ABSTRACT.An objective method for predicting the minimum effective weight of high school wrestlers for certified weight purposes—the Tcheng‐Tipton Method—was field tested in Minnesota. Data were obtained from finalists at two State Tourneys. Data were also obtained on wrestlers within a nine‐school Conference at the beginning, middle, and end of a season. The formula is validated on the assumption that State Finalists represent wrestlers who are at their lowest effective weight (i.e., can sustain their skill against equals in repetitive matches). Data collection for the Method was accompanied by measurements of five skinfold sites to examine the implications of body composition variation in assessing individuals whose predicted weight is contested. The findings were reasonably consistent with the underlying assumption of validity, although the reliability of the Method was shown to warrant strengthening via more specific directions for measurement technique. Coach cooperation was encouraging, and the Method appears potentially efficacious.
