In Georgia, to participate in the states Pre-K program, children must be four years of age on or before September 1 of the school year that they want to attend Georgias Pre-K. This means that if a child turns four after September 1, they will have to wait until the following year to enroll in Pre-K. The age requirement is the same for both public and private Pre-K programs in Georgia. It is important to note that Pre-K is voluntary, not compulsory.
