During the 2003-2004 school year, the City Schools of Decatur Board of Education engaged in an extensive strategic planning process for the school system that involved the entire city of Decatur community. The City Schools of Decatur Strategic Plan was developed and adopted in the spring of 2004. Implementation of the plan began immediately and included the reconfiguration of Decatur¹s elementary schools. The board of education established one early childhood learning center serving children from infants through four years (pre-kindergarten), three elementary schools serving students in kindergarten through third grade, and Glennwood Academy serving all fourth and fifth grade students in City Schools of Decatur.
Glennwood Academy opened its doors in the 2004-2005 school year as a newly configured school for all fourth and fifth grade students in City Schools of Decatur. In 2011 the Academy opened its doors at the new site on Fifth Avenue and The 4/5 Academy at Fifth Avenue was born!
