SUMMARY OF THE INVENTION

[0016] Objects of patentable novelty and utility taught by this invention are to provide a color-code system of rating tennis skills which:

[0017] provides a publicly visible emblem of professional skill of an individual when playing tennis or participating in professional matches;

[0018] adds attractiveness of an element of gradation of skill to the sport of tennis;

[0019] increases popularity of the sport;

[0020] tends to cause people to stay with it and to succeed in it after they start;

[0021] adds another opportunity for professionally recognized personal success for people; and

[0022] tends to increase the health and happiness of people.

[0023] This invention accomplishes these and other objectives with a color-code system of indicating professional evaluation of tennis skill of a person having a plurality of skill-coded colors of an emblem for display on tennis apparel, instruments and other items selectively. The emblem can include a plurality of coded colors of representations of preferably a tennis ball or other tennis instrument in uniformly differently colored backgrounds. Optionally, the emblem can include uniformly colored representations of preferably a tennis ball or other tennis instrument in backgrounds of a plurality of differently coded colors. The system is a combination of color-code indicia and a method of professional evaluation having steps that include: 1) marking a target side of a tennis court according to target-graded zones of individual strength of a tennis student required to hit a tennis ball to a selected target-graded zone of the target side of the tennis court from an ability-graded distance from a return side of a tennis-court net; 2) evaluating the tennis student's ability to return-strike the tennis ball to a selected target-graded zone of the target side of the tennis-court net from the ability-graded distances for starter students, for intermediate students and for advanced students from the return side of the tennis-court net; 3) testing the tennis students forehand and backhand return abilities by serving a tennis ball from a central target-side end of the tennis court to the tennis student in the selectively return-graded zone; 4) testing the tennis student's abilities to volley, serve, drop-shoot, lob, rally and handle a racket for bounce control in accordance with predetermined point-grading; and 5) totaling points of professional evaluation of the student in accordance with a predetermined rating system that equals preferably zero-to-250 points for lowest-rated ability to highest-rated ability, respectively.
