Classification Tests in Tennis

Two tennis classifications tests have been devised for use on a tennis court that take only 30 sec. each to give. From the results a teacher can quickly segregate students roughly into ability groups. After two years' experimentation, Hewitt found that “bouncing a tennis ball” above the level of the hips for 30 sec. with a racket and “hitting a tennis ball with a racket on forehand and backhand above the level of the shoulders” for 30 sec. were valid and reliable enough for use to classify students roughly into homogeneous groups. The writer still recommends, where a wall is available for use, that the Dyer wall test or the Hewitt revision of the Dyer wall test with a 20-ft. restraining line be used for classification purposes. Classification scales have been worked out for the two court tests and two wall tests.
