Blackwell Elementary School

Q: Is Blackwell Elementary School a good school?

Blackwell Elementary School ranks 506 th of 1248 Georgia elementary schools. SchoolDigger rates this school 3 stars out of 5.

Summary:

Blackwell Elementary School is a public elementary school in Marietta, Georgia, serving 632 students in grades PK-5 as part of the Cobb County School District. While the district is ranked 52 out of 203 in Georgia, Blackwell Elementary has seen fluctuating performance over the past decade, with its statewide ranking ranging from 289 to 629 out of around 1,200 Georgia elementary schools.

Blackwell Elementary's test scores on the Milestones Assessment are generally lower than the Cobb County and Georgia averages across all grade levels and subject areas. For example, in 2023-2024, the school's 3rd grade English Language Arts proficiency rate was 35.6%, compared to 48.2% for Cobb County and 38.4% for Georgia. Additionally, Blackwell has a relatively high percentage of students receiving free or reduced-price lunch, ranging from 39.4% to 41.31% in recent years, which is higher than the state average. The school's per-student spending has increased from $9,936 in 2016-2017 to $11,176 in 2018-2019, but it remains lower than some of the nearby higher-performing schools, such as Davis Elementary, Kincaid Elementary, and Rocky Mount Elementary.

Despite having a relatively low student-teacher ratio, ranging from 11.8 to 12.3 in recent years, Blackwell Elementary's performance lags behind many of the nearby schools in the Cobb County district. The high percentage of economically disadvantaged students and the school's inconsistent performance over time suggest that Blackwell Elementary may benefit from targeted interventions, professional development for teachers, and additional resources to support student learning and improve academic outcomes.

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

About Students eligible for discounted/free lunch:

The National School Lunch Program (NSLP) provides low-cost or free meals to students in U.S. public and nonprofit private schools based on household income. Those with incomes below 130% of the poverty line receive free lunch, while those between 130% and 185% qualify for reduced-price lunch. The percentage of students receiving free or reduced-price lunch serves as a marker for poverty, as it reflects the socioeconomic status of families in a given school or district. A higher FRPL rate typically indicates a higher concentration of low-income families, suggesting that the school or district may face additional challenges in providing adequate resources and support for student success.

About Student-Teacher Ratio

Student/teacher ratio is calculated by dividing the total number of students by the total number of full-time equivalent teachers. Please note that a smaller student/teacher ratio does not necessarily translate to smaller class size. In some instances, schools hire teachers part time, and some teachers are hired for specialized instruction with very small class sizes. These and other factors contribute to the student/teacher ratio. Note: For private schools, Student/teacher ratio may not include Pre-Kindergarten.
