 school year, the percentage of students proficient or better in English Language Arts ranged from 39.2% to 42% for Blackwell, compared to 43.2% to 49% for Cobb County and 34.9% to 43% for Georgia. Similarly, in Mathematics, Blackwell's proficiency rates ranged from 40.2% to 50.5%, while Cobb County's were 48.7% to 56.8% and Georgia's were 42.6% to 49%. Additionally, Blackwell Elementary School's statewide ranking has declined over the years, from a high of 289 out of 1,205 Georgia elementary schools in 2016-2017 to a ranking of 507 out of 1,238 in 2024-2025, placing the school in the bottom half of elementary schools in the state.

One factor that may be contributing to Blackwell Elementary School's lower academic performance is the high percentage of students receiving free or reduced-price lunch, which has increased from 39.4% in 2022-2023 to 55.23% in 2023-2024. This is higher than the state average and indicates a higher proportion of students from low-income families. When compared to nearby schools in the Cobb County district, such as Davis Elementary, Kincaid Elementary, and Rocky Mount Elementary, Blackwell Elementary School is underperforming, with significantly higher test scores, higher statewide rankings, and lower free and reduced lunch rates.

I am surprised that it isnt ranked higher on this site. My daughter goes to Blackwell and we LOVE it...the classes are much smaller compared to some of the other schools around, the teachers have always been nice and the school its self is always well kept, student oriented, and overall a positive experience. The ASP program is another great aspect we enjoy, the ppl in charge are always wonderful to my daughter. Close Quote
