I could not be happier having my son at Kell and look forward to my daughter attending in a year. We are so fortunate to have this gem of a school in Cobb County. The administration, teachers, extra curricular opportunities and overall community are fantastic. The communication is excellent. They follow through on what they say they are going to do. Kell provides our students the tools and experiences they need to be successful and achieve college readiness in a very safe and nurturing environment. I have been particularly impressed with the (marching) band program. Close Quote

Great change to the school this year! Dr. Giles has brought back school spirit, community, and pride to the school. Teachers and students feel valued again! The new LASSO structure is awesome and has helped so many students academically already and is an incentive for all students. Proud to live here and have my students go there. Don't believe any previous bad comments about the school. It has all changed now! 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.
