Under Kentucky law, all children must be enrolled in and attend school between the ages of 6 and 18. Children can enter primary school at age 5, but only if their 5th birthday is on or before October 1 of the current school year.
Beginning with the 2017-18 school year, the entry date changes from October 1 to August 1. A child who is 6 years old or who turns 6 by August 1, must attend public school. Preschool programs are available for eligible 3- and 4-year-old children as well.
