Lexington District One offers 4-year-old kindergarten (4K) programs at various elementary schools across the district.

For students to participate in the district's 4K program, they must be four years of age on or before September 1 of the current school year, reside in the Lexington District One attendance area and meet the at-risk criteria eligibility for enrollment (at-risk is defined as “annual family income of 185 percent or less of the federal poverty guidelines as promulgated annually by the U.S. Department of Health and Human Services, or Medicaid eligible”). Children also qualify in cases of a documented developmental delay, potential developmental delay (screening results), placement in a foster home, or a child who is homeless. Documentation of family or child “most at-risk” conditions must be verified and kept on file for review.
