The purpose of this study was to determine how skinfold measurement variability among testers affected % fat estimation in college females. Fifteen college women were measured for 3 skinfolds by 4 female testers: 2 testers had <1 yr of experience and 2 testers had >10 yrs experience. None of the testers received feedback concerning the other testers measurements during evaluation. The Jackson-Pollock equation was used to predicted % fat from the sum of the 3 skinfolds for each tester. A repeated measures ANOVA revealed significant differences among two of the four investigators in the sum of 3 skinfolds and in the predicted % fat values. Intraclass correlation coefficient (ICC) for the %fat values between the experienced testers (ICC = 0.91) was higher than for the inexperienced testers (ICC = 0.83). This study demonstrated that there was a significant difference among skinfold testers for estimating % fat and that experience produced more consistent results among testers.
