Cognia Review

Cobb families know the Cobb County School District has a reputation for excellence, as Cobb’s students consistently perform better than their peers. You could live anywhere, yet over 200,000 parents choose to raise their children in Cobb. You know that a Cobb education gives your children a competitive advantage for scholarships, college, future employment, and life. 

Once again, Cobb families can feel even more confident their students are receiving a high-quality education following the most recent accreditation review by Cognia, one of Cobb’s accrediting agencies and one of the largest in the world. 

After recently completing an Accreditation Engagement Review, which took almost one year to complete, every school in Cobb County has been accredited for an additional six years. 

Our History

Garrison Mill Elementary School opened its doors to neighboring children in August of 1984.  The story doesn't start there.  It begins over 100 years ago when the Garrison family moved to Cobb County.  Thomas Wesley Garrison, Sr. and his wife, Malinda, settled at the headquarters of Willeo Creek before the Civil War.  They owned a large plantation called "Mill Hill" because they operated a sawmill, a corn-grinding mill, and a cotton gin.

Mr. Garrison donated 4 1/2 acres to the trustees of Wesley Chapel United Methodist Church on Sandy Plains Road and assisted with the first church construction in 1879. The Garrisons were concerned with the education of not only their children but those in neighboring areas. With his help, a school was completed in 1880.  An historical marker stands today at this spot.

Garrison Mill Elementary School is currently home to more than 700 students and is named for all generations of the Garrison family presently living in this area and for Thomas Wesley Garrison who saw a need for education so long ago in his mill on the hill.
