The purposes of this study were 1) to establish validity and reliability for a modified service test, 2) to determine male and female norms for the service test, and 3) to establish norms for the Kemp-Vincent Rally Test. Subjects were 677 students enrolled in beginning and intermediate tennis classes at North Texas State University, Denton, Texas. Data were analyzed by the two-way analysis of variance to establish reliability. Norms were established by converting raw scores to normalized standard T-scores. Conclusions of the investigation were 1) the modified service test is valid and reliable, and 2) there is a need for separate male and female norms when the skill is governed by strength.
