This study compared the level of agreement and interrater reliability between novice and expert FMS evaluators from observing only the deep squat test. Sixty healthy subjects (36 females and 24 males) between the ages of 18-35 years performed the deep squat test and were scored by 20 FMS raters (experience levels ranging from five months to five years). All subjects who scored a 0 were eliminated from this study. Each of the subjects was video taped from the sagittal and frontal view. Data was determined using a Chi square test (p ≤ 0.05) and a Kappa statistic. The interrater reliability was considered less than chance agreement with a Kappa value = -0.009. The Chi-Square value resulted in a p-value = 0.865, which is greater than the probability of p = 0.05. Results showed that there were no significant differences between the novice and expert FMS raters on the ability to agree 50% or more of the time on the deep squat test. The interrater reliability for the deep squat test resulted to be poor reliability within the two groups of FMS raters.
