School Overview

Kell High School sits in the northern reaches of Marietta, in the kind of suburban Cobb County neighborhood where families tend to put down roots and stay. Academically, it punches well above average across the board — strong in English, math, and especially science — making it a solid choice for families who want a well-rounded public school without the pressure of a magnet or specialized program. The surrounding area has that classic North Atlanta suburban feel: good restaurants, easy highway access, and a community that takes school spirit and academic achievement about equally seriously.
