Hi, You wonder how you can check if you are a good tennis player. If you win sparrings, you can say that you are a very good player. Or maybe the people with whom I play tennis are rather bad and I win with them, I am really an average tennis player. We can answer this question by comparing ourselves to a special scale, which was prepared by the United States Tennis Association (USTA) in cooperation with the United States Professional Tennis Association (USPTA) and International Health, Racquet and Sportsclub Association (IHRSA) .
