The King‐Devick test appears to be a promising tool in screening for concussions. However, limited evidence exists on the baseline associations between the K‐D test and age and baseline screening tools used after concussion. Additionally, there are no published reference values for the K‐D test in high school football players. The K‐D test, the Balance Error Scoring System, and the Limits of Stability ( LOS ) test were administered to 157 high school football players. Additionally, a subsample of 62 participants completed the test twice to examine the reliability of K‐D test. There was no relationship between the K‐D test and the BESS , or the reaction time and directional control of LOS test. Students aged between 16 and 18 years demonstrated faster K‐D test performance compared to students between 13 and 15 years of age. However, there was no association between K‐D test and history of concussion. The reliability of the K‐D test was ( ICC 2,1 = 0.89), and the minimal detectable change was 6.10 s. Normative reference values for high school football players are presented in this study.
